摘要： The invention provides a cementitious composition for oilfield application comprising an organic retarder having at least one carboxylate group and copper ions such that a complex is made between copper ion and carboxylate group. Also a method to retard cementitious composition for oilfield application is disclosed, the method comprising the unique double step of adding an organic retarder having at least one carboxylate group and adding copper ions such that a complex is made between copper ion and carboxylate group.

摘要： The following describes a novel and alternative mechanism in regards to releasing reactive chemicals. Namely, utilizing shells containing multiple emulsions that can be blended with the base fluids, and then react with said base fluid upon exposure to a trigger e.g. high shear and/or elongation flow, therefore plugging even large fractures. Such gelling lost circulation material allows to obtain a reliable carrier and fast reaction when triggered.
摘要翻译： 以下描述了释放反应性化学物质的新型和替代机理。 也就是说，利用包含可与基础流体共混的多重乳液的壳，然后在暴露于触发器时与所述基础液体反应。 高剪切和/或伸长流动，因此堵塞甚至大的裂缝。 这种胶凝失去循环材料可以在触发时获得可靠的载体和快速的反应。

摘要： Lipophilic fibers are effective media for cleaning non-aqueous fluids out of a subterranean wellbore. The fibers are preferably added to a drilling fluid, a spacer fluid, a chemical wash, a cement slurry or combinations thereof. Non-aqueous fluids, such as an oil-base mud or a water-in-oil emulsion mud, are attracted to the fibers as they circulate in the wellbore.
