Cement and Casing

"Take an energy excursion to understand the importance of cement and casing to maintaining wellbore integrity as part of the construction of a well."


This lesson discusses how engineers construct a well using steel pipe, called casing. To secure the casing and maintain the integrity of the well, engineers must cement different lengths of casing within the wellbore. Motivation is to recognize that the details of cement and casing are critical to maintaining health, safety and the environment during drilling operations. The lesson on “Cement and Casing” provides foundational knowledge and skills needed to complete the “Design Challenge” lesson in this course.
