ABSTRACT

Mobil Producing Nigeria’s Oso Field produces 120,000 barrels of oil per day from late Tertiary sands in the Niger Delta offshore. The reservoir consists of anastomosing fluvial deltaic sands which are difficult to correlate from well to well using traditional log correlation techniques. Image log data from Formation MicroScanner (FMS) logs and dipmeter data tied directly to cores permit detailed analysis of channel thickness, orientation, and distribution. This geographic understanding of the sand bodies enables geoscientists to construct a detailed “plumbing” diagram of this complex reservoir, thus allowing for better exploitation.
