	Method of development of oil deposit Method includes the determination of the porosity and permeability characteristics of the productive formation, determination of correlation of the value of bottom hole pressure of injection and formation pressure with the porosity and permeability, determination of intervals of optimum injection and formation pressures, equipping of each injection and production well with sensors of bottom-hole pressure, at least once a day measurement of bottom hole pressures in all wells and calculation of formation pressure near wells, stop of injection and withdrawal and/or by variation of modes of operations of wells, maintaining in the formation optimum (from the point of view of the maximum oil recovery) formation pressure, injection of a working agent through injection wells and withdrawal of formation production through output wells in modes of filtering applicable to optimum values of injection, and formation pressures between the injection and withdrawal zones. According to the invention the output wells, the water cuttings of well production of which during last two months has increased by 5% and more, are selected. The selected wells are grouped by presence of the centres of watering, coefficient mutual influence of wells, relative position of wells and sections. The selected sections are ranked by priorities of significant deflection of performance wells from optimum one, significant residual stocks or early stage of development, decrease of capital investment for support of offered modes of operations of wells. In the selected wells first of all the measures on decrease of water content and maintaining in the formation of optimum (from the point of view of the maximum oil recovery) formation pressure are performed. Meanwhile the coefficient of mutual influence of wells is determined empirically by variation of pressure gradient in output wells by means of variation of volumes of compensation through the agent injection into injection wells - from maximum volumes for sandy producing formations up to the minimum volumes for clay producing formations. For top priority measures the site with the compensation parameters 110% is selected.

	Method for multiple hydraulic fracturing of formation in horizontal shaft of well Invention is related to oil industry and may be used for multiple hydraulic fracturing of the formation in horizontal shaft of a well. The method includes running in of a packer to the well on the flow string, performance of hydraulic fracturing in the first interval, formation of proppant plug, performance of hydraulic fracturing in the second interval. In order to obtain screening proppant plug concentration of the injected proppant is increased sharply up to 1100 kg/m³ and injection is stopped artificially due to increase of hydraulic resistance. The volume of injected mixture with increased concentration is calculated with consideration of filter part coverage in the first interval upon destruction of the cross-linked gel and complete settlement of proppant in the well bore. Upon completion of works on hydraulic fracturing in the first area withhold process is made for the period of destruction and complete settlement of unflushed proppant.
