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.

Method of increasing productivity of oil and gas recovery from previously used wells

For increasing productivity of oil, gas and water wells, a horizontal or inclined well is excavated, a plurality of cavities are formed transversely to the direction of elongation of the well so as to provide partitions between them, and hydrocracking is carried out to act on the partitions between the cavities.

Method of increasing productivity of oil, gas, and water wells

A method of increasing productivity and recovery of wells in oil and gas fields includes determining a direction of maximal horizontal stresses, producing at least two wells so that they are spaced from one another in a direction corresponding to the direction of the maximum horizontal stresses, forming in at least one of the wells at least one vertical slot oriented substantially from the at least one well to the other of the wells, and introducing a hydrofracturing fluid at least into the at least one well to produce a hydraulic fracture in direction from the at least one well to the other well.
