  METHOD FOR NATURAL GAS STORAGE IN SUBSURFACE TANK CONSTRUCTED IN DEEP-FROZEN SOIL
Invention is related to methods of natural gas production and storage in the form of natural gas hydrates (NGH) in the subsurface tank cavern. The method includes preliminary filling of the cavern with salty water-ice mixture (WIM). NGH are received by pressure pumping of natural gas through a suspended casing equipped with a dispergator, its further bubbling through WIM with simultaneous injection of additional WIM to the cavern, performance of low-amplitude vibration of the mixture and extraction of water excess from the suspended casing.

  TREATMENT BY HYDROFINING AND DEWAXING TO UP JET ENGINE FUEL FREEZING POINT
Invention relates to production of fuel for jet engines from kerosene stock. Proposed method comprises hydrofining of kerosene stock with freezing point interval of 163-302C (325-575F) over hydrofining catalyst under conditions of hydrofining. This allows getting hydrofined kerosene stock.

  MULTILAYER OIL DEPOSIT DEVELOPMENT METHOD
Production zones are determined, producing and injection wells are drilled, oil recovery is made through producing wells and working fluid injection is made through injection wells. At that the four following zones are indentified as production zones: two terrigenous and two carbonate zones, at the end of the second stage of oil deposit development when maximum year oil production parameters start decreasing and measures are performed on year-by-year basis starting since the first year of the method implementation.

  METHOD FOR INTEGRATED PROCESSING OF OIL-CONTAINING STOCK
Invention relates to the method for integrated processing of oil-containing stock that lies in stock spraying in vacuum distillation chamber by means of opposite dispergators forming drop-feed flares, evacuation of residual stock and cumulative gaseous phase formed in result of flash distillation, fractioning of cumulative gaseous phase.

  METHOD FOR SEARCHES OF OIL AND GAS DEPOSITS
Invention relates to the field of searches of hydrocarbon deposits. The invention concept is as follows: a number of holes is drilled up to the depth of 1-3 m. Samples of gaseous medium are taken by bubbling through mineralized water and hydrocarbon gases are analysed.

  METHOD AND DEVICE FOR IDENTIFICATION OF HYDROCARBON-BEARING BEDS
Proposed method comprises drilling the wildcat well and recording of data signal from drilling zone. Note here that said data signal represents electromagnetic radiation caused by bed material destruction by drill bit to compare obtained spectrum of signals with premade spectra of destruction of materials containing the known amount of hydrocarbon stock. In case said spectra are alike hydrocarbons are considered available in the bed. Besides, signal originating in drill bit volume is recorded by radio antenna located on the surface while said rill bit is isolated from casing pipe.

  METHOD OF EXTRA-HEAVY OIL AND/OR BITUMEN DEPOSITS DEVELOPMENT WITH HELP OF INCLINED WELLS
Proposed method comprises drilling ascending well section in oil hole with two exposed zones equipped with filters, filtration zone and steam injection zone and bottom located under roof at least 2 m, locating of production string with centralisers in said section for cyclic injection of heat carrier via them and oil string for oil extraction and before lowering said heat insulated string with pump,

  OIL PROSPECTING AND PRODUCTION
Proposed method consists in revealing the oil reservoir by field and geophysical researches, estimating its hydrodynamic activity by repeated geophysical measurements and defining variation of measured parameters in time, and drilling holes directly into said oil strata.

  DEVELOPMENT OF OIL DEPOSITS BY HORIZONTAL WELLS
Proposed method comprises drilling of prospect holes with recovery of cores and filed is developed by drilling horizontal wells. In compliance with this invention, prospect hole drilling in productive interval is performed with oriented recovery of core to define azimuthal direction of minimum stresses in collector bed. Collector bed depth is defined to develop the field by horizontal holes.

  DEVICE FOR TRANSFER OF THICK OIL
Invention relates to oil industry, particularly, to pipeline transportation of thick oil. Proposed device comprises cylindrical case of flow chamber 1 equipped with flow spreader. In compliance with this invention, said flow spreader is composed of swirling chamber 2 accommodating blades 3 made up of a screw or twisted rods.
