The main objective of this research work is to carry out the laboratory study on wet in situ combustion by using combustion tube to evaluate how the target X field core, oil will respond to combustion, generation of flue gases and to determine the engineering parameters of combustion etc. Objective of present work is to carry out simulation of one dimensional combustion tube using CMG STARS to validate simulator thermogram profile with experimental thermogram profile. The feasibility of in situ combustion technique primarily depends on the oxidation characteristics of candidate reservoir oil eg: the sustainability of the ignition front during the course of process. To understand and determine the feasibility of its application to a given reservoir it's necessary to understand the oxidation behavior of the crude oil, the effect of water on combustion parameters and the effect of combustion front on produced liquid.
