Casing Specification &Benefits 

Casing can represent a big percentage of the overall well cost. This makes material grade, size, and connector selection not only an engineering consideration, but an economic one as well.

Casing pipe is available in large diameters that are designed aid the borehole in withstanding forces and chemically aggressive brines. It is typically made from carbon steel, which gets its strength through a heat treating process. Casing can also be specially fabricated using aluminum, stainless steel, titanium, and other materials. Once the casing is assembled and inserted into a freshly drilled section of a wellbore it must be held in place using cement.

Casing adds several beneficial functions to the drilling process:

· Stabilization of upper formations preventing cave-in.

· Stopping contamination from reaching fresh water well zones.

· Providing zonal isolation for sections with different fluids or pressures to prevent blowouts.

· Increasing strength of upper foundation, allowing for use of high-density drilling fluid and deeper drilling.

· Prevention of fluid loss into production zones.
