Abstract

Estimation of probable reserves in the Field “RF” is indispensable for the development of the field and increase the productivity of oil and gas in the petroleum field. This research aims to calculation reserves of oil and gas in the Field “RF” by volumetric method using physical quantities and net to gross (N/G) obtained from petrophysical analysis and seismic interpretation to gain bulk volume reservoir. These parameters are used to define of petroleum reserves (OOIP) and gas reserves (OGIP) on Talang Akar Formation and Lemat Formation in the area of research. Based on the analysis of qualitative data logs, it is known that litologi evolve on area of research that is sandstone and shale. From quantitative analysis is known an average value of shale volume content (Vsh) below 30%, effective porosity above 12%, effective water saturation (Sw) below 70%, permeability above 13 mD with oil and gas content. From the petrophysical analysis is known three zone of reservoir in the area of research that is TAF-SS-A, TAF-SS-B and LEMAT-SS. Based on the results of seismic interpretation is known that geological structure evolve in the area of research is the normal fault towards northeast-southwest and northwest-southeast. Each structure in general relatively detached with GOC (Gas Oil Contact) boundaries or OWC (Oil Water Contact) boundaries are different. Based on the results of the calculation of the oil and gas reserves with the volumetric method, a total of OOIP on Lemat Formation is 7.85 MMSTB and a total OGIP on Talang Akar Formation is 1.343,15 MMSCF.
