This research work will identify the petroleum reservoirs that are capable of holding significant amount of petroleum in the wells, which will result from the consideration of porosity, hydrocarbon turation and other petrophysical parameters.įield evaluation in a complex sedimentary environment is always tedious due to problems associated with imaging of the subsurface in such areas. It also deals with the depositional environments and reservoir sand bodies that characterized the wells. Reservoir characterization deals with sedimentology, structural geology and petrophysical parameters of the wells formation. The plotting helped in the correlation of the two wells and determined the reservoir potentiality of the wells. Similarly, the reservoir potential of the well X2 is at depth between the range of 4057M and 4097M.The depth between 2205M and 2910M are intercalation of sand and shale whiles the depth 3000M to 35lOM are purely shale because of high Gamma ray values from the logs.From the raw data collected from the Agip energy, reservoir characterization of the two wells was carried out by plotting depth values against resistivity values and depth against gamma ray. The depth between 2750m and 3340m are purely shales. The reservoir potential of the well Xl is between depth 3533M and 3850M while the depth between 580M, the topmost of well Xl and 3850M, the deepest part of well Xl. The aims and objectivity of this research work is to use geophysical borehole log data to determine the reservoir of the various stages in the wells, correlate the wells in the field, determine the economically viability of the wells and to determine the different lithology encountered at various depth in the wells.The well Xl and well X2 are located at SouthEast of Brass and South West of Bonny. This research work is basically based on the use of Geophysical wire line log data of well Xl and well X2 in X-field, Niger Delta for the evaluation of the reservoir potential of the wells.
