... Abstract As a rule, the basis for engineering calculations for monitoring the productivity of wells is the model of stationary and unsteady inflow in homogeneous formations or formations with a given type of zonal heterogeneity. This is due to the presence of analytical models for these cases...

...). The field case cited in the article describes a specific implementation of an MRT, called "radial deconvolution," in which the central (tested) well is equipped with a bottomhole pressure gauge. As a result, the interference of the offset injection and production wells to the tested well is estimated...

... conditions. For assessment of stimulation efficiency, different techniques can be used: decline curve analysis (DCA), production rates analysis before and after stimulation, analysis of reservoir properties in the near-wellbore zone and in the reservoir using pressure build-up (PUB) curves. Each technique...
