The analysis of a mature steamflood in the South Belridge field was made possible due to an infill drilling program that provided detailed data from the reservoir. Conventional well log and temperature log data were used to build 3-D models of the sand-shale geometries and temperature structure over the entire reservoir thickness, and oil saturation maps for 14 sands within the reservoir. Graphic visualization of these models allowed insight as to the sand-shale geometry, thermal architecture, and steam-chest development in this steamflood. Volume analysis matched historical production data. Changes in operating policy based on the results of this analysis improved ultimate recovery along with operating efficiency.
Figures & Tables
A collection of papers on computer-mapping case studies, this publication is a useful “go-by” for both beginners and advanced users of computer-mapping software. Fore the most part, the papers concentrate on the geologic features of significance to mapping, the methods used and their justification, and results obtained. The publication is separated into two parts. Part 1 consists of 12 papers dealing with data and surface modeling. Part 2 consists of 7 papers dealing with three-dimensional geologic block modeling.
