Abstract
The paper presents approaches and methods that allow minimizing the risks of developing gas poorly consolidated reservoirs under conditions of intensive production and a high probability of well watering. On the basis of numerical calculations in the creation of a 4D coupled hydrodynamic-geomechanical model, taking into account specialized studies of core samples with different sample saturations, the effect of weakening of poorly consolidated rocks during a change in saturation from gas to water and subsequent destruction, which causes an increase in reservoir permeability, was taken into account. Based on the obtained updated permeability cubes, an assessment was made of changes in the intensity of watering of gas wells and the impact on the destruction of the reservoir. The results obtained make it possible to analyze and predict production, as well as, if necessary, perform optimization for wells operation.
