4D comes of age (September 2001)

A seminal paper presented by BP at the SEG shows how 4D has come out of the R&D closet. Within BP, you no longer have to justify time lapse seismic acquisition. The technology is mature, and the business benefits, a given.

A major step in the recognition of the contribution of 4D, time lapse seismics, was announced at the annual meeting of the Society of Exploration Geophysicists (SEG), held in San Antonio, Texas this month. Speaking during a technical session, David Whitcombe explained why BP is so keen on 4D.

4D Successes

BP’s initial 4D successes were won on oilfields west of Shetland. The Foinaven project significantly reduced the uncertainty of the 15 wells drilled (at a cost of £25 million each) and improved the production/injection strategy. Next, in 1995, the UK North Sea Forties field had run out of economic targets for infill drilling. 4D technology halted, and even reversed this decline.

Robust

BP investigated the overall robustness of the 4D method by comparing oil/brine reflection coefficients over all of its NW European oilfields. The magnitude of this reflection coefficient turned out to be of the same order as the seismic limit of resolution.

Spectacular

Until recently that is. What has gone almost unnoticed in the last decade is a spectacular across-the-board improvement in the seismic method, driving down the signal to noise threshold by a full order of magnitude. As Whitcombe observes - “the seismic method gets better the more it is pushed.” See this month’s editorial for more technical background.

Business issue

This timely technological breakthrough is set to address BP’s fundamental business challenge - that of maintaining around 5% production growth in the face of an underlying 15% decline of existing fields, assuming ‘status-quo’ development. In 2000 4D surveys were acquired on Forties, West of Shetlands, Harding, Montrose and Marnock. A significant success was a new well on the Arbroath field, where a ‘no-change’ area on the 4D survey located a good dry-oil producer down-dip from several watered out wells.

Why not?

Today, for BP, 4D has come out of the R&D closet. You no longer have to justify a 4D survey. But you will have to explain ‘why not’ if you opt not to acquire 4D.

Petris, GeoNet merge (September 2001)

Application Service Provision specialist GeoNet Services is to merge with Petris Technology. The deal will combine GeonNet’s ASP offering with Petris Winds enterprise integration and data management framework.

Petris is to merge with ASP specialist GeoNet. Jim Pritchett (Petris CEO) will be President and CEO of the as yet un-named new company and Pat Herbert (Geonet Chairman and CEO) will be COO. The merger will combine Petris’ application integration and data management with GeoNet's ASP offering.

ASP

While the initial GeoNet business model of ASP access to a variety of third-party applications remains, the company is increasingly turning to the provision of ASP services from within the corporate firewall. Geo-Point of Presence (GeoPOP) offers companies rationalized thin-client access to licensed or proprietary software. The link-up will extend this to the major vendor suites, via the Petris Winds Enterprise integration layer. Jim Pritchett told PDM that the merger would be accompanied by a new cash injection from all existing shareholders.

200 users

GeoNet claims around 200 ‘steady users’ including TotalFinaElf (TFE) and Marathon. Geoscientists with TFE working in Pau, France are connected to servers in Houston, Texas by a 2 megabit per second fiber link.

4D, from Petabyte to Power Point (September 2001)

PDM Editor Neil McNaughton reports back from the Society of Exploration Geophysicists annual meeting at San Antonio where he saw incontrovertible evidence for the efficacy of the time-lapse method - the ‘Power Point proof’. For the formalists amongst you, he also reports on the science behind the technique. Its all to do with oil-brine reflection coefficients....

I hope that all this is not another case of me being somewhat slow on the uptake. Although people have been banging on about 4D seismics for years, as yet the technology has lacked a public airing of its’ proof. No longer. Our ‘take home’ from the SEG was what we judge to be the ‘coming of age’ of the 4D process. A seminal paper by BP’s David Whitcombe outlined the technical justification for a step-change in the seismic work flow.

4D time-lapse

4D (the extra dimension is time) seismics involves repeating seismic acquisition over an oilfield at intervals during its production. The premise is that the seismic method is now so sensitive, that the changes in reflection strength, as water encroaches on the oil, can actually be observed.

Cobe

Well, as they say, seeing is believing, and I would just like first to digress a little on when this is not the case. Recently NASA has shown pictures generated by the Cobe satellite that purport to show what the universe was like a few billion years ago. You probably have seen the oval image of wormy colors - signifying, well, nothing! Because we haven’t a clue what the image should look like, we have no idea whether it has any validity. Such images could just be background noise for all we know.

Jack

The opposite is true of BP’s 4D imagery as shown in a talk by BP’s Ian Jack. We all have a more or less intuitive grasp of how water moves in on an oilfield, and the time-lapse imagery produced from the BP’s seismics is instantly believable. Jack wound-up his talk with a Power Point tour de force – animated 4D movies from half a dozen of BP’s 4D surveys all flashing their way through their production histories*.

Waterfront

The migrating waterfronts made a compelling argument indeed. So compelling in fact that BP is no longer content with this kind of long interval ‘snapshot’ approach to seismic reservoir monitoring. The next step is for permanent seismic arrays over producing fields, with more regular seismic acquisition performed on demand by a shooting boat.

Reflection coefficients

We summarize the BP analysis of oil/brine reflection coefficients below. Most N. European oilfields operated by BP show values in the range of 0.02 to 0.06. BP reckons that until recently, these values were barely above the seismic signal to noise threshold of around 0.02. But BP has found that ‘seismic technology gets better the more it is pushed’ and estimates a current value for the S/N threshold as 0.006.

Order of magnitude

This puts reflection coefficients for all the fields studied a comfortable order of magnitude above the seismic threshold, and gives numerical justification for Jack’s Power Point proof.

More next month

One insider told us that the impact of 4D would be even more apparent at next month’s SPE New Orleans meet. The belief is that petroleum engineers will be abandoning their cellular numerical models in favor of seismically-derived representations of what is really happening in the reservoir. PDM will be there!

*One wonders incidentally if this is not some sort of a record in data synthesis, has so much data ever been so tellingly condensed into a single Power Point slide?

~~~

Regarding the tragic events of September 11th, we received the following from Bjorn Wygrala of IES - we thought he summed up our feelings too, and Bjorn has kindly let us reproduce his message.

“It is difficult to return to ‘business as usual’ without referring to the recent tragic events in the USA and the current risk of increasing national and cultural tensions. As members of the petroleum E&P industry, an industry that is possibly more international than most, we believe that we are in a unique and privileged position to prove that nationalities and cultures are not incompatible. For example, we were recently involved in a project in the Middle East in which 16 geoscientists from 14 nations worked together. There is not really anything special about this in our industry ... and that's the way it should be.”

Geophysics in the affairs of mankind (September 2001)

This illustrated history spans exploration, academia and wartime geophysics. From plate tectonics, through vibrator technology, the interpretation workstation to business intrigue, the 400 page book is a must-have.

Although the subtitle modestly claims that the book is a ‘history of exploration geophysics’ it is much more; the 400 page, well-illustrated tome encompasses submarine warfare, crustal seismology (discovery of the earth’s metal core in 1910) and nuclear test detection (author Bates’ field).

Plate tectonics

There is also detailed coverage of plate tectonics, with a blow-by-blow account of the ‘isolated observations’ leading up to the concept. Coverage of exploration seismology is exhaustive, from Eckhardt’s three trace recorder in 1919, to PGS’ multi-cable Ramform. The battlefield is omnipresent. Ludger Mintrop, founder of Seismos (later to bekome Prakla-Seismos, and later still part of the Schlumberger group) started out by modifying military gear to develop ‘a method for the determination of rock structures.’ The essence of the book is almost an exact reversal of the title. It’s really about people in the affairs of geophysics. The narrative weaves its way around personal histories. and is full of rich anecdotes such as Harry Mayne’s account of the invention of CDP, Carl Savit’s premonition of the bright spot in 1965 and John Crawford’s invention of VibroSeis. The habit of giving newborn babes the unusual name of ‘Géophysique,’ following the passage of CGG’s African prospectors is explained in a footnote.

Intrigue

There is intrigue too - De Golyer went against his Amerada bosses to secretly finance startup GSI, the Schlumberger brothers received cash from their dad, in exchange for a non-compete agreement, and later, Halliburton unceremoniously dumped its geophysics unit in 1994, before buying back into the game with Landmark.

Lacunae

Given the book’s scope, there are inevitable lacunae. Coverage of processing is skimpy - no mention of Dirac or deconvolution, although the MIT GAG gets good narrative treatment. The fascinating pre-numerical LaserScan seismic processing technique and Geco’s Charisma seismic interpretation system are overlooked.

Niggles

Last niggles are an incomplete index and what appears to be rather poor QC at the printers resulting in washed-out photos. There are some great pics though. Next time someone talks about environmental impact, show them the effects of a (1929) 225 kg dynamite shot in coastal Louisiana. ‘Build not buy’ nostalgics should check out Phillips’ magnificent 1957 processing center - those were the days!

New Databanks for Cameroon, Gabon (September 2001)

Schlumberger Information Systems’ Finder data management system is at the heart of two new West African national data repositories to be located in Yaounde, Cameroon and Libreville, Gabon.

Schlumberger’s Finder is the core component of two national data repositories (NDR) in Cameroon and Gabon. The Societe Nationale des Hydrocarbures (SNH), the national oil company of Cameroon, has selected SIS to help create an E&P NDR at the the Centre d’Informations Petrolieres in Yaounde, while Geneva-based Petrolin is working with the Gabonese Department of Hydrocarbons (DGH) to deploy an NDR in Libreville.

Koum

SNH Exploration manager Jean Jacques Koum said, “We selected SIS to implement an integrated data management system to secure and manage all data types available after several decades of exploration and production in the country. This solution will allow SNH to preserve those patrimonial assets and further promote Cameroon’s exploration potential. The NDR is part of an SNH strategic plan to quickly move into the competitive global oil economy, leveraging the new technologies.”

Training

Data types to be handled include seismic, logs, physical assets and production, as well as interpretation results obtained from various sources. A joint SNH-SIS team, under the direction of Koum, has been set up to carry out the various project phases, with a strong emphasis on training and knowledge transfer to SNH employees.

Whole Monty

The NDR will include the following components, Finder, AssetDB, LogDB, SeisDB and ProductionDB. Serge Brun, GeoQuest operations manager added “SNH will be the first West African oil company to deploy a complete data management solution ranging from seismic to production.” More from www.snh.cm

Petrolin

Speaking about the Gabonese NDR, Petrolin project manager Mathew Holsgrove told PDM “The NDR involves the creation of a databank in Libreville for the DGH. Petrolin is helping the DGH recover data from oil companies. This is then indexed, scanned or transcribed before loading into Finder. To prepare the handover of the system to the DGH, we have created indexing procedures and Access database tools linked into the Finder oracle database in order to simplify the transfer of data into Finder. The final part of the Project will be the training of DGH personnel in the population and use of the databank when it is implemented in Gabon at the end of September.”

Seismic sounding (September 2001)

Phoenix Data Solutions’ SeisVu SEG-Y manipulation package has been upgraded. The new freeware version includes a sonification option.

Although seismic data is made up of sound waves, they are usually ‘seen but not heard.’ Phoenix Data Solutions aims to change this and have included in their SeisVu software the ability to play seismics through a PC’s sound card and speakers. Phoenix admits that a serious use of this capability has yet to be found, but believes that the novelty will increase the popularity of its SeisVu freeware.

SEG-Y

SeisVu is a Windows based viewer for seismic data in SEG-Y format. The free version permits (as well as the sound feature) color density, or conventional variable area/wiggle representations. Headers can be checked on-screen, and sample distributions and clipping levels analyzed.

V 3.1

The latest full version of SeisVu (3.1) is now a fully-featured toolkit for reading, writing, manipulating, plotting and editing SEG-Y files. Basic processing steps, such as convolution with a user-specified wavelet, frequency filtering and AGC are included. SeisVu was first released a year ago, since then over 1,200 copies have been downloaded from Phoenix’s web site www.phoenixdatasolutions.co.uk .

SiteScape for Shell E&P (September 2001)

Web-based knowledge management from SiteScape Forum is helping Shell International build communities of practice in upstream.

Shell International Exploration and Production (SIEP) is using SiteScape Forum to create global communities of practice (COP). SIEP claims ‘breakthrough’ performance through sharing and applying talents, learning, and resources globally.

van Unnik

Shell’s Arjan van Unnik says, “We hook up people who are working in related disciplines in Shell companies around the world so they can problem solve and share learnings and ideas. The big trick is to go further than connecting people in the same disciplines. We get excellent cross-fertilization of disciplines – for example, pipeline engineers and corrosion engineers sharing information and ideas, thereby coming up with better and more complete solutions – that’s how we get great value.”

13 COPS

Shell has 13 COPs with over 10,000 users. The main COPs are in sub-surface, wells and surface disciplines, but smaller COPs exist in supporting cross disciplines, like Finance, Procurement, HR, and Health, Safety & Environment. A value review completed in 2000, estimated annual business benefits of over $200 million from this initiative. 

Chevron, Schlumberger in Lost Hills (September 2001)

Chevron and Schlumberger scientists are to collaborate on enhancing recovery from the 90 year old Lost Hills field in California.

Chevron and Schlumberger are collaborating to squeeze the last drop of oil from a field discovered in 1910. The ‘Value Enhancement Alliance’ sets out to improve recovery from the Lost Hills oil field in Kern County, California.

Bakersfield

The alliance, which integrates Schlumberger project management and technical personnel into Chevron’s Bakersfield office, will focus on all areas of the recovery and production process. This focused collaboration is expected to result in new innovations associated with improved drilling and fracture techniques, reservoir analysis methods, and downhole treatment fluids and tools.

Kolstad

Schlumberger Oilfield Services VP Gary Kolstad said, “This is a great opportunity for us to work with Chevron to leverage technologies and maximize the recovery from this challenging field.” Interest was sparked in 1998 when a gas blowout and fire spectacularly demonstrated the deep potential of Lost Hills.

Landmark, Badleys pursue Open Journal (September 2001)

Landmark’s software development and marketing agreement with Badley Earth Sciences is to continue through 2005.

Landmark and Badley Earth Science have signed a 5 year agreement for the continued development and integration of OpenJournal with Landmark’s E&P software suite.

Knowledge capture

OpenJournal has become the solution of choice for many major oil and gas companies as well as independents seeking to improve knowledge capture and sharing among their E&P asset teams. The solution ‘documents crucial decision-making steps’ in an E&P project with a combination of graphical screen captures with associated text and annotation. Through publishing in a Web format, critical expertise can be rapidly distributed and mined across the enterprise as part of a corporate intranet or shared with partners and external experts via a secure extranet.

Gibson

Landmark president and CEO John Gibson says, “OpenJournal enables business units to leverage expertise and enhance group productivity and team collaboration. Easy sharing via the Web builds increased understanding and confidence in E&P analysis and decision. When used with OpenWorks and our recently developed Web OpenWorks, clients have a streamlined workflow of capturing, preserving and sharing knowledge.”

OJ2

OpenJournal2 was released earlier this year with enhancements and integration with Petroleum Place Connect. When used with OpenWorks and Web OpenWorks (wOW), OpenJournal2 is a powerful knowledge-sharing tool, capable of multi-user editing, free text search and project management. An upgrade is planned for early 2002, with improved formatting, exporting and integration with documenting tools in Web OpenWorks. More from www.badleys.com

SEG 2001 San Antonio (September 2001)

PDM attended the Society of Exploration Geophysicists annual conference and exhibition, held in San Antonio this month. With a few hundred exhibitors and ten simultaneous technical sessions there is a lot going on at any time, more than we could take in anyhow! But we offer you an eclectic view of what caught our fancy - from the growth of Linux based clusters and pre-stack seismic depth migration, through a history of seismics on the biggest oilfield in the world to the application of crystallographic techniques to seismic interpretation - and much more...

This SEG started off with a very busy first day. Reports from exhibitors told of a significant increase of quality visitor traffic on the exhibition floor. This atmosphere changed after the tragic events of Tuesday 11th. The SEG wisely decided to continue with the conference, but it was a subdued affair from then on.

Linux

Observable trends include the growing importance of Linux-based clusters for seismic processing and the increasing size and number of network attached storage solutions. Many companies are now offering pre-stack processing with a significant role played by specialist ‘boutique’ seismic processing houses. Our main take home was the coming of age of seismics in reservoir management (see this month’s lead and editorial).

Integration

In a special session on ‘Optimizing integration of Geophysical, Geological and engineering technologies for E&P success’ Exxon’s Randy Ewasko described a ‘volume-based workflow’ with ‘seamless feedback loops at every step.’ This is leveraged and facilitated by the visualization center – qualified as a ‘key element of cross disciplinary learning and interaction.’ The spin-off from such ‘discipline leakage’ can be new solutions to problems such as geological modeling using seismic conditioning, 3D well path planning and steering and Exxon’s next generation reservoir simulator – ‘beyond vendor-supplied software’ – offering co-rendering of engineering and geological parameters. Chevron’s Robert Harding described interpretation as ‘lots of building blocks’ that were not yet put together. One component that does bring some of it together is Chevron’s Common Earth Model – a technology platform that ‘binds communities together.’ Chevron’s Common Earth Model has ‘contributed more than any Knowledge Management initiatives to Chevron’s E&P effort.’

Pliable

Newcomer Idelix was showing off a curious piece of software - ‘pliable’ display technology (PDT), a ‘virtual lens’ that enhances panning and zooming of visual data. Wherever you look, you still get to see the whole data set in concentric areas of diminishing resolution. PDT works with ArcView 8.1 - and was described as the “hottest thing on the floor” at a recent Integraph Geospatial World conference.

Spotfire

Data mining specialist Spotfire is rumored to be making inroads into the upstream, with a 200 seat sale to Anadarko. Spotfire’s Decision Site works with Excel, Access, Oracle or any ODBC-compliant data source. Spotfire provides an intuitive way of accessing tabular data. Originally developed for the pharmaceutical industry, Spotfire now integrates ESRI’s ArcExplorer to allow for geo-located data analysis. Anadarko worked 15 months with Spotfire to extend the program for geochemical data analysis. Cross plots can be produced with consummate ease, a neat Spotfire trick is the way 2 dimensional cross plots are ordered by cross correlation magnitude - before you have even looked at the data! Spotfire provides simple, insightful and intuitive data mining. The company is now working with Landmark on an OpenWorks link.

FreeUSP

Once upon a time, Amoco had a research department where geophysicists beavered away, developing proprietary seismic processing software. But although ‘build’ is no longer cool, all is not lost. BP has placed the fruits of the Amoco researchers’ labors into the public domain. The software is now available, along with a number of other interesting resources, on the FreeUSP website www.freeusp.org

OpenSeis

Calgary-based OpenGeoSolutions is a startup commercial company which hopes to become the ‘Red Hat’ of Free USP. President James Alison told PDM that the company plans to offer a range of services and support around the open source code.

SMT

SMT (Kingdom Suite interpretation software) is ‘closing negotiations’ with Open Spirit Corp. SMT president Tom Smith considers that Open Spirit is now ready for use. SMT was the first company to connect to Open Spirit from Windows-based applications. The Kingdom suite is now out in version 7.0 with multi-user, multi-authoring of interpretations. The software suite runs on Access or SQL Server databases. SMT is also to offer Citrix-based Application Service Provision (ASP) for its clients in-house.

Ghawar

Saudi Aramco’s Kamal M. Al-Yaha spoke on the history of 3D seismics over the Ghawar field (the largest oilfield in the world). During the last decade or so, Saudi Aramco has acquired multiple 3D surveys over the field totalizing 12,000 sq. km. Technology has evolved significantly during this period, with fold increasing from 50 to 1000, the number of channels from 500 to 2800 and production up from 1 to 4 sq. KM. per day. Cost per VP has fallen by 80% while cost per trace is down 95%. Processing changes have been implemented by Aramco’s proprietary processing software. Other significant changes have been seen in computing hardware and visualization technology. The target has also moved deeper – from the Arab formation at 2 km depth to the Devonian at 5 km. Coherency software (developed in-house) has been successful in imaging the Khuff-C level and has provided a wealth of information on structure, reservoir and is underpinning drilling decisions.

OpenSpirit

OpenSpirit has sold 85 development licenses in the last year to 16 software vendors and 5 super majors including TotalFinaElf, Chevron, Agip, Exxon and Shell. Around 400 run time licenses have been purchased by some 20 end-user companies. Most popular OpenSpirit workflows are structural and stratigraphic modeling interactions between T-Surf’s GoCad and OpenWorks or GeoFrame. Open Spirit also offers Windows application developers a shortcut to data access in the main vendor databases. OpenSpirit newcomers include NuTech and Hampson Russel. Paradigm is currently carrying out a technical audit of Open Spirit.

Ikon Science

Ikon Science Ltd. (ISL) is a new company spun off from Ikon Geoscience. ISL’s flagship software is RokDoc, which combines rock physics theory with log and checkshot data to predict facies from seismic data. A new tool, FaultX is scheduled for release in the first quarter 2002. FaultX conditions seismic data and then automatically identifies and extracts fault planes. After extraction and analysis, detected fault planes are returned to the seismic interpretation package for further interpretation. More from www.ikonscience.com

 

Seismic mesh

Landmark researcher Dave Hale has been applying techniques from crystallography to the task of automating the interpretation process. A recurrent problem in interpretation is that of an incomplete representation of a volume by surfaces.

Space filling

We start, in the case of 3D seismics, with a completely space-filling data set, and we want to finish up with a space filled with cells for reservoir flow modeling. But in between, traditional interpretation methods offer us a ‘space’, which is sparsely populated with horizons and faults. Worse, these surfaces may show topological inconsistencies such as overlap, or shortfall – as when a picked surface fails to meet up with a fault. All these create problems as the picked surfaces are used to define the envelope of the cellular fluid flow model. The math used in studying deformations in crystal lattices may help out here.

Lattice

A crystal lattice starts out as a regular space-filling mesh. Hale demonstrated the technique by superimposing a regular 3D mesh onto the output of a Continuity Cube seismic coherency volume. A kind of convolutional process maps out the potential energy of lattice nodes according to their proximity to faults in the coherency volume. This information is captured as a deformation in the mesh – which can then be used to produce a completely automated interpretation – with the added advantage that the topology is space filling and consistent.

HCI

Michael Batzle, Colorado School of Mines has studied various analyses of cross plots relating rock properties to seismic measurement in an interesting and exhaustive analysis. Watch out for very good correlations, which are due to plotting functions dominated by a 1/x à 1/x component. Another caveat is the dependency of seismic response on fluid and lithology combined – so that a brine with 30% porosity can have the same response as oil with 20% porosity. Batzle outlined other ‘gotchas’ in the published quantitative relationships.

Fault detection

Schlumberger’s Stein Pedersen showed new techniques for the detection of surfaces, with impressive auto-location of faults from the 3D seismic volume. Various fault-enhancing attributes are extracted from the data and connected to indicate fault planes. Another impressive seismic display was presented by Magic Earth’s Tera Bulloch, who offered an impressive display of ‘geovolume visualization and interpretation’ (GVI) techniques demonstrated with PGS’ new Brazilian spec data.

Voxel Vision

VoxelVision has produced an innovative piece of visualization hardware. The VoxBox is a cluster of PC’s dedicated to large data volume visualization. VoxelVision has moved the rendering engine onto the cluster. A thick client running on a Solaris or Windows (NT/2000) workstation is fed visualization information over a 100 megabit switched Ethernet network. The Visualization Hub, the ‘VoxBox,’ offers multiple roaming probes and voxel objects, multi-attribute computation and query, volume tracking and data compression.

Tech tid bits

Axis Geophysics selected newcomer Hybinette’s Granite SAN server. Hybinette servers offer CPU modules for Windows NT and 2000, Solaris, PowerPC and AIX. The latest screen from Panoram, the PV230 triple screen workstation offers a 36” x 9” 2.4 megapixel screen with 7,200 pixels per sq. in. Meanwhile SGI was showing off its “dual dual” channel Octane 2 - allowing 4 monitors. Finally, Hays Information Management is to bring out a new Java version of its inventory management system RSO.

Math Cube manipulates seismic volumes (September 2001)

Schlumberger software unit GeoQuest has released MathCube, a seismic volume calculation utility that leverages the OpenSpirit platform for heterogeneous data access.

Seismic interpretation is going far beyond what can be represented even on a 3 dimensional view. AVO, attributes and 4D time lapse data mean that the interpreter is faced with the problem of analyzing a multi-dimensional info-space. Often such analysis is achieved by combining parameters through ad-hoc mathematical manipulations.

Multi-attribute

Schlumberger’s new tool MathCube addresses this problem by providing tools for manipulating multi-attribute 3D, 4D and 4C seismic data. MathCube provides tools to calculate and visualize the differences between AVO and 4D/4C seismic data volumes. Large seismic data volumes can be analyzed utilizing a range of mathematical and logical operators.

Open Spirit

MathCube offers access to 3D seismic data from multiple sources, including GeoQuest GeoFrame and Landmark OpenWorks project databases through the ‘vendor-neutral’ OpenSpirit platform.

Hulme

Geoquest VP Colin Hulme said “MathCube is our second stand-alone application based on the OpenSpirit platform. Through our strong commitment to OpenSpirit, we are bringing productivity-enhancing applications, such as MathCube, to the market faster. E&P companies now have best-in-process software combined with database independence that fit seamlessly into their workflows.” MathCube lets users process AVO and 4D/4C data in-house allowing interpreters to perform unlimited ‘what-if’ scenarios.

A correction from Andersen (September 2001)

PDM mixed up Andersen and Accenture in our piece last month. Michel Meyer puts us right.

In our piece last month on the Andersen Intranet we misreported the ramifications of the Arthur Andersen - Accenture separation. Andersen consultant Michel Meyer put us right. “Many thanks for the copy of your newsletter you sent me. However, I must remind you that Arthur Andersen has not disappeared and has not become Accenture. Andersen Consulting (a former service line of Arthur Andersen) had to change its name after the split with us. They decide to call themselves ‘Accenture’ and are going to the market place with this brand. But Arthur Andersen is still alive. Therefore, as you spontaneously did with the title of your article ‘Andersen's Knowledge Space’, we are simplifying our name and are now just ‘Andersen.’ Best regards, Michel.” More from www.andersen.com. 

GeoFrame 4 released (September 2001)

The latest release of Schlumberger’s application integration platform promises seamless workflow, interpretation management and OpenSpirit connectivity to Landmark’s OpenWorks.

Colin Hulme VP of Reservoir Software for GeoQuest presented the official rollout of the GeoFrame 4 (GF4) integration platform. GF 4 ‘lets users work the way they think.’ The integration suite has been repackaged into Geology Office, offering geological workflow tools and Modeling Office for model-centric earth modeling. Geology Office for instance, lets a user flip between working on a cross section to edit a well. Users can click and fire-up the editor and when through, return to the cross section workflow where they left off.

Rock Cell

A new application, Rock Cell, uses neural net technology to predict rock properties across the reservoir. Reverse faulting can now be handled throughout the interpretation. New in GF 4 is a data management tool allowing for the manipulation of Interpretation Models. Users can now recall ‘the right interpretation at the right time.’ New tool data types can also be managed. Web links allow for the hook-up of the logging truck to the interpretation environment. GF 4 is Open Spirit Enabled for geophysical workflows - GF 4 seismic applications can access data in Open Works. Working the other way round, GF 4 seismic applications are also OpenSpirit-enabled allowing data access from Landmark’s OpenWorks.

Hulme

Hulme said “GF 4 offers a step change in productivity. Shared data access and instantaneous updates within applications give asset teams the real-time interpretive collaboration that is essential in today’s competitive environment.”

Project management

GF 4’s new project data management capabilities, allow updates to be seen in real-time in all applications. The new GF 4 interpretation Model Manager organizes user-created models which can be deployed over the Web. Hulme commented, “Time and time again we’ve seen geophysicists perform interpretations on assets that are then put on the back burner for development. Years go by and the company is ready to move on this asset again often causing the geophysicist to repeat the interpretation work. The interpretation models in GF 4 allow users to capture the essence of interpretations and archive for future use. This saves time when the project is revisited.”

100+ applications

Intriguingly, when many speak of software rationalization, GF 4 boasts over 100 applications, including discipline-specific software for project data management, geophysics, geology, borehole geology, mapping and modeling and petrophysics. GeoFrame, first introduced in 1992, is now used by “more than 90 % of the world’s top 20 oil and gas companies.” Our math makes that 19!
