Reservoir Characterization in ‘O’ Field in the Niger Delta Using Oil Well Log Data
Journal Title: Journal of Geography, Environment and Earth Science International - Year 2017, Vol 13, Issue 2
Abstract
Suites of borehole logs comprising gamma-ray, electrical resistivity, neutron and density logs from four wells in the offshore Niger Delta were evaluated for their hydrocarbon potential. The various lithologic types penetrated by the wells were differentiated on the basis of the Gamma-Ray log into sand, shale and shaly-sand beds. Three (3) sand bodies were delineated and correlated across the (O) field. The three sands were further identified as potential hydrocarbon reservoirs. The evaluated petrophysical parameters for the reservoir layers have porosity, range of (24 -30)% and hydrocarbon saturation, range of (72 - 80)%. The use of the geophysical well logs have allowed for the evaluation of rock formation properties such as hydrocarbon saturation, porosity and reservoir thickness that will make drilling and production decisions a lot easier. The bulk of the hydrocarbon was encountered between (2920-2978)m within the transitional Agbada formation. Gas-Water Contact has been encountered by the well at 2984 m TVDSS.
