摘要: Compositions containing an alkali swelling polymer and a pH buffer with a pH between 3 and 7 may be used to treat a wellbore. The pH buffer prevents the swelling of the alkali swellable polymer. The compositions may be placed in the wellbore, whereupon they contact another material with pH increasing properties. The pH of the compositions increases, causing the compositions to swell and form a seal. The alkali swelling polymer may be an alkali swelling latex.

摘要: A permeable cement composition including an aqueous slurry of a hydraulic cement which is based upon a water-immiscible dispersed fluid phase and a hollow particulate material. The hollow particulate material breaks down in the presence of the cement so as to leave voids which together with the dispersed phase create a permeable structure in the cement.

The hollow element can be an additional component added to the cement composition, this component is made of hollow spherical or quasi spherical particles as cenospheres, sodium-calcium-borosilicate glass, silica-alumina microspheres, or a combination thereof. Or the hollow element is a spherical or quasi spherical void made in the set cement, for example by foaming the cement composition with a gas as air, nitrogen or a combination thereof. Use of such cement composition in carbon dioxide application is disclosed. Additionally, a method to cement a part of a borehole in presence with carbon dioxide is disclosed, a method to repair a part of a borehole in presence with carbon dioxide is disclosed using the above cement composition and a method to plug a part of a borehole in presence with carbon dioxide is disclosed.
