    摘要： Rapid setting plugging compositions comprising oil, clay, magnesium chloride, and magnesium oxide powder are provided for sealing permeable zones in subterranean formations. The invention also relates to methods for using said compositions. The permeable zones may be sealed by passing the plugging composition and water to the subterranean formation. While being exposed to downhole temperatures in a range of from about 0°F to about 500°F, the plugging composition quickly thickens to form a sealing mass that is substantially impermeable to fluid in less than about 1 minute after contacting the water. It then usually develops an effective amount of compressive strength to prevent it from being washed away within a period ranging from about 5 minutes to about 2 hours at temperatures ranging from about 0°F to about 500°F.

    摘要： Shear thickening fluids which comprise a water swellable material (e.g., clay), capable of rapidly forming a paste having a strength of at least 1000 Pa with the aqueous solution employed and present in sufficient concentration to form such a paste a nonaqueous hydrophobic material comprising a hydrocarbon material and a surfactant and/or strengthening agent, and an aqueous solution comprising water and a water swellable/ water soluble polymer, wherein the clay and water-polymer solution are kept separated by an intervening hydrocarbon-surfactant phase. Preferable, the hydrocarbon-surfactant phase (oil phase) encapsulated clay is suspended in a continuous phase comprising the water-polymer phase; however, suspension of clay and separate, discrete water-polymer droplet in a continuous oil phase are also possible as are compositions commonly called "double emulsions", as well as systems which are bicontinuous. The intervening oil phase prevents the interaction between the water-polymer and the clay phases and results in a stable, non-reacting, pumpable composite, until such time as the oil barrier is ruptured by deliberate application of a sufficiently high shear force. Upon such rupture, the materials mix and interact resulting in a semi-rigid high strength paste. Various well control problems such as oil and gas well blowouts can be controlled by use of the above-described composite. The composite is pumped down the well pipe. Upon application of a sufficiently high shear as by exiting the orifices of the drill bit, needed to rupture the oil envelope, the clay and the water-polymer interact, resulting in the formation of the semi-rigid, high strength paste which cures the well control problem, sealing the well circulation thief zone or terminating or preventing a blowout.

    摘要： A diverter fluid includes an aqueous carrier fluid, and a plurality of water-swellable polymer particles having a size of 0.01 to 100,000 micrometers. A method of hydraulically fracturing a subterranean formation penetrated by a reservoir includes injecting a fracturing fluid into the formation at a pressure sufficient to create or enlarge a fracture, injecting a diverter fluid into the formation, and injecting a fracturing fluid into the formation, wherein the flow of the fracturing fluid is impeded by the diverting agent and a surface fracture area of the fracture is increased. A method of controlling the downhole placement of a diverting agent is also disclosed, including injecting a diverter fluid including the diverting agent and an aqueous carrier fluid selected so that the polymer particles are fully swelled after contacting the aqueous carrier fluid for an amount of time sufficient to achieve a desired downhole placement.
