Title: Produce more oil from low-relief structural reservoir with strong edge/bottom water by secondary development——A case study of Oriente Basin,South America
Abstract: Reservoirs in Oriente basin of South America are low-relief reservoirs with strong edge/bottom water and are controlled by strike-slip wrench structure.Because the oils have low API gravity and water phase permeability is high,the initial production was high,bottom water broke through quickly and stable production period was very short.Through numerical simulation and study of oil production in 22 horizontal wells,secondary development has been conducted to make the advantage of high liquid-producing index and try to adjust production system below critical producing pressure differential of bottom water coning and to keep balance of original formation pressure system,hence to control bottom water coning and obtain high oil production.After using this method,single well production of 3 newly drilled horizontal wells has increased 30%.The study and application of this technology provide a new way for stabilizing oil production and controlling water in late high water cut stage of reservoirs with low-relief and strong bottom water.
