Overcoming Losses With
Pressure Management

Instantaneous Management of Losses

Conventional approaches to managing lost circulation, such as adjusting density or using lost circulation materials (LCM), involve delays and added costs. EC-Drill® transforms this process by enabling rapid adjustments to the bottom hole pressure as soon as losses are detected, giving immediate and effective response without the need for extensive and time-consuming remedial actions. With Controlled Mud Cap Drilling there is also a solution for total loss zones.

Controlling and Stopping Losses

When losses occur, the hydrostatic pressure is adjusted to stop or minimize the losses. Lowering the riser level enables reducing the pressure below what would otherwise be obtainable. 

Controlled Mud Cap Drilling for Total Loss Zones

Total loss zones such as karstified formations can be addressed with continued circulation in the annulus from boost and topfill pumps while returning excess volume to surface. Have complete volume control and continuous monitoring of the annulus while pumping sacrificial fluid down the drillstring.
