The Field Scale Investigation of Water Coning Phenomenon

Abstract:

The study of water coning phenomenon has gained wide interest in petroleum industry during the last few decades and poses a challenge for hydrocarbon production. The simultaneous production of water and oil causes lots of negative effects on the reservoir performance such as significant reduction in oil recovery, corrosion, the cost of oil and water separation, environmental pollutions, and etc. Hence investigation of water coning and finding some solutions seems highly noticeable. For that, we model one of the Norwegian reservoirs which encounters water coning problem by using a black oil simulator. Additionally, since it is not well-matched with its observation data, by the use of SimOpt software, a reasonable match between the simulated and observed data were achieved. After achieving a reasonable match between the observed and simulated data in SimOpt, by the use of ECLIPSE 100 software various scenarios are investigated. Controlling the oil production rate, controlling the field water cut, and the effect of different well completions are different factors whose influences over the water coning phenomenon are examined. Finally, the following solutions are suggested: the varied production rate, field water cut in the range of 0.1 to 0.2, and the open-hole completion.
