ExxonMobil, XTO and Pioneer, together have used Tomax technology for more wells than any other operator. As a result, we were invited to contribute to a display in the foyer of the Remote Operation Center (ROC) – part of the new ExxonMobil global headquarters just north from Houston.

Significant step improvement in Plug and Abandonment
Adriatic Sea
Big P&A Savings Repeated
NSC of Italy has repeated a significant step improvement in Plug and Abandonment by completing preparations for cementing in one trip using the latest generation technology from Wellbore Integrity and Tomax.
The string consisted of the Wellbore Integrity 5500 ProMILL for bridge plug setting, section milling and underreaming in one trip. This combo then had the latest generation Tomax XC-AST made up on top the same way as in open-hole drilling and under-reaming. The milling progress was very fast and revealed a big efficiency gain that was confirmed by a corresponding reduction in vibration. The latter was key to keep all tools in the BHA safe and ready for subsequent operations.

tool sizes
Use of the AST requires no changes to standard drilling practices. Each size has a wide working range which covers all practical drilling parameters including operation with Under-Reamers. Special TT-AST tools are available for Thru Tubing services.
Functional Principle
The Tomax AST is a high-performance mechanical-hydraulic converter integrated into the lower drill string. It is engineered to neutralize the root causes of drilling instability, ensuring maximum efficiency in any well.
Preventing inefficiency and destructive vibrations
Most drilling dysfunctions begin when the forces acting on the bit become cyclic. Without intervention, these oscillations increase in amplitude, leading to slow progress, wear and premature tool failure. The AST regulator is specifically optimized to intercept this process by providing a controlled decoupling of Weight on Bit (WOB) from torque.
Adaptive stability technology
The AST mechanical algorithm, or pre-defined response curve, is optimized from mathematical moddelling to continuously optimize the force field at the cutting interface. This makes the AST provide for optimized ROP with any bit and input parameter.
