We were kindly supplied with a review copy of the latest edition of James Murtha’s book*, “Decisions involving uncertainty, an @Risk Tutorial for the Petroleum Industry.” First off, this is not really a book about uncertainty analysis. It is an oil industry-specific version of the @Risk manual. As such it does a credible job and walks the reader through the use of forecasting, volumetrics, porosity and saturation modeling with uncertainty (or perhaps that should be with clarity?). @Risk offers many bells and whistles, with lognormal, triangular error distributions and user-assigned dependencies of variables.
All in all a straightforward introduction to the subject of Monte Carlo analysis (MCA). Incidentally, for those who already have the book, there is little that is new. In fact there is less in this issue that in previous editions, the Lotus 123 references have been eliminated. Elsewhere the main changes concern the alignment of the text and illustrations with later versions of Excel and @Risk itself.
You may be wondering why this brief book review appears in this month’s editorial. The reason is that in chapter 1, Murtha asks “why do risk analysis,” and makes the case for stochastic (statistical in other words) as opposed to deterministic analysis. It seems to me that in this simple introduction, Murtha, like the whole risk analysis industry, overlooks an alternative was of analyzing risk. A much simpler way in fact. Let me explain. Murtha offers the universal problem of computing volumetric reserves as a starting point for his argument.
Where A is the area in acres, h is the net pay in feet (European readers will excuse the quaint units) and R is the recovery factor (bbl/acre ft.). The argument moves on quickly through the deterministic approach (which gives a single value) through the scenario approach (worst, most likely, best) and on to stochastics, the subject of the book. For those of you who have not come across MCA, the technique involves performing a large number of ‘simulations’ of the reserve calculation using input values picked at random from within a probable distribution. It is the ‘casino’ aspect of the method that gives it its name.
MCA is above all great fun. I remember the first time I saw a colleague program a MCA simulation, and we watched the old HP plotter whack, whack, whack the crosses onto the paper, building up a cloud of points showing the range of possible values of oil in place. MCA has the virtue of being simple to implement, and requiring considerable compute resources to run on all but the simplest models. A dream for the computer buff. But is it always necessary?
Certainly, oil companies today are extremely interested in computing uncertainty, but if you have a million cell reservoir model, and a few dozen input variables, a fully fledged MC simulation for every input would probably take longer than the field’s life-span to complete. While pondering Murtha, I remembered something from high-school days. Wasn’t there a way of doing the error analysis more deterministically? In the old days this was called “error analysis.” Well I won’t get too far into this, the old memory isn’t what it was, but it involves “drunken walks” for added parameters and added errors for multiplied terms. Error analysis says if there is a 5% error (standard deviation) in each term of the A*h*R equation, then there will be a 15% error in the computation. Easy!
Why do the proponents of MCA not consider error analysis? Could it be because it is too simple? That deprives engineers of the pleasure they get from plowing through reams of MCA computations? Deprives them of their futzing in fact.
In these days of empowerment, tools like MCA allow just about anyone to do science that is arguably outside their own “core competence”. In other industries, like drug testing, statistics are performed by... statisticians! Giving a tool like @Risk to a geologist, engineer or financial manager may not be the most straightforward way of analyzing risk. In fact, as a model’s complexity grows, the results will probably make for rather dubious science. Pulling triangular distributions out of thin air, and coupling and uncoupling variables at will, may be within reach of the software, but the result? It will probably be something of a drunken wander away from the truth, proving yet again the Churchillian epithet alluded to in the title.
Putting it another way, whatever they tell the shareholders, to launch a multi-billion dollar development offshore west Africa on the basis of a couple of exploration wells and a 3D seismic survey takes more balls and faith than statistics!

PetroWeb’s Autodesk-based GIS front end is to be used as an entry point to the IHS Energy data hosting center announced in last month’s PDM. The companies have signed a strategic agreement to provide “best-of-breed” Internet solutions to the petroleum industry, including application service provider (ASP) and data service provider (DSP) components. Data service provision involves the update and maintenance of data, and allows a client company to eliminate the associated expenses of managing these functions in-house.
IHS Energy Group will provide the databases, data hosting center and data management systems, which are built on IHS’ PIDM and IRIS21 data bases. PetroWeb, the e-commerce arm of Petroleum Exchange, will offer its Internet-browser-based map interface to deliver real-time data access to third-party commercial and internal corporate data. With PetroWeb, oil and gas companies can view, purchase, and download data from IHS Energy Group in a secure environment. Such data can be combined with internal databases using their corporate Intranet assuring integrated data delivery to the desktop.
Mike McCrory, executive VP and COO of IHS Energy Group said “PetroWeb’s strength lies in its capability to link our commercial data with the customer’s own proprietary data in a single, map-based interface.” Darcy Vaughan, president and CEO of PetroWEB added “The combined strengths of IHS Energy and PetroWEB will provide the marketplace with cost-effective solutions based on the latest technologies for accessing, managing and delivering data.”
Seitel, Inc. has formed, a wholly-owned subsidiary, Seitel Solutions Ltd., to create a web-enabled data management system that will provide access to the largest seismic data library in North America. The Enterprise Data Management System will be based on a Storage Solution Provider (SSP) model.
Seitel President and CEO Paul Frame said “Our goal is to create a network of information that we own and control, and that generates significant additions to revenue, opportunities and shareholder value.”
The implementation of the Enterprise Data Management System will be led by Bill Leakey, who recently joined Seitel, Inc. as Vice President and Chief Information Officer. Leakey was previously CTO with Kelman Technologies.
The rapprochement between CGG and Paradigm Geophysical has provided a fast-track to commercialization for software developed by French oil conglomerate TotalFinaElf. Most all CGG interpretation software, from Integral Plus to Stratimagic, originated as in-house developments by Total or Elf. Stratimagic for instance, originated as the Elf-developed Sismage software. TotalFinaElf has signed further agreements, directly with Paradigm, for the implementation, within Paradigm’s GeoLog, of in-house developments Diamage and Facimage.
Diamage offers tools for advanced interpretation of array wireline log information, while Facimage introduces automated facies classification techniques. The tools, patented by TotalFinaElf, have been developed over years of testing and calibration with core data, and are said to facilitate the analysis of large volumes of well log data.
Elf Exploration Production is a corporate-wide user of GeoLog and its petrophysics interpretation package. Integration of the two products within GeoLog will be carried out in Paradigm's Well Technology R&D Center in Brisbane.
TotalFinaElf Petrophysics Technical Manager Gilles Bourdarot said “We will benefit from having our proprietary techniques available to all engineers and operating subsidiaries in a well-supported, commercial environment. This will give our scientists more time to pursue original research.”
Paradigm Chairman, Eldad Weiss said “As a result of this agreement, TotalFinaElf's experience will soon be available commercially.”
Seismic Unix from the Colorado School of Mines Center for Wave Phenomena is acknowledged as being the standard for open source code seismic processing software. For PC users, the source code has been recompiled for Windows, and a graphical front-end added, by Geneva-based GeoSoft. The resulting commercial package, Visual_SUNT is now available in a new release, version 5.
GeoSoft chairman Jacques Jenny told PDM, “ Since version one, released in 1998, Visual_SUNT has become a popular tool in universities throughout the world. In addition to the visual interface, Visual_SUNT provides tools such as interactive FK analysis, frequency spectra and deconvolution. Key feature of version 5 are, powerful and easy geometry input, residual statics, unlimited number of traces and a powerful new printing module.
All the usual Seismic Unix modules are available in Visual_SUNT with the familiar Windows interface. You can process a complete seismic section without writing code or use SU’s powerful batch capabilities. Visual_SUNT is now without any doubt the best ratio price/powerful and the most easy to use for 2D seismic processing.
This program is used in many Universities all around the world for teaching.” The new versions are available on CD-ROM from GeoSoft. A sister product, WinSism 8 is also available for refraction processing. Compilation of the UNIX code, previously handled by Hugh Winkler of Scout Systems, is now performed by GeoSoft.

IHS Energy Group has moved from acquisition to divestiture mode, judging from a recent deal with Geological Data Services (GDS) of Addison, Texas. IHS has sold the assets of its Reservoir Geology Division, including ReservoirID, its reservoir-geology database, to GDS. GDS develops and maintains subsurface, log-derived formation-top files. Formed in 1984, GDS has data files covering West Texas, the U.S. mid-continent, and several Rocky Mountain basins.
These files include more than 580,000 correlated wells and 270,000 additional uncorrelated wells. Other GDS products include the exclusive distribution of the Topographic Mapping Company’s digital land grid, and the construction of customized, proprietary-data files. Under the terms of the deal, GDS has an exclusive license to the ReservoirID data, which contains more than 100 parameters and calculations for each producing reservoir, including log-derived porosity calculations, water saturation levels and reservoir thickness calculations.
Nearly all of the data purchased is in the Anadarko Basin, located in Northwest Oklahoma and the Texas panhandle.
Bruce Smith, VP of U.S. Data Services with IHS said “The ReservoirID database is the covers nearly 45,000 well completions. This data supports GDS’ core business, so the sale made sense for both companies.”
GDS president Rick Haines added “The ReservoirID database and Reservoir Characterization Studies are tremendous contributions to the knowledge-base regarding the Anadarko Basin. The addition of these new data files to our existing database will enhance our clients’ exploitation and development efforts by allowing them to quickly determine re-completion and offset potential, as well as identify acquisition opportunities. In response to requests from our customers, we also plan to expand the Reservoir Characterization Studies to include other basins.” More from www.gdsdatamaps.com.
At last month’s SEG in Calgary, PDM caught up with a very busy Eldad Weiss, chairman and CEO of Paradigm Geophysical. Our first question was about the headline deal between Paradigm and CGG...PDM - what is the intent behind the deal?
Weiss - There is a clear need for integrated reservoir characterization and we have noted the changing role of geophysics in this respect and we are now integrating our software across the different disciplines. Paradigm is cementing its position in this field by adding Flagship's product line to its portfolio. Integral Plus is an important addition because of the corporate data management platform*.
PDM - but Integral Plus was given very little visibility by Flagship.
Weiss - Perhaps, but we think differently. We see Integral Plus as an important data integration tool with strong DM capabilities thanks to the central Oracle database. This may have been hard to incorporate in Flagship's “plug-in” positioning. But we do not have the same view and will be building on this infrastructure. Moreover the Integral Plus datastore is built around the latest Oracle technology. Of course we also like StratiMagic's elegant solution to a complex problem and will be leveraging this and other of our products with our latest application - Reservoir Navigator which lets you move through the whole reservoir dataset, with multi-attribute 3D data on disk. This technology allows roaming through massive datasets on disk with low cost hardware.
PDM - we titled our latest issue - CGG Paradigm Rapprochement - is this a fair appraisal of the current situation?
Weiss - Perhaps, but we have constraints on the degree to which we will let CGG move into our equity. CGG cannot increase its equity position on the open market and Paradigm has an option to buy-back. The deal is intended to cement our technological relationship.
PDM - Both organization are CORBA aficionados.
Weiss - yes we see eye to eye on leveraging CORBA integration and are expecting significant technology sharing - especially in the field of 4D/4C processing and reservoir characterization.
PDM - but there must be a significant amount of overlap and rationalization in the offing.
Weiss - We do intend to rationalize infrastructure. To me it is like the European auto industry. There the same basic chassis serves in a variety of models. It will be the same for our shared infrastructure. We are now the only integrated platform covering the whole spectrum from pre-stack seismics to interpretation. We are #1 in seismic processing software, #3 in interpretation software and #5 in processing. Moreover, our customers appreciate our independent viewpoint.
*PDM Note—Integral Plus was one of the first integrated interpretation suites to work from a central database.
Halliburton and Landmark are teaming with time-lapse boutique 4th Wave Imaging Corp. of Laguna Beach California. Halliburton has entered into a strategic agreement with 4th Wave to offer time-lapse vertical seismic profile (4D VSP) services to its clients. Landmark is to cooperate with 4th wave on software development
4th Wave was founded last year by David Lumley, now President & CEO. Lumley was previously leader of the 4D Seismic Reservoir Monitoring program at Chevron Petroleum Technology Company. 4th wave has licensed proprietary 4-D cross-well technology from Chevron.

T-Surf has released Jacta, a plug in for its flagship GoCAD geological modeling software. Jacta adds uncertainty analysis to reservoir description and modeling. Jacta walks users through the process of reservoir characterization and model building, capturing the uncertainty inherent in each domain measurement.
Jacta captures structural uncertainty at seismic resolution as well as time-to-depth conversion errors. Internal architectural errors due to well density can similarly be quantified. Other error sources such as facies, petrophysical property distribution, fluid properties and contacts are integrated. Jacta provides a focus for the asset team by bringing together different domain specialists. This enables an integrated analysis of model construction and highlights the impact of different inputs, their uncertainty and interdependencies, on reserve estimation.
The software was originally developed under contract to TotalFinaElf and is now used by Chevron, Texaco, BHP and other members of the GoCad consortium. Jacta links to Microsoft Excel for economic feasibility analysis. An optional link with StreamSim’s 3DSL, the streamline simulator, allows dynamic investigation of high-resolution geological models.
Petroleum Software Technologies is offering a free log calculator on its website . The software allows for quick-look calculations of porosity, water saturation etc. Recommended use is for trial and error determination of sensitivity to different parameters.

The OGFS provides information on industry players with capital to invest in drilling and exploration prospects and for reserve purchases. Users can research a company’s backgrounds, its area of interest, deal criteria and spend history. The directory also offers contact information on investment decision-makers.
For those seeking loan financing, the directory includes information on other investment sources such as private capital providers, lending institutions, investment bankers, and alternative financiers. Hart’s VP Bob Jarvis said “We are very excited to have Petris publish the Oil and Gas Finance Sourcebook over the Internet. With Petris' keen technology edge, this book becomes the online handbook for oil and gas companies and individuals seeking to finance some of their activities.” Visit PetrisX on www.petris.com.
A new tape subsystem has been released by IBM. StorageSmart LTO Ultrium Data Cartridges support the Linear Tape-Open Cartridge Memory (LTO-CM) chip, which reads and writes data with a radio frequency transmission.
The LTO-CM enables simultaneous transfer of cartridge during media load and unload cycles, improving data access speeds. AImed at the midrange and network tape storage environments, the new subsystems provide scalable solutions through to multi-terabyte libraries.
The high-end StorageSmart SL7500 Tape Library offers around a terabyte per square foot of floor space. Individual tape capacity is quoted as 100GB (uncompressed*) and data transfer to and from the media is currently around 15mb/s. Currently the drives are SCSI-attached, with fibre channel connectivity via third party NAS and SAN gateway adapters.
Future plans include a native Fibre Channel-Arbitrated Loop attachment (FC-AL) interface. Other features include a barcode scanner for optical cartridge recognition and automated tape inventory. A touch-screen LCD panel enables local review of library status and provides control over local functions.
*PDM Note - IBM’s marketing material entertains some confusion as to data capacities and bandwidth. Here all figures are uncompressed.

DEAL, The CDA/UKOOA information portal has announced the rollout schedule for its first service offerings. Already up and running are the Information Services - “iDEAL,” and the Data Marketplace “uDEAL.” The DEAL Unified Data Network - eDEAL is due for release on 15th December 2000.
iDEAL offers quick and simple access to a single, complete and reliable reference set of basic spatial and attribute data over the UKCS. DEAL prime contractor BGS is assembling the data from a variety of sources and populating the DEAL database after quality assurance.
uDEAL is a catalogue of UKCS geotechnical data products. The service is intended as a marketplace for users and vendors alike. Data vendors can publish details of their data products on DEAL by associating them with an existing spatial object (a well for example) or by creating objects on an existing map layer (creating an outline polygon showing the areal extent of say a regional geological report). Such information will be made visible to end users through the DEAL GIS interface. Fully-fledged e-commerce is envisaged in the future.
DEAL’s most ambitious concept will be a paying service. uDEAL extends data marketplace to include entitlement and e-commerce. uDEAL draws distributed data stores together into one unified virtual system. Users will be able to see what data exists and what data they are entitled to. First targeted data type is SEG-Y stacked seismic.
Schlumberger, although first in the UK’s data portal business with the LIFT facility, was originally excluded from DEAL. But the service behemoth has ‘dealt’ itself back in, with the acquisition of DEAL hosting contractor, Data Marine Systems (DMS). DMS was acquired last month by Schlumberger’s Network Solutions unit for an undisclosed sum.
Network Solutions president Xavier Flinois explained “This acquisition will enhance our global delivery infrastructure for secure connectivity. DMS owns and manages both a global VSAT based network and an extranet that provide secure and remote network access to over 100 companies in the oil and gas industry.” DMS was founded in 1988 and has grown to become a 200 employee company generating $50 million turnover.
DMS private network, OPNet offers a 2MB/sec bandwidth in the North Sea, with an upgrade to a new fiber network underway. DMS director Alan McLeod plans to “reproduce our successful Aberdeen-based partnering network in other regions such as the US, Latin America and East Asia” with help from the new owners.
The US Minerals Management Service (MMS) has produced a CD-ROM of geographical data for the Gulf of Mexico. The Gulf-wide Information System (GWIS) is a geographic database containing information on environmental resources along the Gulf of Mexico coastal and near shore areas from Corpus Christi, Texas, to Tampa, Florida.
The database was developed jointly by the MMS, GOM States and the National Oceanic and Atmospheric Administration. The CD contains a consistent overview of marine and coastal data for the study area and was designed for oil-spill contingency planning, oil-spill response, and environmental planning and assessment in the marine and coastal areas.
The GWIS CD includes information on environmental features such as terrestrial and marine wildlife, managed lands, transportation, and socioeconomic features. GIS data is provided in ArcView shapefiles with tabular data in dBase format. The CD-ROM is available from the MMS for a very reasonable $20.00. Buy yours now from www.mms.gov.
