Method of excavation of oil and gas-producting wells

A method of opening oil- and gas productive layers has the steps of cutting of two slots in one plane so as to form a partition of rock between them and so that stresses from surfaces of slots are redistributed onto the partition and create in it additional pressure, and selecting widths of the slot...

Zusammenfassung:	A method of opening oil- and gas productive layers has the steps of cutting of two slots in one plane so as to form a partition of rock between them and so that stresses from surfaces of slots are redistributed onto the partition and create in it additional pressure, and selecting widths of the slots and the partition such that the partition becomes so stressed that it self-destructs, and as a result a single slot is formed with a length which is equal to lengths of both initial slots and the partition.
