Seismicity: natural gas producers take steps to ensure continued safe hydraulic fracturing operations
CALGARY, Aug. 30, 2012 /CNW/ – Canada’s natural gas producers today
indicated support of the BC Oil and Gas Commission’s investigation into
induced seismicity in the Horn River Basin, including its findings and
recommendations for additional seismic monitoring, data collection, and
operator assessments and protocols that will assure continued community
“Seismicity associated with industrial activities is of concern to the
public. Natural gas companies played a key role in providing the OGC
with data to complete this study, we fully support its conclusions and
we are in the process of finalizing operator guidelines and increasing
financial support for more seismic monitoring in the region,” said
Canadian Association of Petroleum Producer President Dave Collyer.
“Continuing our record of no harm to people or structures is paramount,
as is supporting geoscience that can assure landowners and the public
hydraulic fracturing can and will continue safely.”
Micro-seismic activity is a routine and well-documented occurrence
associated with hydraulic fracturing. Both minor seismic events (2 to
3.8 magnitude) and micro-seismic events (less than 2 magnitude) were
recorded between April 2009 and December 2011 by government and
industry seismic sensors in the Horn River.
More than 8,000 high-volume hydraulic fracturing completions have been
performed in B.C. The BC Oil and Gas Commission study concluded a total
of 272 seismic events recorded were “caused by fluid injection during
hydraulic fracturing in proximity to pre-existing faults” and noted
“none of the events caused any injury, property damage or posed any
risk to public safety or the environment.”
Over the past year, Canada’s natural gas industry has announced guiding
principles and practices for hydraulic fracturing. Additional industry
guidelines establishing monitoring protocols and practices to mitigate
induced seismicity will be finalized by natural gas production
companies in the coming weeks.
“The natural gas industry has operated safely for many decades in
Western Canada, and we will always avail ourselves of new scientific
information, seek consistent application of best practices, including
those that reduce and control seismicity, and encourage transparent
performance reporting,” Collyer said.
Industry funding of additional seismic monitoring in the region is also
being finalized in cooperation with Geoscience BC.
Hydraulic fracturing is a highly controlled and engineered process where
water and other fluids are injected at high pressure several thousand
metres below the earth’s surface to crack shale rocks and produce

The Canadian Association of Petroleum Producers (CAPP) represents
companies, large and small, that explore for, develop and produce
natural gas and crude oil throughout Canada. CAPP’s member companies
produce more than 90 per cent of Canada’s natural gas and crude oil.
CAPP’s associate members provide a wide range of services that support
the upstream crude oil and natural gas industry. Together CAPP’s
members and associate members are an important part of a national
industry with revenues of about $100 billion-a-year. CAPP’s mission is
to enhance the economic sustainability of the Canadian upstream
petroleum industry in a safe and environmentally and socially
responsible manner, through constructive engagement and communication
with governments, the public and stakeholders in the communities in
which we operate.
