Abstract
The drilling of a single development well with two targets separated by a fault in deep water offshore was not expected to be easy. This is the reason of TOTAL Upstream Nigeria Limited willing to engage the services of Schlumberger’s new Logging While Drilling Technologies to enhance the Well Placement process in Well-A and drain the reservoir in a cost effective manner. The decision to go beyond conventional well placement was borne out of the fact that proactive well placement decisions would be a key to minimum reservoir exits. To achieve this, a technology driven approach of detecting the formation changes early during drilling was needed. These changes, when addressed, can be translated into maximizing reservoir contact, limiting well-bore tortuosity thus enhancing optimal production.
