The Troll wells in the North Sea are designed as long horizontal MLT wells through a thin sand. Over many years of production, the sand reservoir has become depleted resulting in a lowered fracture gradient, in addition to fault zones that are prone to losses.

## **Mud volume and cost savings **

The EC-Drill® solution reduced mud losses and saved operator the associated cost.

## **Valuable reserves unlocked with EC-Drill® **

The technology used on the field unlocked valuable reserves, reduced mud losses and saved operator the associated costs.
