Abstract: Rows of horizontal production wells and rows of horizontal injection wells are drilled and alternating in a formation. The horizontal production wellbores and the horizontal injection wellbores are placed in the direction of a minimum horizontal stress in the formation. Within casing strings of the wells, at least two hydraulic frac ports are installed and multi-stage fracturing is performed through them in the production wells and in the injection wells in such way that fractures are formed along each production well and along each injection well in a direction perpendicular to the horizontal wellbore, the hydraulic fractures in the injection wells are offset from the hydraulic fractures in the production wells. The production and the injection wells are put into operation by injecting a fluid into the injection wells, a flow rate and/or a volume of the injected fluid are controlled in such a way that the injection pressure is below a fracturing pressure.

Abstract: A method of tracking a treatment fluid in a subterranean formation penetrated by a wellbore provides for injecting the treatment fluid with the plurality of tracer agents into the well and the formation. The tracer agents are high viscous liquid droplets having a diameter of not more than 1000 nm. Location and distribution of the treatment fluid is determined by detecting changes in physical properties of the formation caused by arrival of the treatment fluid comprising the plurality of the tracer agents.

Abstract: A horizontal well may be refractured or reactivated by generating a geomechanical model to estimate the stress level in the formation; identifying zones with high, medium, and low stress levels in the formation; isolating existing fractures in the horizontal well; injecting a fracturing fluid into the well to create at least one new fracture in a zone with a low stress level and packing the created fracture with proppant to increase the stress level in the zone; isolating the at least one newly created fracture; initiating refracturing in the zone with the high and/or medium stress level; identifying a location of the refracturing crack in the zone with the high and/or medium stress level; and developing the refracturing crack and packing it with proppant.

Abstract: The method for orienting hydraulic fractures in a subterranean formation comprises injecting a first fluid into a first horizontal wellbore penetrating the subterranean formation and open to the formation in at least one specified segment and pressurizing the first fluid in the first wellbore to create a stress field around each specified segment of the first wellbore. A second pressurized fracturing particle-laden fluid is simultaneously injected into a second horizontal wellbore open to the formation in at least one specified segment and vertically spaced apart from the first wellbore for inducing fractures propagating from the specified segments of the second wellbore towards the specified pressurized segments of the first wellbore.
