Abstract
The article discloses the problem of bringing back into operation the wells having been suspended or out of operation, the technical state of which is unknown and the bottom-hole zone of the formation is heavily plugged. To bring the wells back into operation additionally to other technical solutions for a well deconservation it is necessary to recover the gas-dynamic bond of the reservoir with a well. For this it is offered to perform the formation hydraulic fracturing by two-fraction technology.

Abstract
The use of branched-hole wells in old fully developed oilfields permits to increase hydrocarbons production at the expense of involving the undrained areas in development. The most wide experience of multihole wells operation in Russia was gained in oil fields; and in gas fields the construction of such wells was launched in the field Yujno-Russkoye, West Siberia. The gained experience in designing, construction and operation of multihole wells in the Extreme North fields will enable to recommend these designs in the Arctic region conditions including offshore fields.

Abstract
It is emphasized that well-known Darcy and Forchheimer laws of filtration are applicable for modes with low Reynolds numbers. For modes with a wide range of Reynolds numbers it is necessary to apply the Barry-Conway law of filtration. The shortcoming of this law is the inability to build on its basis the analytical mathematical models easy to apply in practice. The approximation models for Barry Conway law eliminating this drawback are offered.
