Abstract: Cement compositions of the present disclosure include a cement precursor, water, and a cement retarder that includes hydrocarboxylic acid derivatives. In particular, the cement compositions include from 10 wt. % to 70 wt. % cement precursor, from 5 wt. % to 70 wt. % water, and from 0.1 percent by weight of cement (BWOC) to 10 percent BWOC cement retarder comprising the hydrocarboxylic acid derivatives. The hydrocarboxylic acid derivatives provide increased thickening time to the cement compositions at downhole temperatures of greater than or equal to 50° C. The present disclosure further includes methods of cementing a wellbore using the cement compositions with the cement retarder comprising the hydrocarboxylic acid derivatives.

Abstract: 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.
