POSC’s ‘broad church’ embraces an integrated information platform for the digital oilfield, a global well unique ID initiative and WITSML formats for well path and temperature surveys.

POSC CEO David Archer cited a recent Gartner study which found that ‘industries on standards do better’. E&P standards are needed for regulatory reporting, asset management, portfolio review and production optimization. ‘Standardizing IT helps companies get to their core business’. POSC is also working on an XML protocol for distributed temperature survey (DTS) data and a draft ProductionML standard.


The Norwegian Integrated Information Platform (IIP) for reservoir and subsea production is the most ambitious oilfield standards project since POSC’s Epicentre and Oracle’s Synergy. POSC’s IntOPs SIG is a participant, along with Statoil, Hydro, DNV, National Oilwell and others. The project began in June 04 and is set to cost $3.8 million over 3 years. Deliverables to date include some impressive slideware of Statoil’s Tyrihans (an Asgard outlier) subsea completions. Tyrihans is to be developed as a highly instrumented field with real time data from wells and permanent bottom for 4D seismic monitoring. This year Tyrihans will deploy a well ‘stream’ containing subsea equipment withWITSML drilling and logging, production and HSE reporting. In 2006 the IIP will extend to include automation, operations, reliability, maintenance and reservoir characterization. In the final year of the project, decision support tools will be deployed for real time rule-based notification and visualization. After testing, the IIP will be submitted to ISO as a standard for Subsea Production and Operations. An IIP ‘dictionary of terms’ will be ‘delivered’ to the W3C. Of potential interest to the W3C semantic web community is OWL-based information retrieval and categorization software. Project scope is mind boggling. IIP aims to integrate everything, from geometry (GIS, CAD, and earth model) through 4C/4D seismic, drilling, logging, production, HSE etc. ‘in one standard.’

Data Store Solutions

Alan Doniger presented the results of the Data Storage Solutions SIG. This is a ‘broad church’ of a grouping which includes the Global Unique Well Initiative (GUWI), previous work from the Shell Discovery project and reference data standards for lithology and coordinate reference systems. Both the lithology and fluid properties protocols are heading for inclusion in WITSML. The DSS SIG aims to ‘increase awareness’ of the EPSG coordinate reference database. WITSML 1.3 is ‘nearly aligned’ and a web-based coordinate reference service is planned for Q4 2005. This will be deployed as a GML and WITSML server. The DTSML temperature survey is also a WITSML-like format leveraging namespace and units of measure as does the new Well Path Data Transfer Standard.


The ConocoPhillips and Shell-lead global unique well identifier GUWI project, also known as the world wide well project, produced an initial discussion document early in 2004. Following review by vendors, a letter of intent was submitted to oil companies. Now a request for proposals has been drafted for a ‘global clearing house service’ including ‘customer facing’ services for registration, query etc. The GUWI service will be deployed progressively starting from exploration and development ‘hotspots’. The AAPG is ‘on board,’ IHS has offered to carry with what they do already. According to GUWI lead, ConocoPhillips John Adams, ‘There is no intent to replace the API in USA or the Canadian numbering system.’


Somewhat belatedly, Norwegian Tieto-Enator presented the results of a 2003 project carried out for the Norwegian trade grouping OLF and the major Norwegian operators. TietoEnator has standardized daily operations and production reporting into an XML format. This has solved the problem of variable quality regulatory reporting and eased data aggregation and analysis.


The COPEX production and well data reporting format (originally developed by PGS for Petrobank) was used, along with the Schlumberger Oilfield Glossary, API standards and ISO 15926. NPD standards and key performance indicators supplied by Petoro also ran. XML reports are now stored in TietoEnator’s LicenseWeb. This allows for query and extraction to ad hoc reports in Microsoft Excel. The data footprint covers operations, alarms, production allocation, gas lift and HSE. Pilot projects have leveraged the technology on BP’s Valhall and Statoil’s Asgard fields. The early XML mock-up is to be retooled as a contribution to the WITSML production standard.
