    摘要： A method is given for diverting injected slickwater in a hydraulic fracturing treatment. The diversion fluid is preferably a substantially proppant free viscous fluid that causes a net pressure increase and plugging of some of the microfractures in the initial fracture system created, which induces formation of supplementary microfractures connected to the initial fracture network and in-creases the contact area with the formation rock. The method generates a greater fracture network complexity and thus a higher contact area with the reservoir during a single treatment cycle.

    摘要： A method of fracturing multiple zones within a wellbore formed in a subterranean formation is carried out by forming flow-through passages in two or more zones within the wellbore that are spaced apart from each other along the wellbore. The flow-through passages are arranged into clusters, where the directions of all flow-through passages, which belong to the same cluster, are aligned within a single plane (cluster plane). At least one cluster of flow-through passages is formed in each zone. The clusters within each zone have characteristics different from those of other zones provided by orienting the cluster planes at different angles relative to principal in-situ stresses and by placing them into different locations along the wellbore in each of the two or more zones. A propellant pre-fracturing treatment is then performed in the two or more zones to create initial fractures (pre-fractures) in each of the two or more zones. The fracturing fluid in the fracturing treatment is provided at a pressure that is above the pre-fracture propagation pressure of one of the two or more zones to facilitate fracturing of said one of the two or more zones. The pressure of the fracturing fluid is below the pre-fracture propagation pressure of any other non-treated zones of the two or more zones. The isolating of the treated zone is then performed. The fracturing process is then repeated for at least one or more non-treated zones of the two or more zones.

    摘要： A method for minimizing the amount of metal crosslinked viscosifier necessary for treating a wellbore with proppant or gravel is given. The method includes using fibers to aid in transporting, suspending and placing proppant or gravel in viscous carrier fluids otherwise having insufficient viscosity to prevent particulate settling. Fibers are given that have properties optimized for proppant transport but degrade after the treatment into degradation products that do not precipitate in the presence of ions in the water such as calcium and magnesium. Crosslinked polymer carrier fluids are identified that are not damaged by contaminants present in the fibers or by degradation products released by premature degradation of the fibers.

    摘要： A method of fracturing multiple zones within a wellbore formed in a subterranean formation is carried out by forming flow-through passages in two or more zones within the wellbore that are spaced apart from each other along the length of a portion of the wellbore. The flow-through passages within each zone have different characteristics provided by orienting the flow-through passages in directions in each of the two or more zones relative to a selected direction to provide differences in fracture initiation pressures within each of the two or more zones. A fracturing fluid is introduced into the wellbore in a fracturing treatment. The fracturing fluid in the fracturing treatment is provided at a pressure that is above the fracture initiation pressure of one of the two or more zones to facilitate fracturing of said one of two or more zones while remaining below the fracture initiation pressure of any other non-fractured zones of the two or more zones. The process is repeated for at least one or more non-fractured zones of the two or more zones.
