PROCEDURE CONTROLLING PROCESS OF FLOODING OF GAS WELLS Russian patent published in 2003 - IPC

FIELD: oil and gas industry, development of gas fields. SUBSTANCE: procedure includes execution of standard gas dynamic examination of gas wells under stationary conditions of filtration and determination of coefficients a and b of filtration resistance. Analysis of dynamics of coefficients a and b of filtration resistance in time is conducted and graphs of their change in time are constructed. Then values of coefficients a and b of filtration resistance are compared with previous values and conclusion on availability of stratal water in bottom hole of pool is made by sudden growth of values of coefficients of filtration resistance. EFFECT: minimized operational expenses and irretrievable losses of gas. 2 dwg
