Exploration for channel sandstone reservoirs is one of the more challenging areas in today＇s economic climate. While the rewards can be substantial, the downside has always been the unpredictability of reservoir delineation. A new approach to help determine the orientation of these typically long, narrow and multilinear sandbodies is presented. Borehole imaging techniques based on microconductivity changes in the rock, such as employed by Schlumberger＇s Formation MicroScanner (FMS)* and, more recently, the Fullbore Formation MicroImager (FMI), provide detailed images of a formation. This allows the interpreter to recognize stratigraphic structures such as crossbedding, erosional surfaces and drape features as well as textural properties of the rock (Serra, 1989). The present study describes how the recognition of these sedimentological structures in the channel sands of the Middle Devonian Gilwood Member of the Watt Mountain Formation in north-central Alberta, has aided in the exploration for these attractive reservoirs.
