Well Log Lithological Analysis and Petrophysical Parameters Calculation of Miocene to Recent Formation Reservoirs in Well P10, Offshore, Northern Rio Del Rey Basin (Southwest Cameroon, Gulf of Guinea)

The P10 well is located offshore, in the Northern part of Rio Del Rey basin southwest Cameroon. Although most prolific coastal Cameroon given production results from several fields southern part, yet it remains very little explored its northern part. This work evaluation petroleum potential Basin using a combination "Quick Look" interpretation logs recorded and "complex matrix" facies analysis different lithofacies through neutron porosity - bulk density (NPHI-RHOB) delta time sonic (DT-RHOB) diagrams. composite log includes Gamma Ray log; Caliper Deep Resistivity log. In addition to this log, geological end report completed refine results. Ten (10) near sand/sandstone reservoirs were delineated between 950 1803 TVD m (true vertical depth meter) with good porosities (12% <Φ< 30%) as mineralogical composition dominated by quartz. Clay volumes are relatively lower than 18% except R5 R6 where they around 24%, giving latter sandy-clay lithology. Reservoirs R2 R4 contain oil, WOC (Water Oil Contact) at ~1172 GOC (Gas 1169 m. R6; R7; R8; R9; R10 all Gas Water WGC ~1431 m; 1530 1690 ~1790 respectively. light these results, there clear dominance gaseous hydrocarbon over oil-impregnated ones study area. provided can serve baseline data for future oil gas exploration projects Basin.
