Maintaining good conditions for petroleum exploitation is an important basis achieving better results. At present, the main reservoir of our oil fields are relatively good, and have entered high water cut, middle late development. Due to long-term exploitation, has suffered a certain degree destruction, resulting in rapid rise aquifers sharp reduction production. It influence on output well fin...

The capillary pressure in a reservoir determines the saturation distribution, and hence the total in situ volumes of fluids (oil/water/gas). The accurate knowledge of the capillary pressure distribution is one of the primary factors that may be decisive in the reliable estimation of hydrocarbon reserves. The centrifuge procedure provides laboratory data, which can be inverted to derive capillar...

Evans Shoal Gas Field comprises the wells Evans Shoal-1and Evans Shoal-2 .Our study aimed to determine the hydrocarbon potential of the main source rock in the study area and analyze the petroleum systems and guide future hydrocarbon exploration and development. The methods used encompass BasinMod techniques using mathematical methods. Analysis of the source rock potential helped to identify th...

In the last decade, ensemble-based methods have been widely investigated and applied for data assimilation of flow problems associated with atmospheric physics and petroleum reservoir history matching. This paper focuses entirely on the reservoir history-matching problem. Among the ensemble-based methods, the ensemble Kalman filter (EnKF) is the most popular for history-matching applications. H...

physical and chemical properties of  crude oil, including viscosity and api gravity, are commonly inherited  from the  early organic matter, environmental conditions in which they were deposited and depth of burial of the source beds. api gravity increases in deeper burial due to higher thermal maturation of organic matter in the source rocks and consequently, generation of lighter saturated hy...

Mathematical models used to describe porous medium flow processes in petroleum reservoir simulation, groundwater contaminant transport, and other applications lead to a coupled system of time-dependent nonlinear partial differential equations (PDEs) [1]. Conventional second-order finite difference or finite element methods (FDMs, FEMs) tend to yield solutions with spurious oscillations. In indu...
