ESTIMATED ULTIMATE RECOVERY CALCULATING METHOD FOR OIL AND GAS RESERVOIR

摘要

According to an embodiment of the present invention, as an ultimate recovery calculating method for a shale gas reservoir using a computer, provided is an estimated ultimate recovery (EUR) calculating method for a reservoir including: (a) a step of setting reference values of parameters of gas production amount estimation models of the reservoir close to an actual gas production amount of the reservoir based on observation data of the reservoir; (b) a step of setting multiple major parameters influencing a gas production amount most among the parameters of the estimation models; (c) a step of calculating an EUR of the reservoir based on probability distributions of each major parameter.;COPYRIGHT KIPO 2016
