Leveraging Conventional Natural Gas Extraction
Train 1 of the Goldboro LNG facility is drawn from conventional reserves in the Alberta Foothills which would be expected to have a lower environmental impact than shale gas using multi-stage fracking.
According to lifecycle analysis conducted by Natural Resources Canada, conventional gas has slightly lower emissions than shale gas. In addition, there are environmental concerns with fracking, such as the excessive use of fresh water, and difficulties in the management of waste water
Pieridae is primarily a conventional gas producer. In other words, we do not currently use fracking technology. More than 98 per cent of all producing wells in the Foothills, regardless of which company drilled them, did not use fracking. This means the company does not use an excessive amount of water during the initial phase of the drilling process which sets us apart from other companies with large-scale drilling operations in northwestern Alberta and northeastern British Columbia.
In addition to not needing tens of thousands of barrels of fresh water for each well, conventional wells tend to perform better. They provide more gas over the long term and have a smaller environmental footprint as well as substantially lower completion costs.

Pieridae meets all water management legislation for operations at our gas processing and sulphur forming facilities. Our Health, Safety and Environment (HSE) management system is designed to follow relevant legislation and how we meet water use requirements for water use, water returned, monitoring and reporting. Our facilities are licenced under the Water Act and the Environmental Protection and Enhancement Act. Our licences permit us to withdraw and return water at specified volume thresholds, with analytical testing.
Pieridae continuously seeks new ways to lower our water usage, increase our return, and recycle as much water as economically feasible. Most of the water the company uses is for cooling which is then returned to the environment as steam and, ultimately, makes its way back to earth as clean water. Ultimately, our overriding goal is to protect people’s health and the quality of the natural environment by conserving water resources and preventing adverse impacts.
We strive for reductions beyond regulatory requirements as we work to minimize our water use.
Land Management Strategy
Pieridae will continuously strive to strike a balance between land development, reclamation and biodiversity requirements to ensure we minimize the negative impacts and optimize the positive. We will support initiatives that improve our understanding of biodiversity in the areas where we operate — all with the goal of minimizing our environmental footprint.
When Pieridae decides to retire assets, we strive to accelerate restoration of the land back to its original state. Our restoration work in 2020-2021 included the abandonment of seven wells in British Columbia, three wells in Saskatchewan, and plans for the abandonment of two wells in Alberta. Site assessments, monitoring, and reclamation/remediation activities are scaling up, with plans in place for projects that cover over one 80 sites.
Pieridae manages site closure activities, including remedial work, to meet the requirements and timelines of both the Alberta Energy Regulator Area-Based Closure program, the BC Oil & Gas Commission Dormancy and Shutdown Regulation and other commitments.
The company is progressing the reclamation of all licensed sites at various stages of closure. The reclamation activities include Phase I & II site investigations, site remediation, ongoing environmental monitoring, detailed site assessments and reclamation certificate applications. A 2021 site closure budget is in place and restoration activities are underway.
