20220289887 · 2022-09-15 ·

This document relates to methods for preventing or inhibiting the cracking or explosion of cement in an oil well using cement compositions that contain polyrotaxane additives. The cement compositions containing the polyrotaxane additives exhibit increased resiliency to cracking as compared to the same cement without the polyrotaxane additive.

FRACTURING A FORMATION WITH MORTAR SLURRY

Methods to provide a fractured subterranean formation includes providing a wellbore in the subterranean formation and providing fractures in the subterranean using a mortar slurry configured to accomplish various objectives.
