An Investigation of the Applicability of the In-situ Thermal Recovery Technique to the Beypazari Oil Shale

Abstract

In this research, a 3-D reservoir model for steam recovery was used to study Beypazari oil shale. In addition, the reaction kinetics parameters of Beypazari oil shale were determined by using the Weijdema's reaction kinetics approach in order to evaluate the applicability of these thermal methods. In the analysis of reaction kinetics experiments, two different temperature regions were observed. In the time versus temperature graph, linearly increasing the temperature zone was considered to be the fuel deposition region and the temperature peak is concluded to be the high temperature oxidation. The results demonstrated that the Beypazari oil shales that were studied were suitable for oil production by the in-situ combustion technique (24.00 lt/ton).
