Introducing Reservoir Group’s latest drilling innovation, TAZ™ Unlimited Activation Circulating Sub.

The TAZ circulating sub delivers in BHA’s with large volumes of drilling fluids, ensuring that a through bore clearance is maintained through the tool at all times.

TAZ outperforms standard circulating subs when pumping large volumes of drilling fluid due to its unlimited number of activations downhole. It remains dormant in the BHA until opened by a drop ball from surface. The TAZ ball is a patented technology designed to disappear completely, ensuring that a through bore clearance is maintained through the tool at all times.

Engineered, Designed, and Manufactured for Superior Performance:

• Unlimited activations reduce tripping time with no need to POOH to empty catcher sub.
• It’s no pass though restrictions design enables access to tools through the ID lower in the BHA.
• Tools come pre-configured, so the rig crew can easily run the tool.
• With its interchangeable seats and ball sizes, you can run more than one tool in the BHA—creating endless possibilities for hole cleaning applications.
