Abstract
This work presents the results of 3D Geological Modeling with a focus on the onshore field, in the context of the Potiguar Basin. Therefore, the object of study is the silisiclastic reservoirs of the Açu Formation, unit 3, which correspond to the Albian/Cenomanian fluvial sandstones, in which hydrocarbon accumulations are housed. In this way, a better understanding of the reservoirs of a part of the field was sought through the integration of geological and geophysical information in the Leapfrog software. Where the gamma rays (GR), density (ROHB) and neutron porosity (NPHI) profiles were used to identify regions of reservoir rocks and sealants or non-reservoir. And the microresistivity profiles (MSFL), to determine the water saturation in the formation, and from that the oil saturation in the respective intervals. Through modeling, it was found that the highest relative oil saturation is accumulated in the upper portion of the sequence, in reservoir R1, where the average is 45%. In reservoir R2, intermediate, the average is 30% and in reservoir R3, in the lower part, 38%. And a total volume of hydrocarbons of the order of 1.17 MM3 was estimated for the three reservoirs. From this integration, despite the stage of production categorizing the field as mature, it appears that there are still significant volumes to be exploited.
