Abstract

Evaluating reservoirs by conventional wireline logging in open hole has become an accepted and necessary technique over the years. In geologically uncertain areas, open hole logs run in a particular well provide data not only for the well being evaluated but also for future offsetting wells. One obvious drawback with these logs is that rig time must be expended to condition the hole to log, to do actual logging, and then to recondition the hole to cement.
