    摘要： Pre-stressed cementing methods involve preparing a cement slurry containing water, inorganic cement, and capsules of an expanding agent. The slurry is placed in an annular region in the well and hardened. Expansion of the set cement is delayed. Water infiltration activates the expanding agent to rupture the capsules and release the expanding agent. The expanding agent reacts to expand the set cement to a state of compression within the annular region. The state of compression can be maintained during changes in casing dimensions from temperature or pressure, mechanical disturbance, or mud contamination. The state of compression in the annular region may be monitored by acoustic impedance measurements.

    摘要： Fluid compositions comprising rigid fibers, flexible fibers and solid plugging particles may effectively control the egress of fluids from a subterranean wellbore into vugs, cracks and fissures in the subterranean formation rock. The compositions may be effective in drilling fluids, cement slurries, gravel packing fluids, acidizing fluids and hydraulic fracturing fluids. Such fluids may also have utility for providing fluid diversion during well stimulation treatments, allowing the stimulation fluid to avoid higher permeability regions in the formation rock and treat the lower permeability regions, thereby improving stimulation results.

    摘要： A method to treat a subterranean formation penetrated by a wellbore, comprising: providing a treatment slurry comprising a carrying fluid, a solid particulate, an agglomerant and an agglomerant aid; injecting the treatment slurry into a fracture to form a mixture of the solid particulate and the agglomerant; and transforming the mixture into areas that are rich in solid particulate and areas that are substantially free of solid particulate. Also disclosed are a composition comprised of the carrying fluid, solid particulate, agglomerant and agglomerant aid, as well as a method of designing a well treatment therewith and a system to form conductive channels in a fracture.
