In the Republic of Belarus at present one of the most important problem is development of hard-to-recover reserves of oil, confined to low-permeability poorly drainable heterogeneous and split formations, which contain more than 50% of remaining hydrocarbon reserves. Hydraulic fracturing of formation (HF) is one of the most efficient methods of increasing productivity of wells, exposing such formations. During 2007-2010 Production Association « Belorusneft» gained experience of conducting hydraulic fracturing in carbonate and terrigenous reservoirs of deep-sunk (up to 5 000 m) low-permeability deposits. Current effect over performed operations enables to conclude on reasonability of application of the given technologies on the oil fields of Pripyat downfold. Hydraulic fracturing allows to activate the production from low-permeability formations and get incremental ultimate recovery from the deposits, which showed no effect when other stimulation treatments were performed. Implementation of hydraulic fracturing technology in carbonate formations along with fixation of created filtration channels with propping agent allowed to put on production the number of wells, which showed no effect when other exploration methods were used.
