CAN-ductor technology lowers environmental impact of Kathryn well
Pre-rig well construction technology specialist Neodrill has shared the Life Cycle Assessment (LCA) report for its work on Repsol’s Kathryn well in the Norwegian North Sea. The report was carried out by Asplan Viak, a Norwegian engineering consultancy.
The LCA study compared the environmental impact of the well, drilled using the CAN-ductor technology, to that of a conventionally drilled well. The report analysed all aspects of tophole activity, including drilling and supply vessels, energy, and casing materials as well as the production, installation, removal and maintenance operations of the CAN-ductor unit.
The report compared the processes for both the CAN and conventional drilling methods across eight environmental impact categories, including CO2 emissions. It was found that reduced rig time and the decreased volume of materials required by the CAN technology, such as cement and steel in well casings, were the main reasons for its strong environmental credentials.
