Abstract

ABSTRACT

The purpose of this paper is to apply R-squared in the analysis of estimated water encroachment into the reservoir. The data used for this work were gotten from records and these data were used to estimate water encroachment using Van Everdingen-Hurst (VEH) and Carter-Tracy models. The R-squared was obtained by plotting the value of estimated water encroachment against time. The results show that all the R-squared gotten in this work are more than 90% as indicated in all the graphs plotted. These results indicated that the variables involved in the computation of water encroachment are all considered, and the results also show that VEH is more reliable since it has higher R-squared. This method of analysis is faster and easy when compared with other methods like Durbin Watson and t-test.

Keywords: Aquifer, boost, petroleum, reservoir oil, water encroachment, model.
