摘要： The present disclosure concerns a cement dispersant for cement compositions wherein the cement dispersant is a polynaphthalene sulfonate salt having a weight average molecular weight of from 2500 g/mol to 3000 g/mol. The cement compositions are of from 10 weight percent to 70 weight percent of a cement precursor based on the total weight of the cement composition, from 5 weight percent to 70 weight percent water based on the total weight of the cement composition, and from 0.001 percent by weight of cement (BWOC) to 1.0 percent BWOC the cement dispersant. The cement dispersant provides improved rheological properties, allowing for good cement dispensing and increased presence of weighting agents.

摘要： Provided is an invert emulsion oil-based drilling fluid composition that may include an invert emulsion of an oil phase and an aqueous phase. The oil phase may include an oleaginous fluid. The composition may include a low-end rheology modifier that is a C-36 dimer diamine dihydrochloride salt. Further provided is a method that may include introducing the invert emulsion oil-based drilling fluid composition into a wellbore.

摘要： Lost circulation material (LCM) compositions may include an epoxy resin, an emulsifier comprising a polyaminated fatty acid, water, a crosslinker, and an optional cementitious and/or weighting agent. These LCM compositions may have a density of from about 63 pounds per cubic foot (pcf) to about 99 pcf and may be capable of being injected through a drill bit of a drill string into a lost circulation zone in wellbores. Corresponding methods of eliminating or reducing lost circulation in a lost circulation zone from a well may include introducing these LCM compositions into the well.
