RESERVOIR CHARACTERIZATION AND HYDROCARBON POTENTIAL OF X-FIELD, NIGER DELTA

A suite of geophysical logs comprising of gamma ray (GR), resistivity (LLD), neutron (NPHI) and density (RHOB) logs from two wells within X-field in the Niger Delta, were used to delineate hydrocarbon bearing reservoirs, identify the reservoir fluid types, and evaluate the major petrophysical parameters of the different reservoirs. The petrophysical properties evaluated include porosity, permeability, water saturation, hydrocarbon saturation, moveable hydrocarbon index, and recovery factor. Four hydrocarbon reservoirs were delineated and correlated across the study area. These reservoirs are encountered at a depth range of 3991ft to 11103ft, and the computed petrophysical parameters for the reservoirs gave porosity values ranging from 20.1% to 27.8%; permeability 396.6md to 886.8md, and average hydrocarbon saturation of 88.7%, 73.4%, 76.3% and 86.1% for the reservoirs. These results, together with the moveable hydrocarbon index, and recovery factors (67.1% to 95.3%) suggest the reservoirs contain significant accumulations of hydrocarbons, which can also be produced. Thus, the hydrocarbon potential of X-field is considered high
