Velocity analysis and use of ‘V0-k’ depth conversion approach with probabilistic consideration helped to convert time to depth with base case structural crest at -6700fl TVDss. The approach generated three possible cases of GRV’s that were incorporated with Petrophysical parameters to generate the volume of hydrocarbon in place. The GIP probabilistic ranges from the result are: low case (14.4 bcf), base case (22.6 bcf) and high case of 36.3 bcf. STOIIP base case calculation estimated a total volume of 3.40 mmstb. Petrophysical analysis estimated an average porosity of 21% in the discovery well with OWC at -6821 and GOC at -6813ff TVDss.Oil stain in core is from 6785-6801.6ft TVDss. The pressuredepth plot over the well show anomalous data points that probably related to supercharged’ formation. Reliability of the pressure data to infer flui...

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.
