On the identification of the reservoir pressures and filtration coefficients of two gas-bearing formations opened by one well from pressure and debit measurements on the mouth
Abstract:
We consider the problem of the determination of the unknown filtration coefficients and formation pressures for two formations exploited together by one well from the measurements on the stationary regimes of the pressure and the total debit on the mouth of the well. The problem is reduced to solving a complex system of three nonlinear equations. We construct an algorithm for its numerical solution and its computer realization for one of the possible variants. An example of numerical solution is given.
