Abstract

Inconsistent hydrocarbon distribution trends within small oil fields are commonly sought to be explained by small scale sealing faults, often resulting in a network of faults in a small area. Generally these faults are not apparent on the seismic section and interpreted differently by different interpreters. A similar trend has been witnessed in a small but highly prospective Miocene oil field in Upper Assam, where different interpreters have interpreted various faults to explain the mounting tally of dry wells falling within the prospective area.
