Oil and Gas Drilling - The Process

Cement is then pumped through the casing and out through the opening at the bottom of the casing. The cement is forced up between the casing and the hole, sealing off the wellbore from the fresh water. Drilling continues vertically, creating a well approximately 6,000 feet (~1,828 m) deep. The depth of the well will vary by region and formation.
