Geological and statistical modeling of oil recovery of carbonate formations

Abstract

Abstract For the conditions of fourteen groups of low productivity, complex features in the carbonate reservoirs of the Volga-Ural oil and gas province were constructed geological and statistical modeling that allows predicting the ultimate oil recovery factor for deposits similar to those studied when solving various development tasks. Based on the consideration of cause-and-effect relationships between geological and technological parameters, the physical interpretation of the obtained models is given. It is established that the variety of oil deposits in carbonate reservoirs according to the conditions of occurrence, geological-physical and physical-chemical properties of reservoirs and their saturating fluids requires a differentiated approach when modeling and using models of the oil recovery process.
