摘要： A method of creating a network of fractures in a reservoir is provided. The method includes designing a desired fracture network system, and determining required in situ stresses to create the desired fracture network within the reservoir. The method further includes designing a layout of wells to alter the in situ stresses within the stress field, and then injecting a fracturing fluid under pressure into the reservoir to create an initial set of fractures within the reservoir. The method also includes monitoring the in situ stresses within the stress field, and modifying the in situ stresses within the stress field. The method then includes injecting a fracturing fluid under pressure into the reservoir in order to expand upon the initial set of fractures and to create the network of fractures. A method for producing hydrocarbons from a subsurface formation is also provided herein, wherein a fracture network is created from a single, deviated wellbore production.
