Shelf zone of the World ocean are highly promising regions of oil and gas. In the Northern part of the Caspian sea conducted geological and geophysical studies, which indicate uplift with the presence of multilayer oil and gas deposits, such as deposits: they. Filanovsky, Korchagin, Sarpinsky Shelly, Khvalynsk, etc. With the aim of optimizing operational process, reduce costs and extract the maximum proven reserves of oil and gas companies are increasingly placing emphasis on productive formations opening of multilateral horizontal wells (FHI) drilled several drainage wells (branches) from one main trunk. Oil and gas companies used the opening of layers multilateral horizontal wells to develop several floors of oil or deposits, and to retrieve previously missed reserves with a single main trunk. The technology for drilling multilateral horizontal wells is often the only economically feasible means of developing disparate parts of the reservoir, deposits-satellites, located on the periphery of the main Deposit, and small deposits of limited value stocks.
