Tenaris : Maersk Oil & Gas uses TenarisHydril premium connections for HP/HT well

June 27, 2016

Maersk Oil & Gas Norway faced the challenge of drilling the exploratory 6406/6-4S (Tvillingen Sør) well in block PL510, located in the difficult waters of Norway. This offshore exploration well had both high pressure and high temperatures (HP/HT) as well as a potentially sour environment. In addition, the oil and gas company needed to comply with stringent HSE regulations issued by the local government.

Tenaris supplied a full package of premium connections, including the newly designed TenarisHydril Blue® Quick Seal, Blue® Max, and Wedge 623™ connections plus the Wedge 523™ connection, all with Dopeless® technology, a dry multifunctional coating that renders thread compounds obsolete. The products came with added value services, including field services and coordination of accessories production.

As a result, Maersk Oil & Gas conducted a successful operation with outstanding running times, zero rejects and re-makeups due to connection related issues, and full compliance with Norway's environmental and safety standards. In addition, the operator was able to minimize the environmental impact of the operation and promote the safety of the personnel at the rig site.

These results were taken into consideration when Maersk awarded Tenaris a contract to supply casing and related services for another challenging, HP/HT gas development project in the North Sea that will start during 2016.
