Identification of hydraulic fracturing impact factors on the skin effect in the near-wellbore zone of the reservoir

Ларцева, І.І.

The object of this research is the clogging of the near-wellbore zone of the productive reservoir, which leads to the formation of a positive skin factor and a decrease in well productivity. The subject of the study is the impact of hydraulic fracturing on the reservoir properties of the near-wellbore zone, as well as the assessment of the effectiveness of modern numerical modeling methods for predicting well productivity and optimizing technological parameters of production stimulation operations. The study addressed the problem of gas well productivity decline due to the deterioration of the filtration and capacitive properties of the near-wellbore zone of the formation caused by clogging, fluid accumulation, retrograde condensation and other physical and chemical processes that impede the movement of fluids to the bottomhole. The work is aimed at finding an effective stimulation method to increase well production and reduce the skin factor, as well as refining methods for forecasting production rate taking into account reservoir properties.
