True Flow

Keep track of reservoir pressure without stopping production, even behind casing

Knowing reservoir pressure is fundamental to managing well and reservoir performance more effectively. But assessing formation pressure behind casing using traditional techniques can be costly, time consuming and disruptive.

Reservoir Pressure provides formation pressure information behind casing, bringing the critical insights needed without the cost and disruption of more invasive techniques.

Delivered by our True Flow system with Chorus technology and proprietary Polygon modelling code, Reservoir Pressure provides the clarity and insight needed to manage well and reservoir performance more effectively.

Reservoir Pressure has become an invaluable resource for operators managing assets to improve or maintain well and reservoir performance.


Reservior pressure assesses formation pressure behind casing so you can manage well and reservoir performance… more… effictively
