Casing means a pipe or tubing of appropriate material, of varying diameter and weight, lowered into a borehole during or after drilling in order to support the sides of the hole and thus prevent the walls from caving, to prevent loss of drilling mud into porous ground, or to prevent water, gas, or other fluid from entering or leaving the hole.
Casing means pipe or tubing constructed of materials and having dimensions and weights as specified in the rules of this Subchapter, that is installed in a borehole during or after completion of the borehole to support the side of the hole and thereby prevent caving, to allow completion of a well, to prevent formation material from entering the well, to prevent the loss of drilling fluids into permeable formations, and to prevent entry of contamination.
Casing means a pipe or tubing of varying diameter and weight, which is installed into a well to maintain the structural integrity of that well.

More Definitions of Casing
Casing means a watertight pipe which is installed in an excavated or drilled hole, temporarily or permanently, to maintain the sidewalls of the hole against caving, advance the borehole, or, in conjunction with cementing and/or bentonite grouting, confine the ground waters to their respective zones of origin and prevent surface contaminant infiltration. [Amended June 12, 2012]
Casing means the tubular material used to shut off or exclude a stratum or strata other than the source bed and conduct water from only the source bed to the surface.
Casing means a larger pipe enclosing a carrier.
Casing means a tubular watertight structure installed in the excavated or drilled hole to maintain the well opening and, along with cementing, to confine the groundwaters to their zones of origin and prevent the entrance of surface pollutants.
Casing means pipe placed in a wellbore to provide hole stability, isolate and protect groundwater, enhance wellbore integrity, isolate oil and gas formations, and provide pressure integrity.
Casing means a metal pipe or tube used as a lining for oil or gas wells to prevent collapse of the well-bore.
Casing means an oversize load-bearing pipe, conduit, duct, or structure through which a carrier or cable is inserted.
