摘要： Methods of fracturing subterranean zones with less pumping are provided. The methods basically comprise the steps of providing an aqueous fracturing fluid comprised of a brine having a density in the range of from about 9 to about 19 pounds per gallon, pumping the aqueous fracturing fluid into the subterranean zone at a rate and pressure sufficient to fracture the subterranean zone and recovering the aqueous fracturing fluid from the subterranean zone.

摘要： Improved methods and compositions for consolidating proppant in subterranean fractures are provided. In accordance with the methods of the invention, proppant particles coated with a hardenable bisphenol A-epichlorohydrin resin composition are mixed with a gelled liquid fracturing fluid and the fracturing fluid is pumped into a subterranean zone. The fracturing fluid forms one or more fractures in the subterranean zone and deposits the proppant particles coated with the resin composition therein. Thereafter, the hardenable resin composition on the proppant particles is allowed to harden by heat and consolidate the proppant particles into degradation resistant permeable packs. The hardenable bisphenol A-epichlorohydrin resin compositions of the invention are storable for long periods of time before use.

摘要： Compositions useful in the reduction of excessive water in oil and gas wells and other subterranean formations comprises an organosilicon compound and a relative permeability modifier (RPM) macromolecule. The RPM is capable of impeding the production of water. The organosilicon compound is capable of forming a water-soluble silanol by hydrolysis and is preferably either an organosilane halide or organosilane alkoxide. The composition is introduced into the subterranean formation for the purpose of selectively reducing excessive production of aqueous fluids. The composition may be employed in well treatment fluids introduced into production wells or injection wells. The compositions may also be utilized in conjunction with stimulation treatments and with introduction of other well treatment fluids. By introducing the composition into fluid passages of the formation, the water producing zones can be selectively blocked off. Thus, the ability of fluids to flow through the aqueous fluid containing fluid passages is selectively reduced resulting in the reduced production of aqueous fluids while maintaining production of hydrocarbons. Core flow test results show effectiveness at permeability as high as 7.0 Darcy under high rate flow conditions.

摘要： Improved methods of coating dry proppant particles with a hardenable resin composition, suspending the coated proppant particles in a fracturing fluid and consolidating the proppant particles after being placed in fractures into high strength permeable masses are provided. As the fractures are formed, a liquid hardenable resin component is mixed with a liquid hardening agent component to form a hardenable resin composition. The hardenable resin composition is coated onto dry proppant particles conveyed from a source thereof to form resin composition coated proppant particles, and the resin composition coated proppant particles are suspended in the fracturing fluid.

摘要： Methods are presented to induce a screenout during a subterranean formation fracturing or combined fracturing and gravel packing treatment by laying down a filter cake early in the treatment, then injecting proppant slurry, and then while proppant slurry injection continues chemically damaging the filter cake with one or more filter cake degradation agents so that leak-off increases, the concentration of proppant in the fracture increases, and the proppant screens out. The additional use of filter cake degradation agent aids and bridging-promoting materials is included.

摘要： Improved methods and apparatus for completing a subterranean zone penetrated by a wellbore are provided. The improved methods basically comprise the steps of placing a sand screen (e.g., screens, screened pipes, perforated liners, prepacked screens, etc.) in the wellbore adjacent the zone to be completed, positioning an alternate flowpath comprised of a plurality of blank (non-perforated) tube segments which are open at both ends in the annulus between the sand screen and the wellbore, isolating the annulus between the screen and the wellbore in the zone, and injecting particulate material into the annulus between the sand screen and the wellbore and into the zone, whereby the particulate material is uniformly packed into the annulus between the sand screen and the zone. The multiple flow paths are provided via a series of blank tubes (without intermediate openings) with each tube extending only a portion of the length of the zone to be completed. The permeable pack of particulate material formed prevents the migration of formation fines and sand with fluids produced into the wellbore from the unconsolidated zone. If desired, a protective shroud comprised of a perforated liner can be concentrically mounted over the sand screen and the associated multiple flowpaths (e.g., blank tube segments) to protect and centralize the screen. The method is also applicable to placing gravel packs in a cased and perforated well drilled in the zone.
