The annual Professional petroleum data management (PPDM) symposium was held in Kananaskis, Alberta late last year with around 150 in attendance. The eponymous PPDM data model—now at version 3.9 has grown to some 2,700 tables, 71,000 columns and 26,000 constraints. PPDM’s ‘what is a well’ initiative has blossomed into a well hierarchy that EnergyIQ has deployed for Concho. The hierarchy is now a foundation for lifecycle data integration.
Marc Fine (451 Data Solutions) provided an
introduction to
the intricacies of well status and classification. Terminology—even
that imposed from a regulator can be confusing. An ‘active’ well in
Arkansas is one that is capable of producing hydrocarbons, in
California it is any drilled and completed well and so on. The PPDM
well classification and status workgroup has mapped codes from 39
regulators in Canada and the US. The agencies have been contacted to
check definitions and so far, 1,500 codes and definitions have been
mapped to PPDM ‘facets.’ Facets
allow multiple types of
classification to be defined separately re-using the same information.
Examples include the regulatory life cycle and wellbore status facets.
Clay Harter from event sponsor OpenSpirit
introduced its pre-built
‘palettes’ that have been leveraged in various workflows. These include
data sync across a corporate well master and Schlumberger’s
Studio/Petrel environment. OpenSpirit is even used to sync between
Prosource and Studio (both from the Schlumberger stable!). Another
palette connects Petrel to Landmark’s engineering data model EDM so
that perforations, casing and tubing data and drilling events can be
viewed. A subsurface search option is claimed to ‘make finding and
using subsurface data as easy as finding a restaurant on Google maps.’
