Tengizchevroil Adopts Tenaris´ Dopeless® Technology for Projects in Kazakhstan

Tengizchevroil, a joint venture between Chevron, KazMunaiGas, ExxonMobil and LukArco, has chosen TenarisHydril ER™ connections with Dopeless® technology on 13 3/8” casing for its developments in the Tengiz field in Western Kazakhstan

The company decided to migrate from API BTC connections to ER™ Dopeless®connections due to the operational benefits, especially the simplicity of pipe installation. A dry multifunctional coating, Dopeless® technology is applied in a fully automatic process at Tenaris mills worldwide, making thread compounds obsolete. The industrial process guarantees that the exact amount of lubricant is applied to each connection. In standard E&P operations thread compounds are applied manually in the field with a brush.

“Many of Tengizchevroil’s operations take place in extreme cold climates and in remote locations,” said Samat Kulchikov, Tenaris Technical Sales, Kazakhstan. “Dope freezes in sub-zero temperatures making pipe preparation and running difficult. With Dopeless® technology, running operations become simpler, safer and more efficient.”

Customer and Tenaris data collected worldwide has demonstrated that Dopeless® technology can reduce running times in the order of 25%, saving time and money. For example, in another cold weather project –which took place in Eastern Siberia-, Dopeless® technology achieved 27% running time gains in comparison with doped connections.

By taking the dope out of operations, Dopeless® technology also eliminates the possibility of messy make-ups that can cause accidents at the rig site, increasing HSE performance and minimizing the environmental footprint.
