Integration of High-Resolution CT-Scan and Minipermeameter Measurements With Wireline Logs To Correlate Thin, High Permeable Zones

Abstract

Abstract The characteristic vertical variation in petrophysical properties across thin (0.6-1.5m) reservoir units was determined at 5 cm intervals from CT-scan and minipermeameter measurements of core samples from the Upper Cretaceous UA-5B sandstone at Patrick Draw Field, Wyoming and the Pennsylvanian Bartlesville sandstone of Oklahoma. This information was used to determine their expected responses on wireline logs. The correlation with this data of a highly permeable interval at the base of the producing shoreline sandstone (UA-5B) indicated that the distribution of this interval significantly affected waterflood production from the field.
