Through its patented Anti Stick-slip Tool (AST), Tomax provides a stable, safe drilling environment, free from stick-slip vibrations produced in the process of cutting through problematic underground formations. The suppression of stick-slip vibrations will also release energy for faster rates of penetration (ROP). As a result, the use of AST will always add significant value where the drilling operation faces risk from stick-slip vibrations.
A troublesome formation known to lock-up the cutters and cause twist-offs was to be drilled with under-reamer. An AST was deployed to solve the problem. […]
Drilling, shale, play, unconventional, lateral, Permian, Eagle Ford The drilling of long laterals for unconventional resources which is typical in shale plays, is on the […]
Torque arrestors and other features are added to reduce vibrations and to keep PDC drill bits safe. ROP however suffers. The AST allows for the […]
Deepwater exploration from large drillships is on the rise. These vessels offer great benefits in terms of mobility and capacity but, from a drilling perspective, […]
Objectives The primary objective was to maximise drilling efficiency in the 5 5/8” section through the hard abrasive Lower Fulmar Sandstone. A turbine BHA was […]
Some wells are drilled primarily to retrieve cores. This puts a lot of pressure on the drilling engineers to find methods that moves the recovery […]
High temperature, high pressure wells are always demanding. One obvious challenge is to keep the mud cool. If the mud gets too hot, vital functions […]
The AST saved at least on day on each section drilled compared to previous wells having the same sea conditions. Objective The combination of 7 […]
The campaign needed extensive under-reaming and caused concerns over vibrations and long bit trips. The group of partnering operators went diligently through all available methods […]
