METHOD OF DIFFERENTIATED DETERMINATION OF FILTRATION PARAMETERS OF JOINTLY OPERATED PRODUCING FORMATIONS Russian patent published in 2001 - IPC

Abstract RU 2172404 C2

FIELD: oil producing industry; determination of coefficients of water permeability, oil permeability, piezoconductivity and productivity of jointly operated producing formations; applicable in more accurate prognostication of said parameters and formation pressures. SUBSTANCE: method includes measurement of hydrodynamic characteristics in producing well and subsequent processing of results. Results are processed by computational solution of offered mathematical expression. EFFECT: higher accuracy in result interpretation, simplified and short-time field hydrodynamic investigation. 3 dwg, 1 tbl
