This document relates to methods for improving the tensile and elastic properties of cement of an oil well using cement compositions that contain sliding-ring polymer additives. The cement compositions containing the sliding-ring polymer additives exhibit increased stiffness while having a minimum impact on compressive strength, as compared to the same cement without the sliding-ring polymer additive.

In accordance with one or more embodiments of the present disclosure, a drilling fluid may include a base fluid and one or more formaldehyde-based resins. The drilling fluid may further comprise one or more water-insoluble acid catalyst precursors or the reaction products of such water-insoluble acid catalyst precursors. The present disclosure also describes sealed subterranean petroleum formations that include such drilling fluids and methods for sealing subterranean wellbores by utilizing such drilling fluids.

Ceiling tiles and wallboards can be produced with vesicle dedusting agent. For example, a ceiling tile can comprise: a dried base mat that includes: (a) mineral wool; (b) binder; (c) a vesicle dedusting agent at about 0.01 to about 10 wt %, wherein the vesicle dedusting agent comprises vesicles; (d) optionally cellulosic fiber; (e) optionally perlite; (f) optionally glass fiber; and (g) optionally calcium sulfate dihydrate. For example, a wallboard produced from a slurry comprising: (a) calcium sulfate hemihydrate at 70 to 95 wt %; (b) a vesicle dedusting agent at about 0.01 to about 10 wt %, wherein the vesicle dedusting agent comprises vesicles; (c) optionally cellulose fibers at about 0.5 to about 3 wt %; (d) optionally at least one dispersant at about 0.01 to about 2 wt %; and (e) water at a ratio of water to dry components of about 1:6 to about 20:1.

A lost circulation material (LCM) is provided having an alkaline nanosilica dispersion and a polyester activator. The alkaline nanosilica dispersion and the polyester activator may form a gelled solid after interaction over a contact period. Methods of lost circulation control using the LCM are also provided.
