Abstract
In this study, a three-dimensional, three-phase black oil simulator which incorporates static and dynamic local grid refinement procedures to study the water coning problems is developed. Both vertical and horizontal well cases are studied. If water coning is considered to be a well rather than a gross reservoir phenomenon with significant implications at the well, then the local grid refinement procedure is applied only in the wellbore domain. In this study, however, implementation of the local grid refinement is not restricted only to the near wellbore domain as it is also constructed along the water-oil interface throughout the reservoir. Furthermore, since this cone-shaped water-oil interface is not stationary, the effectiveness of the dynamic local grid refinement is examined. A blanket sand reservoir and an anticline reservoir which are coupled with strong aquifers are considered. In the case of a blanket sand reservoir, implementation of a static local grid refinement around the immediate vicinity of a wellbore is found to be sufficiently accurate. However, implementation of the static local grid refinement only at the wellbore domain in an anticline reservoir-aquifer system is shown to be inadequate. The dynamic local grid refinement model gives accurate results in both types of structures.
