EC-Drill® Technology
Securing the Integrity of a Section
Securing zonal isolation is critical for a well. Reaching desired depth for the Top of Cement (TOC) requires a good control of the wellbore pressure while cementing.
Why Cementing Can Be Challenging, Expensive and Time-Consuming
Pumping high density, and viscous, cement will easily lead to losses. Remediating a cementing problem is costly and not always successful. Foam cement adds logistics, costs and complexity. Surface Back Pressure can be used but requires displacements and slow tripping speeds before commencing the cement job.

Managed Pressure Cementing Without Flat-Time
Adjusting the Pressure While Cementing
The unique pressure profile with Controlled Mud Level is lower at shallow depths reducing the likelihood of taking losses when controlling and adjusting the pressure ensuring the cement reaches its desired depth.
Reduce Rig Time
Avoid displacements with the Controlled Mud Level. The fluid level is adjusted according to ongoing operations and will improve tripping margins when pulling out and running in, and facilitates higher circulation rates.
Straightforward, Improved and Time-Saving Cement Operations
Control the pressure while cementing. Speed up the cement job with higher flow rates when conditioning and cementing, trip faster and avoid mud displacements.
