Title: Experimental And Modeling Of Friables And Stone Oil Reservoirs Consolidation Using Steel Making Slag
Author: Al Awad, Musaed N. J.
Abstract: A mathematical model was developed simulating the process of sand production in under downhole stress state. The model was derived based on Mohr-Colomb failure criterion, Darcy equation for radial flow and reservoir stress state. In order to predict the on-set of sand production (critical drawdown) using the developed model, data obtained from the consolidation study in connection with the physical and mechanical properties of the consolidated samples as well as the stress state acting on the reservoir under investigation were used as an input in the model. Results of this study showed that a mixture of Steel Making Slag, calcium chloride (CaClz), calcium hydroxide (Ca(OH)2) and water was able to control sand production with a 22% maximum loss in productivity. The mathematical model predicts the maximum allowable drawdown and sand-free production rates of the consolidated friable sandsone samples under downhole in-situ stress state. Furtherore, the model can be applied as well to predict the critical drawdown and sand-free production rates for naturally cemented formations.
