Abstract
"Fast combustion assisted gravity drainage" (FCAGD) process is a novel heavy oil recovery enhancement method which is a specific combination of the two in-situ combustion process and steam assisted gravity drainage process. In this paper, the novel FCAGD thermal heavy oil recovery enhancement process has been presented by an improved simulation with an Eclipse500 simulator and has been analytically validated with Visual Basic.net code. As a result, the oil recovery factor of the simulation of the FCAGD process has been increased to about 48%. But, in comparison to its improved one, it is less efficient because as a result of the improved FCAGD process simulation, the oil recovery factor has been increased to about 52% in the reservoir. This novel process can be substituted with other thermal heavy oil recovery enhancement methods under proper technical circumstances with a greater recovery factor of oil produced.
Key words: Fast combustion assisted gravity drainage, improved simulation, thermal heavy oil recovery enhancement methods.
