摘要： 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.

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.

摘要： A method for treating a subterranean formation penetrated by a wellbore is provided. The method includes providing a treatment fluid containing a viscoelastic surfactant having at least one degradable linkage, a hydrolysable material, and a pH control material, and injecting the treatment fluid into a subterranean formation. The pH control material may have a pH equal or greater than about 9 and may include a strongly alkaline material and an oxidizing agent.

摘要： In a method of treating a sandstone-containing formation penetrated by a wellbore, a treatment fluid comprising an aqueous fluid containing a Bronsted acid, a hydrogen fluoride source and an organic acid or salt thereof that is substantially soluble in the aqueous fluid is formed. The treatment fluid contains less than about 2% of fluoride (F−) by weight of the fluid and from 2% or less of sodium (Na+) by weight of the fluid. The treatment fluid is introduced into the formation through the wellbore as a single-stage without introducing an acid-containing fluid preflush into the formation prior to introducing the treatment fluid.
