Evauation of Gas-in-place and Production Behaviors in Natural Gas Resevoir of Free Gas Type

Abstract

In this paper are discussed the evaluation of gas-in-place and production behaviors in natural gas reservoir of free gas type, and the properties of gas reservoir fluids such as gas converesion factor, solubility and water formation volume factor. These discussion are chiefly based upon the calculated results which were computed under pre-determined conditions, In these calcu-lation are involved the encroachment effect of water into the gas reservoir and the evolution effect of natural gas from liquid phase within the reservoir.
