Abstract
Disclosed herein are methods and systems for the transportation and delivery of set-delayed cement compositions to a well site. A method of cementing may comprise preparing a set-delayed cement composition. The method further may comprise storing the set-delayed cement composition. The method further may comprise transporting the set-delayed cement composition to a well site in a containment vessel. The method further may comprise discharging the set-delayed cement composition from the containment vessel and into a wellbore.
Claims18
A method of cementing in a subterranean formation comprising:
- preparing a set-delayed cement composition in a containment vessel, wherein the containment vessel is portable and comprises:
- a mixing chamber for holding the set-delayed cement composition, the mixing chamber being defined by a shell;
- and a shaft holding one or more mixing blades in the mixing chamber;
- storing the set-delayed cement composition in the containment vessel;
- transporting the set-delayed cement composition to a well site in the containment vessel;
- and
- discharging the set-delayed cement composition from the containment vessel and into a wellbore.
A cementing system comprising:
- a discharge vessel for holding and/or mixing a set-delayed cement composition, wherein the discharge vessel comprises:
- a mixing chamber for holding the set-delayed cement composition, the mixing chamber being defined by a shell;
- and a shaft holding one or more mixing blades in the mixing chamber;
- an accelerant vessel coupled to the discharge vessel for holding and/or mixing a cement set accelerator;
- and
- a downhole pump coupled to the discharge vessel for delivering the set-delayed cement composition from the discharge vessel into a wellbore.
