Coretrax Deploys Expandable Drilling Liner in Norway

Global well integrity and production optimisation leader Coretrax has marked a significant milestone with the first deployment of its expandable liner

Global well integrity and production optimisation leader Coretrax has marked a significant milestone with the first deployment of its expandable liner technology in Norway since acquiring Mohawk Energy. The move has allowed the business to deliver and deploy novel technology and specialist personnel from local bases, significantly reducing the logistics, cost, and carbon footprint of travelling from the US. The RelineDL is a hydraulic expansion system which enables operators to isolate low pressure or thief zones which can be encountered while drilling. This provides a significant inner diameter (ID) advantage when compared to a conventional liner string, enabling the safe and effective passage of larger completion strings and maximising production.

Planned and supported from Aberdeen, the expandable drilling liner was mobilised when a major Norwegian operator needed to isolate the gas cap in a lateral well during a drilling campaign.

Compared to conventional methods, the tool enabled the operator to kick-off much deeper in the well, eliminating the need to drill a section of the wellbore and install a tie back. The system was fully expanded within six hours and the entire project was completed in less than 40 hours. This saved 14 days rig-time and delivered significant project efficiencies.

The RelineDL system also provides the operator the option of adding a casing string in either planned or contingency scenarios with minimum loss of wellbore diameter.

Coretrax acquired expandable tubular well specialist Mohawk Energy in May 2019 and Churchill Drilling Tools in November 2019.
