Generalized Black Oil Modeling
Abstract/Contents
- Abstract
- The objective of this work is to develop a modeling scheme with plainness in mathematics,numerical computation, and Programming, which does not require complicated or skilled programming. Such a scheme would be the first step for the construction of a general-purpose modeling system.A simple and straightforward scheme for a generalized black oil simulator was developed. It utilizes a compositional ;approach, finite difference Jacobian estimation, and a modified Newton method. The scheme uses a phase pressure and two component mass fractions as primary variables. Other variables including saturations are determined by flash calculation. A simple flash procedure was derived for the generalized black-oil assumptions, which allow the gas component to dissolve in the water phase and the oil component to vaporize into the gas phase.Some algorithms to improve the efficiency of finite difference Jacobian estimation, without any loss of generality, were also derived. They can be classified into what is known as the CPR approach in the: numerical analysis literature. The use of finite difference Jacobian approximation expands a good environment for structuring various elements of the simulator, such as the property models, the flow model, and the well model. A rigorous well model is used.A two-dimensional, three-phase coning simulator based on the scheme was developed. The simulator was tested with the SPE second problem and others. The results show the validity of this method. In addition, the SPE second problem is discussed, along with the results obtained by this simulator, in an appendix.
