Abstract

The present study is carried out, using all modern day logs in the eight basement wells of Pandanallur and Madanam Fields of Cauvery Basin, with the objectives to understand open fracture intervals, present day stress direction and reasons for variations in log characters of Basement across different wells. The Basement encountered in wells of Madanam Field has more productive zones as most of the wells are proximal to the faults and the fractures are critically stressed. Reservoir Facies Analysis coupled with semi quantitative water saturation estimations characterize the producible facies in a better way. Development of suitable work flows including all high tech logs for comprehensive evaluation and calibrating with dynamic flow characters make the Basement reservoir exploitation more successful.
