Selection of allowable gas extraction modes for wells of gas fields

The approach is considered for solution of a stationary distribution problem of gas pressures and flows of crude gas in gas-gathering systems. The approach meets cumulative gas production requirements and technological constraints as boundary conditions. Clustered gas-gathering systems, which use internal energy of natural gas itself, represent tree structures of pipe lines. Therefore the solution of the stationary mode selection problem is reduced to the solution of a sequence of one-dimensional nonlinear equations with monotone functions.
