Tomax AS signs Frame Agreement for the Caspian Sea

During first half of 2010, BP-Baku and Sperry Drilling Services have conducted three comparative tests in different wells using Anti-stall Technology (AST). The results have been consistently positive and an agreement for stocking and service of AST tools from the Halliburton Baku base is now in place.

RAG implements Anti-Stall Technology in Central Europe

Anti-Stall Technology trials was initiated by RAG in 2009 driven by disturbing levels of vibrations from roller-cone bits through conglomerates and marl. From the first run the vibration problem was solved and replaced by an improvement in penetration and bit life. The effect was found to be consistent as the technology was brought on to consecutive wells.  More

Contract for supply of Anti Stall Technology to Petrobras SA

Based on a successfull run record in complex sediments, Petrobras SA has awarded a contract for delivery of Anti Stall Technology to six new wells primarily targeting "sub-salt" reserves. Maintenence and support in Brazil is handled by Smith International.

Subsea TTRD to a new World Record

Semi-submerisble Stena Don drilled P-4 AH in the Smørbukk South segment of the Åsgard field as a sidetrack from the 7" production tubing. A new high-curvarture RSS from Schlumberger was used to build up to lateral before a conventional PowerDrive was run. The 4 3/4" XD-AST was run in the BHA to optimize drilling efficiency on the 3 1/2" DP. The Statoil TTRD team observed the drilling was steady all the way to TD at 5615m (MD) and stated; "torque, stick-slip, buckling and WOB did not impeede drilling". More

Mærsk Oil & Gas drills deep, vertical HPHT well efficiently with AST

Anti-Stall Technology was deployed from the start of the 12 ¼" section in the Luke X-1 exploration well targeting deep Jurasic objectives in the Danish Northsea. Being specialised in hard carbonates, the drilling team made good use of the stable drilling parameters provided by the 9 HB-AST and penetrated the softer overlaying formations as well as the long, hard, limestone intervals of the Cretaceous Group in one fast run. Consequently use of 6 3/4" XB-AST was continued with similar results in the following hole section to TD through hard Jurasic sandstone. The Mærsk drilling Team concluded that the sections had been drilled at good ROP with practically no vibrations.
