摘要： A thixotropic slurry material can be used in a wellbore during a wellbore operation. The wellbore operation can include a drilling operation, a cementing operation, or any other suitable operation that may include injecting a liquid material into the wellbore. The thixotropic slurry material can be a mixture of a cement, a clay mineral, and a suspending agent and can be injected into a wellbore during the wellbore operation.

摘要： A cement slurry including graphene, a cementitious material, and water; the graphene comprises bioderived renewable graphene (BRG). The cement slurry can comprise from about 0.01 to about 20, from about 0.1 to about 15, from about 0.5 to about 5 percent graphene by weight of cementitious material (% graphene bwoc). The cement slurry can have enhanced stability, as evidenced by a uniform density of the slurry and a reduction in free fluid, according to API 10B-2, relative to a same cement slurry absent the graphene.

摘要： The effectiveness of expansive cement systems may be diluted when, during a well cementing operation, commingling takes place between the cement slurry and a spacer fluid, a drilling fluid, or both. Incorporating expansive agents in the spacer fluid or drilling fluid may reduce or negate the loss of expansion at the cement slurry/spacer interface or the cement slurry/drilling fluid interface, thereby promoting zonal isolation throughout the cemented interval.

摘要： A cement slurry includes a set retarder comprising graphene, a cementitious material, and water; the graphene comprises bioderived renewable graphene (BRG). The cement slurry has from about 0.01 to about 20, from about 0.1 to about 15, or from about 0.5 to about 5 percent graphene by weight of cementitious material (% graphene bwoc). The cement slurry has an increased thickening time relative to a same cement slurry absent the graphene.

摘要： Cement slurries are prepared that comprise water, a hydraulic cement and particles of an oil-absorbent material. The particles are present in an amount sufficient to alter a property of a non-aqueous drilling fluid. The cement slurry is placed in a subterranean well, whereupon the slurry contacts residual drilling fluid on casing and formation surfaces. The oil-absorbent material in the cement slurry may reduce the mobility of the drilling fluid, thereby improving zonal isolation. The oil-absorbent material may be a polyolefin block copolymer.

摘要： Methods for cementing. An example method provides a cement composition comprising an aqueous fluid, a cement, and a cement retarder; wherein the cement retarder is a waste residue from a manufacturing process of a sweetener and comprises a sugar concentration of at least 40%, a Brix value of at least 60, a nitrogen-free extract concentration of at least 50%, a total solids concentration of at least 60%, a crude protein concentration less than 10%, a fat concentration less than 5%, a fiber concentration less than 5%, and an ash concentration less than 10%. The method also introduces the cement composition into a wellbore penetrating a subterranean formation and pumps the cement composition to a location within the wellbore, and allows the cement composition to set in the location.
