... based on the Dover UTF Phase B pilot site was constructed with physical dimensions of 600 m long by 150 m wide by 24 m high. As shown in Figures 1 and Figure , the reservoir model was discretized into a regular Cartesian grid consisting of 251 gridblocks in the down-well direction, 50 gridblocks...

... displacement takes place at the thin interface between the steam chamber and the cold non contacted oil zone. Therefore, fine cells or gridblocks are necessary at least in the region covered by this interface. Without dynamic sub-gridding, it means that whole the simulated domain must be discretized with fine...

... in reservoir property is called the sensitivity coefficient. In this paper, we describe the use of the adjoint system of equations to compute the sensitivity of wellbore pressure, water-oil ratio, and gas-oil ratio to changes in gridblock permeability and porosity. Unlike some other methods of computing...

... filter cakes removal by natural cleanup when the well is put under a drawdown pressure difference. A flow simulator taking into account the near well permeability variation has been developed using cylindrical grid with very small gridblocks around the well. Laboratory data obtained on sandstones damaged...
