PGS Brings rockAVO to Africa
PGS plans to add well data including rock physics, interactive seismic AVO modeling capabilities, and data atlases to its Africa MultiClient data library.
“The development and inclusion of new rock physics atlases for Africa in the PGS data library will focus on countries and basins that have good links to the PGS MultiClient seismic data library,” says Peter Wijnen VP New Ventures, Africa at PGS.
The integration of seismic with well data helps demonstrate AVO compliance and the integrity of PGS seismic data. This will enable oil and gas companies to calibrate GeoStreamer seismic and PGS’ broadband reprocessed seismic products with conditioned well data and known production scenarios.
Unlocking Reservoir Properties
Rock physics is the link between seismic response and geological properties. It explains how rock properties like clay content, porosity, and fluid fill influence elastic properties such as velocity and Poisson’s ratio and therefore the seismic amplitude response at the well location.
For E&P companies active in Africa, access to a homogeneous database of interpreted well logs will make it possible to analyze the seismic AVO signature based on different fluid and matrix property perturbations.
For African governments keen to promote their offshore areas, the ability to provide harmonized seismic and well data in the same library will be a valuable asset in the competition for oil and gas company interest. Interactive rock physics tools offered in addition to seismic will improve derisking and make it easier for exploration teams to identify play analogs for prospect screening and analysis. Production teams can use them to interrogate nearfield opportunities.
This is good news for everyone interested in West Africa exploration opportunities, governments, and operators,” says Wijnen.
