METHOD FOR IMPROVED WORK WELL Russian patent published in 2016 - IPC E21B43/267 

FIELD: oil and gas industry.

SUBSTANCE: in the process of intensification of the well, which includes a test injection of fracturing fluid and a tutu fracturing fluid with proppant, correcting design gap and conduct basic process fracture during test pumping as the fracturing fluid used linear gel, which provides a limited retention time of proppant in suspension, as proppant a mixture of proppants having improved resistance after deposition of the fluid passage gap, after the test injection well is kept under pressure until the deposition of the proppant into the lower portion of the fracture gap, the amount of proppant in the fracturing fluid administered sufficient to fill the cracks gap to 0.1-0.3 the height of the crack.

EFFECT: invention may find application in the intensification of the well, which revealed a layer with low-permeability reservoir.
