Annotation:
Interstratal gas-condensate crossflows can occur during the exploitation of gas-condensate fields with heterogeneous thickness, even with slight hydrodynamic binder between interlayers with different capacitive and filtration properties. Cross flows result in premature emission of condensate extraction. It has been demonstrated that it is possible to evaluate the current length of the horizontal sections of the well with fair accuracy by applying the linear dependence between the speed of filtration and the pressure gradient.
