Chemical transformation model for numerical simulation of the oxidation of oil in the reservoir (in situ combustion)

Authors: Plynin V.V., Fomkin A.V, Urazov S.S. (Zarubezhneft JSC)
Projects to develop oil fields, which include air injection, potentially very effective, especially when extraction of heavy oil. However, to date, in situ combustion is poorly studied, and hugely complex for numerical simulation.  It is shown that the major problem is the creation of an adequate chemical transformations model (CTМ). An approach to forming CTМ is proposed on the basis of three principles, which avoids a number of blunders committed by some researchers. The article provides an example of the formation of CTМ based on the proposed approach and its discussion.
