New technique of vertical-lateral cycling-process using horizontal wells
New technique of vertical-lateral cycling-process for gas-condensate pools is presented based on horizontal producers and injectors. Two conventional problems of the cycling-process are dry gas breakthrough via high-permeability streaks and watering of producers as the result of water coning. Those problems are mitigated by placing producers near the top of the reservoir and dry gas injectors near the gas-water contact level. 3D multiphase simulations were performed for a number of 3D heterogeneous sector models. The results of the simulations justify that the proposed technique can provide increased condensate recovery together with lowered water production, especially for gas-condensate pools with bottom water.
