CIS installs North Sea gas well conductors

Offshore staff

GREAT YARMOUTH, UKConductor Installation Services (CIS) has completed its second conductor installation operation over the past year for a North Sea oil and gas operator. 

The program was for a gas development project in UK southern North Sea. CIS installed six 30-in. conductors to form the foundations for six development wells.

In addition, the company provided conductor-running services, handling equipment, and drive shoes to improve driveability.

Following completion of a drive study, CIS crew worked from the jackup Ensco 80 and used a 90 kJ hydraulic hammer to drive all six conductors to total depth on the wellhead platform.

Some were driven 401 ft (122 m) from the rig floor to the conductor toe, reaching a depth of 158 ft (48 m) below the mudline.
