摘要： In one embodiment, a system includes a cased wellbore disposed in a formation of interest. The system includes an emulsion positioned in the wellbore at a depth of the formation of interest. The emulsion includes an oil external phase and an aqueous internal phase. The oil external phase includes particles having calcium hydroxide. The aqueous internal phase includes insoluble silica particles. The system further includes a perforating tool that generates perforation tunnels through the cased wellbore into the formation of interest. The system further includes a well flow control device that shuts in the wellbore for a specified period of time. The emulsion breaks during contact with the formation in the perforation tunnels, and the calcium hydroxide and silica particles form a cementitious material that consolidates the perforation tunnels.

摘要： This invention relates to compositions and methods for treating subterranean formations, in particular, oilfield stimulation compositions and methods using water-in-water polymer emulsions to uniformly dissolve a rheologically active polymer, such as a thickener or friction reducer, in the treatment fluid. The emulsions have a low viscosity and are easily pumped for mixing into a treatment fluid, where upon dilution with an aqueous medium, the polymer is easily hydrated without forming fish-eyes. The partitioning agent in the water-in-water emulsion does not generally affect the rheology of the treatment fluid. The invention also relates to further processing of the emulsion by wet grinding, high shear mixing and/or heating to enhance the hydration rate in the preparation of the well treatment fluid.
