Abstract
A novel well reservoir coupling method is developed using a three phase, black-oil, transient reservoir simulator and a black-oil steady-state vertical well simulator. The integrated model is based on an imposed wellhead pressure and an initial pressure and saturation in the reservoir. The simulation than proceeds to advance the solution in the reservoir using a set of steady state solutions for the well until a converged solution is achieved for each time step. The reservoir is simulated with imposed internal boundary condition of pressure, set to be iteratively equal to the bottom hole pressure in the well, coupling the system. Also, the mass flow rate is balanced explicitly at the interface between well and sand face. The convergence of interactions is obtained for each time step before advancing. Due to the lack of field data for testing some hypothetical situations are being tested. As preliminary results a demonstration of the capabilities of the program is presented, showing promising results.
