Application of Multi-Stage Hydraulic Fracturing (MSHF) In The Development of Deep-Lying Deposits with Low Permeability of Hydrocarbon Fields

Abstract

As a result of the development of deep-lying deposits, additional volumes of gas and gasoline can be extracted from fields with declining production, and new production methods can be introduced. New methods of intensifying production are required when well productivity decreases during the development of gas condensate fields. Deep-lying deposits can be increased by hydraulic fracturing (HF), which can be considered one of the main methods of improving well productivity. To maintain reservoir rock flow characteristics and create large fractures with high permeability, hydraulic fracturing is essential for low permeability deep deposits. As part of this work and for the development of deep deposits with low permeability, multistage hydraulic fracturing (MSFH) is used as the most effective technique for intensifying gas and condensate production. There were two types of hydraulic fracturing processes used: large-volume hydraulic fracturing, where 300 tons of proppant were injected, and HiWay hydraulic fracturing, where 200 tons of proppant were injected. According to the study, HiWay technology significantly reduces the proppant required to secure hydraulic fractures, by less than 38.5% compared with high-volume technology. A 2.5 fold increase in flow rate is observed at the wells of the deep-lying deposits of the studied field after these geological and technical measures are carried out, and the hydraulic fracturing effect lasts for three years.
