چکیده مقاله:
Streamline simulation recently has gained much attentions due to its advantages over conventional finite difference (FD) and new reservoir engineering data that this technology can provide. In this work streamline simulation has been extended for the first time to simulate carbonated water injection (CWI). In the numerical model proposed here, first governing equations describing flow of oil and gas phases each containing an additional component of Co2 are presented. Pressure is solved implicitly in conventional 3D grid and Darcy velocity is obtained at the faces of the blocks using pressure field. Streamlines are launched from the face of injection well and using semi-analytical algorithm of Pollock, they are traced to the face of production well. Then governing equations are transformed to the time of flight coordinates and are solved along the streamline grids.In this work a hypothetical 2D reservoir has been utilized. First the amount of Co2 at injection well has been set to zero so that the simulator simulates plain water injection and the results have been confirmed by results from FD solution of Eclipse. Then Co2 is allowed to dissolve into water at injection well to simulate CWI. Distribution of saturation and compositions are obtained along streamlines and then are mapped back to 3D grids. After 4.9 pore volume injection of CW, 24.1 percent additional oil recovery was achieved.
