METHOD FOR DEVELOPMENT OF SHALE OIL AND GAS BEARING DEPOSITS AND PROCESS SYSTEM OF EQUIPMENT FOR ITS APPLICATION Russian patent published in 2015 - IPC E21B43/16 E21B43/24 E21B43/26 

FIELD: oil and gas industry.

SUBSTANCE: according to the method capital mining operations are carried out on penetration and developing access channels to a productive formation of a deposit. Underground mining and development operations and field operations on the well production of shale oil and gas are performed using multistaged hydraulic fracturing or thermal effect on the formation. A shale oil- and gas-containing deposit is penetrated by vertical shafts. Preparation of the productive formation for hydrocarbon production is carried out by the underground mining and development openings placed below a water-bearing horizon covering the rock above the shale rock of the deposit. Hydrocarbon production is carried out by mining blocks of underground producing wells with horizontal sections protruded in the formation. The producing wells are drilled from underground cells constructed mainly in the mining and development openings. Before complete hydraulic fracturing of the formation small diagnostic hydraulic fracturing of the formation is made in the producing wells of a small diameter, which are drilled mainly from the mining and development openings to the whole thickness of the productive formation transversely to its course. The product of the producing wells is divided in the shaft bottom into shale gas and shale oil. The shale oil is outputted to the surface for further treatment before delivery to consumers. The shale gas is burnt in the boiler of a shaft bottom heat-generating plant to generate water steam or hot water used for the production of electricity or for the purpose of a thermal effect on the productive formation in order to increase intensity and the production rate.

EFFECT: reduced total volume of operations on drilling producing wells while developing shale deposits.
