An integrated study of the Grayburg/San Andres Reservoir, Foster and South Cowden Fields, Ector County Texas. Quarterly report, January 1--March 31, 1997

PDF Version Also Available for Download.

Description

The goals of work done this quarter were (1) to analyze the preliminary seismic inversion model for the Grayburg A, B, and C sequences and the upper San Andres formation; (2) modify the inversion model to improve its accuracy and to include the deeper Holt Formation; and (3) test various rock property quantities against the improved model and other seismic attributes using refined analysis boundaries. A satisfactory inversion model and porosity analysis remains to be accomplished, but much has been learned about the modeling and analysis processes. Qualitative comparison of sonic logs with the inversion model traces in profile view ... continued below

Description

The goals of work done this quarter were (1) to analyze the preliminary seismic inversion model for the Grayburg A, B, and C sequences and the upper San Andres formation; (2) modify the inversion model to improve its accuracy and to include the deeper Holt Formation; and (3) test various rock property quantities against the improved model and other seismic attributes using refined analysis boundaries. A satisfactory inversion model and porosity analysis remains to be accomplished, but much has been learned about the modeling and analysis processes. Qualitative comparison of sonic logs with the inversion model traces in profile view shows great similarity and success is being made toward good quantitative results. Progress on these goals is described. Additional studies were carried out on the following: Witcher No. 12 core and completion, water analyses, reservoir simulation, reservoir engineering, and water quality for injection.
