The Role of Cement Plugs in Drilling Cement plugs serve as barriers to fluid movement throughout various stages of drilling. When placed in the wellbore, they isolate sections to avoid mixing fluids and ensure the cement slurry cures correctly. A well-executed cement job can improve well integrity, reduce the risk of leaks, and prevent blowouts, which can lead to expensive repairs or environmental hazards.

A major operator in Malaysia successfully ran and cemented a 7-5/8" liner through a 9-5/8" milled window offshore Sabah using VULCAN's PHAZER™: FLEX centralizer. PHAZER™: FLEX, the industry-leading under-reamed centralizer with its patented flexible blade design, compressed through the restricted ID and expanded back in open hole to provide effective standoff.
