Abstract

Seismic methods of amplitude atribute and sweetness can be used to delineate faultthat becomes potential traps in a hydrocarbon reservoir. To characterize the reservoir, an acoustic impedance seismic inversion method is performed using seismic data and well data as its control. Map results attribute amplitude and sweetness indicate three types of faults in the research area that is normal fault, reverse fault, and strike slip fault. The strike slip fault on the north side of the leaked study area becomes the hydrocarbon migration path trapped by the impermeable layer above it. The leaking nature of the strike slip fault on the north side of the study area is also reinforced by the magnitude of the porosity around the slip fault strike when compared to the surrounding area. The result of inversion of acoustic impedance in Tensleep formation shows low acoustic impedance that is about 34.000 (ft/s)*(g/cc) to 36.000 (ft/s)*(g/cc). The effect of normal fault that divided the research area becomes two dome can be seen in the inversion resultthat showed a lower acoustic impedance value on the north side of the research area. The lithology present in the Tensleep formation consisted of sandstone and dolomite inserts with effective porosity at 25-1x-14 wells of 0.074, 48X-28 wells of 0.108, wells 61-2-x-15 of 0.085, and 67-1-TpX-10 wells of 0.079.
