Abstract: Compositions comprise polyacrylamide, a non-metallic crosslinker and a pH-adjustment material. Such compositions have utility in the context of remedial cementing, plug cementing in particular. The compositions may be pumped into a subterranean well, where they polymerize and form a support on which a cement plug may sit. The support may maintain the position of the cement plug in the wellbore and minimize cement-plug contamination.
Abstract translation: 组合物包括聚丙烯酰胺，非金属交联剂和pH调节材料。 这种组合物在补救性固井，特别是插塞固井的情况下具有实用性。 可以将组合物泵送到地下井中，在那里它们聚合并形成水泥塞可以放在其上的支撑物。 支撑件可以保持水泥塞在井筒中的位置并且最小化水泥塞污染。

Abstract: A method includes performing a chemical process to create a chemical product and an amount of heat, and transferring the heat to a first fluid. The method further includes hydrating a polymer in the first fluid, and adding the chemical product from the chemical process to the first fluid to create a treatment fluid. The method further includes diluting the treatment fluid with respect to at least one constituent of the treatment fluid. The method includes treating a formation of interest in a wellbore with the treatment fluid. The method includes changing a formulation of the treatment fluid during the treating. The method also includes extending the treating beyond a design amount, or ending the treatment before the design amount and preserving some reagents of the chemical process.
Abstract translation: 一种方法包括执行化学过程以产生化学产品和一定量的热量，并将热量传递给第一流体。 该方法还包括将第一流体中的聚合物水合，并将化学产物从化学过程加入到第一流体中以产生处理流体。 该方法还包括相对于处理流体的至少一种成分稀释处理流体。 该方法包括用处理流体处理在井眼中的感兴趣的形成。 该方法包括在处理期间改变处理液的配方。 该方法还包括将处理延伸超过设计量，或在设计量之前结束处理并保留化学过程的一些试剂。

Abstract: Pumpable process-fluid compositions comprise polyacrylamide, a non-metallic crosslinker and a pH-adjustment material. Such compositions have utility in the context of controlling lost circulation in subterranean wells. Upon entering at least one lost circulation zone, the compositions crosslink, thereby forming a barrier that minimizes or stops fluid flow from the wellbore into the lost circulation zone.

Abstract: Compositions and methods are given for delayed breaking of viscoelastic surfactant gels inside formation pores, particularly for use in hydraulic fracturing. Breaking inside formation pores is accomplished without mechanical intervention or use of a second fluid. Bromate oxidizing agents are used along with selected breaking activators for the bromate breaking compounds. Useful bromate breaking activators include acid-generating breaking activators, oxidizing sulfur containing breaking activators, and reducing agent breaking activators.
