    Abstract: A cement slurry composition is described as having cement, water, and organic polymer particles. The composition also includes non-ionic surfactants, which may contain ethoxylate groups or contain both ethoxylate groups and propoxylate groups in the hydrophilic part. The non-ionic surfactant acts to disperse the hydrophobic polymeric particles in the slurry, thereby reducing mixing time. The cement slurry composition is prepared and then pumped into the subterranean well and placed in a zone of the subterranean well. Time is then allowed for the cement slurry composition to set and form a solid mass in the zone.

    Abstract translation: 水泥浆组合物被描述为具有水泥，水和有机聚合物颗粒。 组合物还包括非离子表面活性剂，其可以在亲水部分中含有乙氧基化物基团或含有乙氧基化物基团和丙氧基化物基团。 非离子表面活性剂用于将疏水性聚合物颗粒分散在浆料中，从而减少混合时间。 制备水泥浆组合物，然后泵送到地下井中并置于地下井的一个区域中。 然后允许水泥浆料组合物在该区域中固化和形成固体物质。

    Abstract: A self-healing cement for use in wells in which acid gases are injected, stored or extracted, comprises an acid-swelling material. In the event of cement-matrix failure, or bonding failure between the cement/casing interface or the cement/borehole-wall interface, the material swells when contacted by acid gases, including carbon dioxide and hydrogen sulfide. The swelling seals voids in the cement matrix, or along the bonding interfaces, thereby restoring zonal isolation. The acid swelling material may also be used without cement for remedial treatments to restore zonal isolation.

    Abstract translation: 用于在其中注入，储存或提取酸性气体的井中的自愈水泥包括酸溶胀材料。 在水泥基体故障或水泥/套管界面或水泥/井壁界面之间的接合失效的情况下，当酸性气体（包括二氧化碳和硫化氢）接触时，材料会膨胀。 膨胀密封水泥基体中的空隙，或沿着粘合界面，由此恢复区带隔离。 也可以使用酸溶胀材料而不需要水泥来进行补救处理以恢复区域分离。

    Abstract: A tool for geological formation having a borehole includes a housing to be positioned within the borehole and a device carried by the housing and including at least one electrical conductor in a dielectric thermoset material surrounding the at least one electrical conductor. The dielectric thermoset material is formed as a cyanate ester and molecular sieve blended therewith. The molecular sieve in one example is formed from zeolite and in another example is formed as a 5A molecular sieve and in yet another example a 13X molecular sieve.
