Abstract
In a method of evaluation of deposits and opening of productive formations in recovery of oil or gas, a previously drilled well is located and investigated to determine at least one first zone which is not productive for oil or gas extraction and at least one second zone which is productive for oil or gas extraction; the at least one first zone which is not productive for oil or gas extraction is skipped, while hydroslotting is performed in the at least one second zone by making a plurality of slots and thereby producing unloaded regions so as to provide again a flow of oil or gas in the previously drilled well which was not in operation.
