Application of reservoir characterization and advanced technology to improve recovery and economics in a lower quality shallow shelf carbonate reservoir. Progress report, August 2, 1995--August 3, 1996

PDF Version Also Available for Download.

Description

The Oxy West Welch project is designed to demonstrate how the use of advanced technology can improve the economics of miscible CO{sub 2} injection projects in lower quality shallow shelf carbonate reservoirs. The research and design phase primarily involves advanced reservoir characterization and the demonstration phase will implement the reservoir management plan based on an optimum miscible CO{sub 2} flood as designed in the initial phase. The reservoir characterization phase is near completion with the tomography currently being integrated into the petrophysical and 3-D seismic interpretations. The petrophysical analysis has yielded both an improved net pay criteria and a method ... continued below

Description

The Oxy West Welch project is designed to demonstrate how the use of advanced technology can improve the economics of miscible CO{sub 2} injection projects in lower quality shallow shelf carbonate reservoirs. The research and design phase primarily involves advanced reservoir characterization and the demonstration phase will implement the reservoir management plan based on an optimum miscible CO{sub 2} flood as designed in the initial phase. The reservoir characterization phase is near completion with the tomography currently being integrated into the petrophysical and 3-D seismic interpretations. The petrophysical analysis has yielded both an improved net pay criteria and a method of calculating permeability from log response. The 3-D seismic has enhanced the ability to distribute the reservoir properties between wellbore control points. During the reporting period, work was completed on the CO{sub 2}, stimulation treatments and the hydraulic fracture design. Analysis of the CO{sub 2} stimulation treatment provided a methodology for predicting results. The hydraulic fracture treatment proved up both the fracture design approach and the use of passive seismic for mapping the fracture wing orientation.
