Methods and compositions for cementing are disclosed. Embodiments include a method of cementing comprising: providing a set-delayed cement composition comprising water, pumice, hydrated lime, a primary set retarder, a secondary set retarder; activating the set-delayed cement composition to produce an activated cement composition; introducing the activated cement composition into a subterranean formation; and allowing the activated cement composition to set in the subterranean formation.

Set-delayed cement compositions and methods of using set-delayed cement compositions in subterranean formations. Embodiments include a method of drilling a wellbore in a subterranean formation comprising: circulating a drilling fluid comprising a set-delayed cement composition in the wellbore while drilling the wellbore, wherein the set-delayed cement composition comprises: pumice, hydrated lime, a set retarder, and water. A method of displacing a fluid in a wellbore comprising: introducing a spacer fluid comprising a set-delayed cement composition into a wellbore such that the spacer fluid displaces one or more prior fluids from the wellbore, and wherein the set-delayed cement composition comprises: pumice, hydrated lime, a set retarder, and water.

A method of servicing a wellbore penetrating a subterranean formation, comprising placing a wellbore servicing fluid (WSF) into the wellbore proximate a permeable zone having an average fracture width of about W microns, wherein the WSF comprises a particulate blend and water, and wherein the particulate blend comprises (a) a type A particulate material characterized by a weight average particle size of equal to or greater than about W/3 microns, and (b) a type B particulate material characterized by a weight average particle size of less than about W/3 microns, wherein a weight ratio of the type A particulate material to the type B particulate material is from about 0.05 to about 5.

High efficiency radiation-induced triggering for set-on-command compositions and methods of use

Номер: GB0002547606A
Автор: SAMUEL J LEWIS [US], SAMUEL J LEWIS, Samuel J Lewis
Принадлежит:

Systems and methods that produce bremsstrahlung radiation may facilitate the setting of a settable composition. For example, a method may include providing a settable composition in a portion of a wellbore penetrating a subterranean formation, a portion of the subterranean formation, or both; conveying an electron accelerator tool along the wellbore proximal to the settable composition; producing an electron beam in the electron accelerator tool with a trajectory that impinges a converter material, thereby converting the electron beam to bremsstrahlung photons; manipulating the trajectory of the electron beam in a radial direction, an axial direction, or both of the wellbore with a rastoring device of the electron accelerator tool; and irradiating the settable composition with the bremsstrahlung photons.
