How the length of the wells on the Troll field were extended

The EC-Drill®  Controlled Mud Level system assisted operator in reaching new reserves, prolonging production in depleted Troll field.

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.
