PPDM meet hears from Devon/Noah, OGP

How Devon has transformed its data asset. Oil & Gas Producers’ new positioning formats.

Speaking at the PPDM Association’ Oklahoma City data management luncheon this month, Devon Energy’s Matt Harris, with help from Patrick Kelly of Noah Consulting, told how his company has turned its data into a ‘valuable corporate asset.’ The key software tool underpinning Devon’s well data is Peloton’s WellView suite along with the MasterView I/O SDK and Informatica’s data quality toolset (IDQ).

Devon is now a ‘data driven organization’ with an ‘accountable’ data management organization that assures quality, accessible data through standard definitions. Devon has over 200 IDQ rules running alongside audit checks to ‘address data issues before they occur.’ The IDQ rules add business process and data governance to WellView’s application logic. The Peloton suite is managed by a team based in IT helped by a data governance group with stakeholders from the business. Devon’s rules are embedded in a data work stream with most activities executed in a SharePoint workflow that leverages Informatica’s metadata manager and business glossary.

One example of the technique’s success is Devon’s greenhouse gas reporting which has reduced data defects from around a million in October 2013 to a few thousand by the end of the year. In 2014 serious defects have been virtually eliminated.


John Conner introduced the new Oil and Gas Producers’ association’s positioning exchange said to bring significant benefits over legacy positional data management. The OGP ‘P’ formats are direct replacements for the SEG-P1 seismic positional exchange format and the UKOOA’s P2/91/94 formats for marine acquisition. The most currently used format today is SEG-P1 which has outlived its usefulness. A modern 3D marine survey may record 30 or 40 position types but SEG-P1 only supports 1 per file. Some, like source, receiver and CDP are not even identified. Headers are freeform and often unpopulated. Conner warns, ‘Every export to SEG-P1 is a potential loss of knowledge and accuracy.’
The new OGP formats have a robust, common machine-readable header that eliminates hand-entered metadata by hand. They also offer more robust positional integrity on loading into the workstation and less overhead for data managers. Adoption will be a transitional process as application vendors and seismic data processors adapt their software to the new formats. The formats are a free download from OGP1104. More from PPDM.
