Abstract: | A method of estimating the change in well productivity resulting from the hydraulic fracturing of a finite reservoir, piecewise-homogeneous in the horizontal and vertical directions, with an arbitrary number of cracks is proposed. A correction coefficient that enables these estimates to take into account the effect of capillary trapping of mud and fracturing fluid filtrate is derived [1, 2]. Novosibirsk.
