Canada and Alberta have strong reporting requirements at both the national and the provincial level to ensure responsible development in the natural gas industry and to minimize impacts on air, water and land.
NuVista’s environmental reporting strives to meet or exceed these requirements. As an active member of the Canadian Association of Petroleum Producers (CAPP), NuVista advocates for industry leadership in these areas. NuVista reports annual air emissions that meet reporting thresholds to Environment Canada via the National Pollutant Release Inventory (NPRI) and to Alberta Environment and Sustainable Resources Development (AESRD) via the provincial greenhouse gas (GHG) reporting program. NPRI data is publically accessible on Environment Canada’s website and provincial GHG data is publically accessible on the AEP website. NuVista also follows CAPP Best Management Practice (BMP) for the management of fugitive emissions.
Industry GHG intensity statistics available in the CAPP Responsible Canadian Energy 2014 Progress Report.
Industry GHG intensity statistics are not available for 2014 and 2015.
All emission totals include direct and indirect emissions.
Unplanned releases to air, water, and land are reported to the Alberta Energy Regulator (AER) in accordance with the provincial regulations. NuVista also maintains strict reporting standards that include internal reporting and mitigation of all small unplanned releases that are smaller than provincial reporting thresholds – right down to a single litre.
NuVista has utilized bi-fuel technology at our drilling and completion operations where available. This technology allows diesel engines to utilize cleaner burning natural gas that reduces both air emissions from transportation and combustion and cost for fuel compared to diesel usage. In 2016, NuVista utilized 1,175 103m3 of natural gas in place of diesel to conduct our drilling and completion operations.
All of our Alberta wells and facilities are regularly audited by the Alberta Energy Regulator (AER) which publishes industry-wide reports and data which are available on its website.
* One pipeline oil emulsion release of 366 m3 occurred in 2015 in NuVista’s non-core operations in Northwest Alberta. This release represented 97% of the corporate reportable release volume in 2015. This was a very rare event, has been fully investigated and cleaned up, and key steps have been taken to prevent recurrence.
