Abstract: A method is given for reducing the flow of a treatment fluid in a well, for example for zonal isolation or for stimulation fluid diversion. The method includes preparing a High Solids Content Fluid (a pumpable slurry containing a carrier fluid and a packed volume fraction of at least 50 per cent solids having a multi-model size distribution), injecting the high solids content fluid into the well, placing the high solids content fluid at the location at which fluid flow is to be decreased, and either reducing the volume or increasing the viscosity of the carrier fluid. Optionally, at least a portion of the solids in the High Solids Content Fluid is subsequently removable to restore fluid flow.

Abstract: 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.

Abstract: 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.
