Abstract

Official abstract text for this publication.

Methods and systems for the treatment of wells are disclosed. A method for treating a well comprises providing a treatment fluid comprising calcium-aluminate cement, water, and a cement set retarder; and introducing the treatment fluid into a wellbore. A system for treating a well comprises a treatment fluid comprising calcium-aluminate cement, water, and a cement set retarder; a vessel to contain the treatment fluid; a pumping system coupled to the vessel to pump the treatment fluid; and a conduit coupled to the pumping system.

First claim

Opening claim text (preview).

What is claimed is: 1 . A system for treating a well comprising: a treatment fluid comprising calcium-aluminate cement, water, and a cement set retarder; a vessel to contain the treatment fluid; a pumping system coupled to the vessel to pump the treatment fluid; and a conduit coupled to the pumping system. 2 . The system of claim 1 further comprising a storage system for storing the treatment fluid. 3 . The system according of claim 2 further comprising a drilling system for drilling a wellbore. 4 . The system of claim 1 further comprising a treatment fluid recovery system for recovering at least a portion of the treatment fluid from a wellbore. 5 . The system of claim 1 wherein the cement set retarder is selected from the group consisting of hydroxycarboxylic acids or their respective salts, boric acid or its respective salt, and any combination thereof. 6 . The system of claim 1 wherein the treatment fluid further comprises a cement set activator selected from the group consisting of Groups IA and IIA hydroxides; alkaline aluminates; Portland cement, and combinations thereof. 7 . The system of claim 1 wherein the treatment fluid further comprises a dispersant selected from the group consisting of sulfonated-formaldehyde-based dispersant, a polycarboxylated ether dispersant, and any combination thereof. 8 . The system of claim 1 wherein the treatment fluid further comprises a cement set accelerator selected from the group consisting of lithium sulfate, lithium carbonate, and any combination thereof.
