... tight and high permeability reservoirs, for both with and without cross-flow. With this new approach, engineers can apply material balance methods to better understand multilayer gas reservoirs and to make better reservoir management decisions. system pressure Material Balance Equation recovery...

... the number of iteration on calculating drainage area. Abstract This paper presents the development of material balance equations (MBE) for coalbed methane (CBM) reservoirs. This method is appropriate for determining Original Gas In Place (OGIP) and predicting fluid mechanisms in coalbed methane...

.... The results show that the decrease degree of gas deliverability is different and it depends on the permeability modulus in the formation on which the gas well is located. And by combining the binomial equation of gas wells with material balance equation, the basic performance prediction model is established...

... Abstract Predicting water encroachment can be of critical importance in describing and managing a hydrocarbon reservoir. This study focuses on the use of the generalized material balance equation (GMBE) proposed by Walsh, et al 1 , 2 along with the analytical solution to the diffusivity...

... Abstract This paper presents a robust and rigorous method for the numerical solution of the material balance equations of compartmented gas reservoirs. The method is based on the integral form of the material balance equations and employs an implicit, iterative solution procedure. The proposed...

... and those from simulation study, would be demonstrated in this paper. In this study, material balance equation for a gas reservoir and van Everdingen-Hurst model for an aquifer were solved simultaneously to calculate cumulative gas production. The result was then compared with cumulative gas production...
