Well Cements

Well cements are used in the production and exploration of oil and gas onshore as well as offshore in deep water wells to depths up to 7,000 feet. A typical well can be thousands of feet deep and less than three feet wide, and is constructed by using a metal casing surrounded by a special cement slurry mix that fills the annulus between the outer face of the tubing and the wall formation of the hole.

 

Given the complexity of the application and its extreme conditions of temperature and pressure, well cements must be carefully designed to meet demanding requirements such as predictable thickening time (set time), high sulfate resistance, high durability, fluid loss control, consistency, low viscosity, low free fluid, and strength.

 

Lafarge Well Cements provide a base ingredient in the slurry mix that is pumped into the interior metal section of the well and forced back toward the surface from the base of the borehole, filling the annulus.

 

Lafarge Well Cements are tested to conform to API Spec 10A requirements. 

 

Lafarge leads the industry in the production of well cements, locally and internationally.

 

Lafarge's plants and distribution centers cover a wide geographic area where oil and gas exploration and production are present. Areas served in North America include the Texas-Louisiana Gulf Coast, Mississippi, Alabama, the Midwest, Alaska, and Western and Eastern Canada.
