Summary:
Scaling spontaneous imbibition (SI) data is essential in understating the behavior of naturally fractured water-driven reservoirs. The efforts of developing scaling groups has been the focus of many studies since 1950’s. In this paper we highlight the outcome of a detailed investigation on the influence of different rock and fluid properties on the quality of the scaling group proposed by Schmid and Geiger. These rock and fluid parameters can have either a direct effect on the scaling law, or an indirect effect through the semi-analytical solution of SI. This analysis will allow us to identify how imbibition assisted recovery curves change with varying physical conditions, and whether the scaling group will hold regardless of the varying range of parameters.Based on our analysis, we notice that the variations in different parameters including initial water and wettability of the studied core did not affect the quality of the scaling group, and the results matched the semi-analytical solution. The results of the work done in this study can be used to produce more experiments with varying operating conditions and compare the outcome against similar numerical models.
