Answer:
True
Step-by-step explanation:
Casing is routinely cemented to the borehole wall in many drilling operations. Casing refers to the metal pipe that is inserted into the borehole to provide structural support and prevent the collapse of the wellbore. Cement is then pumped into the annular space between the casing and the borehole wall to create a cement sheath. This cementing process helps to secure the casing in place, isolate different formations, and prevent the migration of fluids between the wellbore and surrounding formations.
