Assignee:

Halliburton Company - Duncan OK

International Classification:

C04B 735

US Classification:

106 76

Abstract:

A method of preparing a light weight cement composition from sea water. The light weight cement composition is prepared by adding a hydroxide compound to sea water and subsequently adding a hydraulic cement and silicate compound to the sea water. Optionally, a mixture of hydroxide compound and silicate compound may be formed and this mixture can be added to the sea water prior to the addition of hydraulic cement.

Assignee:

Halliburton Company - Duncan OK

International Classification:

C04B 2400
E21B 3314

US Classification:

166293

Abstract:

Cementing compositions having improved fluid loss capabilities for use in oil, gas, water and other well cementing operations are disclosed. Such compositions are comprised of water, hydraulic cement and a fluid-loss additive comprising a graft polymer comprised of a backbone of lignin, lignite, derivatized cellulose and various synthetic polymers selected from the group consisting of polyvinyl alcohol, polyethylene oxide, polypropylene oxide and polyethyleneimine. The grafted pendant groups comprise at least one member selected from the group of homopolymers, copolymers and terpolymers of 2-acrylamido-2-methylpropanesulfonic acid, acrylonitrile, N,N-dimethylacrylamide, acrylic acid, N,N-dialkylaminoethylmethacrylate and their salts. The backbone comprises from about 5 to about 95 percent by weight of the graft polymer, and the pendant groups can comprise from about 5 to about 95 percent by weight of the graft polymer.
