PPDM AGM (November 1999)

PPDM’s modest revenues are growing and the association boasts a record number of active workgroups. Current focus is the integration of GIS with the data model and a collaborative venture with POSC to attack the problem of reference data.

The Calgary-based Public Petroleum data Model Association is doing well. A record number of workgroups (6) are active, and there is a modest growth in membership. A project is underway to issue a joint POSC and PPDM set of reference tables (standard codes for countries, logging tools etc.) The increasing international flavor of PPDM is reflected in the new board, half of whose members come from outside of Canada. Much of this interest is due of course to IHS Energy’s use of the PPDM data model in P2000.


A high profile workgroup is studying the incorporation of spatial data into the model. ESRI are helping out here and a vendor-neutral mechanism for tagging existing tables with spatial information has been developed. ESRI demonstrated enthusiastically (and convincingly) how this could be extended with Oracle 8 spatial constructs.


Several speakers reported on the ‘ease’ of implementation and migration to PPDM-based data models. But as Kathy Farr, Mitchell Energy noted, "the anticipated widespread adoption of PPDM by data and vendors and software applications has yet to materialize." Other niggles center on the problem of managing the spectrum of PPDM data model versions in existence. The use of PPDM as a focus for data exchange was the subject of Larry Chadwell’s talk on Marathon’s migration of its legacy database and mapping software to Petrosys’ dbMAP and P2000 from IHS Energy. The system has been put to use in competitor analysis of Marathon’s Rocky Mountain Region Gas Task Force. This links Landmark’s Dynamic Surveillance System (DSS32) to the database to visualize water flood and optimized production. SAS is used to move and reformat data, and MSQuery to populate Excel from the PPDM database. Chadwell concluded that "if the world is going to multiple domain specific databases – then they might as well all be PPDM-based".


IHS Energy’s Pete Stark demonstrated the latest GIS-based data mining technology in P2000. From a map of the world, a selection on horizontal wells brought up the locations of the 20,000 drilled to date. Further drill-down to individual fields in Texas’ Austin Chalk showed the second production peak due to horizontal wells.

reference values

The American Records Management Association (ARMA) stated recently that ‘Codes (reference values) are a much bigger problem than Y2K’. PPDM, along with POSC are setting out to fix this and are encouraging interested parties to join the effort. Schlumberger have submitted well log reference data to the workgroup. If you have codes for submission, or want to help out, talk to www.ppdm.org
