Abstract:
Oil and gas recovery includes selecting a previously used oil or gas containing layer in which cumulative perforation was utilized, closing micro cracks over a thickness of the oil or gas containing layer, carrying out slotting of the oil or gas containing layer to form slots, producing micro cracks over the thickness of the oil or gas containing layer, carrying out hydraulic fracturing of the oil or gas containing layer, and withdrawing oil or gas from the oil or gas containing layer with maintaining of a pressure in the well.

Claim (Index 9):
A method of oil and gas recovery from oil and gas containing layers, comprising the steps of\n selecting a previously explored and used oil or gas containing layer in which cumulative perforation was utilized; closing micro cracks over a thickness of the oil or gas containing layer produced in the oil or gas containing layer as a result of the cumulative perforation with the use of bentonite clay solution; carrying out slotting of the oil or gas containing layer by hydraulic sand-blasting to form corresponding slots in the latter, including 4 slots with a width of 2-10 diameters of the well along a whole height of the oil or gas containing layer; producing micro cracks over the thickness of the oil or gas containing layer, wherein the micro cracks produced over the thickness of the oil or gas containing layer are produced after cutting of slots by actions selected from the group consisting of plasma actions, impulse actions, acoustic actions, applied to the oil or gas containing layers; carrying out hydraulic fracturing of the oil or gas containing layer by a corresponding action; and withdrawing oil or gas from the oil or gas containing layer with maintaining of a pressure in a well through which the oil or gas containing layer is reached and oil or gas is recovered.
