Halliburton launches lost circulation cementing solution


Halliburton has introduced SentinelCem Pro cement system to help customers address losses while drilling

SentinelCem Pro cement simplifies mixing operations by eliminating the need for pre-hydration of the slurry design and access to high-purity water sources. This feature facilitates more efficient rig operations with the option to direct mix the system on-the-fly or in a batch mixer. The single-sack packaging facilitates storage in offshore and remote locations.

The thixotropic nature of SentinelCem Pro cement allows the system to stay fluid while pumped into lost-circulation zones and to rapidly gel when pumping stops. This feature enables the system to penetrate deep into fractures and vugular formations to mitigate costly drilling fluid loss to the formation. The system’s early compressive strength development enables a quick return to drilling operations.

Portfolio addition

The SentinelCem Pro system is an addition to Halliburton’s lost circulation portfolio, which addresses a wide range of lost circulation issues. Lost circulation is commonly encountered in drilling and cementing operations and can be a costly challenge to overcome. 

“Lost circulation is the main contributor to costly nonproductive time (NPT) in well construction,” said Matt Lang, vice president of Cementing, Halliburton. “SentinelCem Pro cement safely pumps through the bottom-hole-assembly to help customers quickly address lost circulation events and reduce NPT."
