摘要： Viscoelastic surfactant (VES) gelled aqueous fluids containing water, a VES, an internal breaker, a VES stabilizer, a fluid loss control agent and a viscosity enhancer are useful as treating fluids and particularly as fracturing fluids for subterranean formations. These VES-based fluids have faster and more complete clean-up than polymer-based fracturing fluids. The use of an internal breaker permits ready removal of the unique VES micelle based pseudo- filter cake with several advantages including reducing the typical VES loading and total fluid volume since more VES fluid stays within the fracture, generating a more optimum fracture geometry for enhanced reservoir productivity, and treating reservoirs with permeability above the present VES limit of approximately 400 md to at least 2000 md.
摘要翻译：粘弹性表面活性剂（VES）胶凝含水的含水流体，VES，内部破碎剂，VES稳定剂，流体损失控制剂和粘度增强剂可用作处理流体，特别是用于地下地层的压裂流体。这些基于VES的流体比基于聚合物的压裂液具有更快和更完整的清理。内部破碎机的使用允许准备移除独特的基于VES胶束的假滤饼，其具有若干优点，包括降低典型的VES载荷和总流体体积，因为更多的VES流体停留在裂缝内，为增强的储层产生更优化的裂缝几何形状生产力，并处理渗透率高于目前VES极限约400 md至2000 md的油藏。

摘要： The migration of coal fines within a bed is reduced, inhibited or constrained by contacting the fines with nanoparticles, such as magnesium oxide crystals having an average particle size of about 30 nm. These nanoparticles may coat a proppant during the fracturing of a subterranean formation to produce methane from a coal bed therein. The nanoparticles may also treat a proppant pack in a fractured coal bed. The nanoparticles cause the coal fines to thus bind to or associate with the proppants. Thus, most of the coal fines entering fractures away from the near-wellbore region will be restrained or controlled near their origin or source and the production of methane at a desired ievei will be maintained much longer than a similar situation than where the nanoparticies are not used.

摘要： An aqueous, viscoelastic fluid gelled with a viscosifier, e.g. a viscoelastic surfactant, is stabilized and improved with an effective amount of a particulate additive such as alkaline earth metal oxides, alkaline earth metal hydroxides, transition metal oxides, transition metal hydroxides, post- transition metal oxides, and post-transition metal hydroxides. These fluids are more stable and have a reduced or no tendency to precipitate, particularly at elevated temperatures, and may also help control fluid loss. These particulate additives have unique particle charges that use chemisorption, "crosslinking" and/or other chemistries to associate and stabilize the VES fluids, and also help trap or fixate formation fines when placed in a gravel pack or a proppant pack in a fracture. Some of these effects may be more pronounced the smaller the size of the particulate additive.

摘要： Emulsified acids have been used to increase production rates of oil and gas in carbonate reservoirs through acid fracturing and matrix acidizing operations. An emulsifier is used to emulsify the aqueous acid with an oil, usually diesel. Very small particles, such as colloidal clay particles and/or nanoparticles increase the stability of the emulsified acids over an elevated temperature range.

摘要： Compositions including relatively low reactivity acids, mixed with viscoelastic surfactants (VESs) and internal! breakers may serve as drill-in fluids to open underground hydrocarbon reservoirs with carbonate contents of 10 wt% or above. The drill-in fluids have low viscosities in the drilling pipe. After the fluid flows out of the drill bit, the acids react with carbonates in the formation thereby increasing the pH of the drill-in fluids causing the VES to gel the fluid at the bottom of the hole and the downhole annulus between the drilling pipe and the formation rock. The viscosified drill-in fluid will reduce fluid loss and will carry no dissolved drilling debris to the surface. After drilling through the targeted formation, the internal breakers in the viscosified drill-in fluids will break down the fluids to permit their removal, and the well is ready to produce with very little or no near well bore damage.
摘要翻译：组合物包括相对低反应性的酸，与粘弹性表面活性剂（VES）混合，内部！破碎机可以用作钻入液体以打开碳酸盐含量为10重量％或更高的地下储层。钻孔液在钻井管中具有低粘度。在流体流出钻头之后，酸与地层中的碳酸盐反应，从而增加钻入流体的pH，使得VES将孔底部的流体和钻井管和钻井孔之间的井下环空凝结形成岩石。粘稠钻井液将减少流体损失，并且不会在表面上携带溶解的钻屑。在钻孔通过目标地层后，粘稠钻井液中的内部破碎机将分解流体以允许它们的移除，并且井准备好产生很少或没有接近井眼损坏。

摘要： Water production from a subterranean formation is inhibited or controlled by pumping a fluid containing coated particles through a wellbore into the formation. The particles have been previously coated with a relative permeability modifier (RPM). Upon contact with water, the RPM coating expands or swells and inhibits and controls the production of water. The RPM may be a water hydrolyzable polymer having a weight average molecular weight greater than 100,000. The particles may be conventional proppants or gravel.
