A case study of hydrocarbon prospect evaluation in north Exito field by using seismic attribute and seismic inversion

Exito field is one of the oil fields which located in the Mahakam Delta, East Borneo. Geological structures that control in this field is a subducted anticline structure towards the north. The wells drilling in this area is only conducted in the southern part of the Exito field. This study is focused only on the interval Gamma Exito Field. This interval has the most reservoir unit and productive one. The interval Gamma is bounded on the top and the bottom marker. This study aims to interpret seismic attribute and seismic inversion. The seismic attribute that is used in this study is the root mean square (RMS) attribute. The application of this seismic attribute is carried out to see the direction of paleo sediment pattern of the reservoir. On the other hand, the seismic inversion is used to describe the porosity of the reservoir. In addition, the data from the interval Gamma dipmeter is used to validate the analysis of paleo sediment patterns. The result shows that the northern part of the Exito Fields ha...
