Many decommissioned oil and gas wells in British Columbia have not been properly decommissioned, according a report from the province’s auditor general.
In B.C., oil and gas operators are not required to decommission wells and restore well sites unless the BC Oil and Gas Commission (OGC) explicitly orders them to do so to address specific safety or environmental issues on a case-by-case basis.
“We found that gaps in legislation meant that the OGC lacked the regulatory tools to compel operators to decommission and restore well sites in a timely way,” said Carol Bellringer, auditor general.
The number of inactive wells that had not been decommissioned almost doubled – from 3,800 to 7,474 – between 2007 and 2018. The OGC estimated that decommissioning inactive wells and restoring sites will cost operators $3 billion.
When an oil and gas operator is bankrupt or cannot be located, the OGC designates the operator’s site as orphaned and the OGC becomes responsible for the decommissioning and restoration work.
“The Orphan Fund, which is funded through security deposits and a tax on operator’s production, is meant to cover the costs of restoration, but it was short by $16.6 million in 2016 and $13.1 million in 2017,” Bellringer said.
The number of orphan sites increased from 45 to 326 between 2015 and 2018. The OGC anticipates that the number of orphan sites and associated restoration costs will continue to increase.
In 2018, the legislative assembly passed amendments to the Oil and Gas Activities Act to provide the OGC with the authority to require operators to restore sites, as well as giving it greater flexibility to collect and use revenue from operators to restore orphan wells. At the time of this audit, the OGC was developing accompanying regulations that will detail the requirements, including timelines to decommission wells and restore sites.
The oil and gas industry is an important component of B.C.’s economy. The OGC is responsible for regulating oil and gas activities to protect public safety and the environment.
An inactive well is decommissioned by permanently sealing it with cement. To restore a site means remediating any contamination and reclaiming the land to pre-activity conditions.
