PRODUCTIVITY EQUATIONS FOR A MULTIPLE-WELL SYSTEM IN CIRCULAR AND RECTANGULAR RESERVOIRS

摘要: Currently, in the oil industry productivity equations for a single well are erroneously used all reservoir systems, regardless of interference effects on flow rates different wells same drainage domain. This paper presents steady-state and pseudo-steady-state multiple-well system circular or rectangular reservoirs. The proposed equations, which relate production rate vector to pressure drawdown vector, provide fast analytical tools evaluate performance multiple that located arbitrarily reservoir. solutions verified with numerical simulation two examples. perform match solutions. It is concluded that, given number wells, boundary conditions skin factor have significant single-well total system.
