Use of Actual Dimension in the Percolation Model for the Calculation of Breakthrough Time in Oil Recovery: Case of Some Niger Delta Reservoirs
This paper calculates breakthrough time for some Niger Delta reservoirs using a percolation model. The model is less cumbersome and time saving when compared with traditional methods such as the Buckley-Leverett method. By incorporating some reservoir specifics, such as actual reservoir dimension, into the model used in this paper, better results which approximate empirical values closely are obtained. The fact that breakthrough time is reservoir specific is confirmed.
