Title: Application of reservoir characterization and advanced technology to improve recovery and economics in a lower quality shallow shelf San Andres reservoir. Quarterly progress report, April 1--June 30, 1997

The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted to reservoir characterization. Technologies being demonstrated include: advanced petrophysics; three-dimensional seismic; cross-well bore tomography; advanced reservoir simulation; CO{sub 2} stimulation treatments; hydraulic fracturing design and monitoring; and mobility control agents. During the quarter, cross well seismic work continued, using the revised processing software. The validity of the seismic-guided mapping was confirmed by the drilling of a well. Revised CO{sub 2} performance projects were run using the enhanced geologic model in which the seismic data had been incorporated. Facilities for supplying and distributing CO{sub 2} to the area were designed and bids solicited for the materials and construction.
