Administratively, B Field is located in Riau Province which is encompassing an area of 59.59 km2. B Field, also, is a northwest-southeast trending anticline that is located in the northern part of Central Sumatera Basin. Reservoirs in B Field are parts of Duri Formation. The study is focusing on three reservoirs interval within the Duri Formation with sandstone as its lithology which are Reservoir A, Reservoir B, and <br /> <br /> <br /> <br /> Reservoir C. The main purposes of this study are to determine the reservoir model of those three reservoirs and subsequently, to estimate the original oil in place (OOIP) of those three reservoirs. Several methods have been performed in order to achieve those main purposes which are well data analysis (well to well correlation using sequence stratigraphy concept, electrofacies and cutting analysis, and petrophysic analysis), seismic data analysis (determination of depth structure map and determination of each reservoir geometry), and reservoir modelling (determination of 3D structure model, determination of each property model, determination of fluid contact, and the estimation of original oil in place (OOIP)). By implementing those methods, it is interpreted that there are three major geological structures that has developed in B field which are northwest-southeast trending anticline, northwest-southeast trending thrust fault, and northeast-southwest <br /> <br /> <br /> <br /> trending normal fault. . Facies of Reservoar A and Reservoar B are fluvial channel and estuarine channel whereas facies of Reservoar B is estuarine channel with the same sedimentation direction which is northeast-southwest. The estimation of original oil in place (OOIP) is achieved in the three reservoirs interval within B Field which is 250.05 MMSTB.
