This paper reports on the MWD dual processing resistivity (DPR) measurements and modelling which helped steer a horizontal well through a thin oil zone to avoid a nearby oil/water contact. The horizontal well came on-line flowing 380 bo/d with no water production. Offset vertical wells produce an average of 33 bo/d with an 83% saltwater cut. Until recently, horizontal drilling efforts have been focused on thick reservoirs in which the stratigraphic position of the well bore within the target formation was not critical. Navigation through much thinner reservoirs is now possible with a technique that uses an electromagnetic propagation resistivity tool.
