DETERMINATION OF PAYOUT BED FAILED ZONE Russian patent published in 2015 - IPC E21B43/04 

Abstract RU 2548629 C1

FIELD: oil-and-gas industry.

SUBSTANCE: proposed process comprises pre-pumping into the well with registration of well pressure, annulus pressure, concentration, flow rate and weight of the agent. Results of said pre-pumping is mathematically interpreted by definition of parameters that rule out the collapse of compacted layer, in particular, existence of tolerable pumping volume and pressure. Pumping volume is defined by determination of volume, failed zone radius, failed zone depth and difference between volumes of failed zone and compacted layer shell. Pumping critical pressure is defined by modified Iton method with the help of calculation formula.

EFFECT: higher accuracy of determination.
