Halliburton JV Completes Coiled Tubing Work at Sakhalin-1

Halliburton's Energy Service Group and joint venture partner OAO "NK" Rosneft - Sakhalinmorneftegaz (SMNG) have successfully completed coiled tubing perforating work for Exxon Neftegas Limited (ENL), operator of the Sakhalin-1 project, located off the northeast coast of the Sakhalin Island in the Russian Far East, setting several world records in the process.

A team composed of ENL engineers and Halliburton and SMNG personnel achieved a maximum measured depth of 30,604 feet (9,328 meters), setting a world record run of a continuous length of coiled tubing. A new hydraulic tractor device was used to deploy the coiled tubing that was in turn used to convey the necessary bottom hole assemblies needed to perform perforating operations.

The coiled tubing conveyed perforating operation was conducted independently of the drilling rig, allowing the rig to continue with the drilling program. The procedure helps reduce overall cost and helps to accelerate the drilling and completion schedule through simultaneous operations.
