BiSN Wins the Golden Gecko Award for Environmental Excellence

We are honoured to receive the 2025 Department of Mines, Petroleum and Exploration Golden Gecko Award for Environmental Excellence for our submission, “Alternative Means of Compliance using Bismuth-Based Alloys for Well Plug and Abandonment.”

This recognition highlights the contribution of wel-lok™ technology in advancing safe and permanent well abandonment practices, delivering gas tight and long-term environmental protection through bismuth-based sealing.

A special thank you to CODA – Centre of Decommissioning Australia for their continued partnership and support, and congratulations to our BiSN Australia team, whose innovation and dedication have built something truly remarkable in the region.

We are proud of the engineers, technicians, and project teams behind this achievement, and of our growing presence in Australia and the Asia Pacific region as we continue to develop and deliver BiSN technology, create employment opportunities, and set new standards for environmental performance.

Nomination: Alternative means of compliance using Bismuth Based Alloys for well plug and abandonment

BiSN’s wel-lok™ technology directly contributes to long-term environmental protection by delivering permanent gas-tight barriers during the well abandonment process. The barriers prevent future hydrocarbon migration, eliminate potential leak paths and allow operators and regulators to proceed with full land and seabed rehabilitation.

On Thevenard Island the technology was used to seal more than a dozen legacy wells, some over 30 years old, as part of Chevron’s decommissioning program. On Barrow Island, a Class A nature reserve and World Heritage listed area, BiSN tools were deployed during the phased decommissioning of hundreds of inactive wells.
