Abstract

Naturally fractured reservoirs may occur in both siliciclastic and carbonate rocks, but are most common in the latter. The only direct methods of detecting the natural fractures are by borehole cameras, or by coring and direct observation of that core. This paper examines core evaluation techniques which may be used to assess natural fracture systems. Correlation of the results of detailed core/fracture analysis with wireline logs, allows logs to be interpreted with greater confidence.
