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 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.
