In the detailed description of reservoirs, thin bed resolution by wireline techniques is a vital factor. For example, the evaluation of laminated shaly sands can be best accomplished by a sensitive delineation of sand and shale layers. Rather than running a tool designed exclusively for this purpose, money can be saved if the desired information can be derived from a logging tool routinely run for other purposes. Dipmeter surveys, particularly those with a calibrated resistivity scale, can be used for this purpose. Several descriptive properties can be derived from the dipmeter survey: | In the detailed description of reservoirs, thin bed resolution by wireline techniques is a vital factor.
