Crew is dedicated to responsibly managing freshwater usage wherever possible, across all operations, and thoughtfully managing water disposal to ensure the safety of the environment, wildlife, and local communities.
By aggressively pursuing produced water as a substitution for fresh water in our British Columbia hydraulic fracturing operations, we have realized a 76% decrease in the use of fresh water from 2015 to 2020. In 2020, 80% of completion fluid was recycled or was non-potable water.
Responsible water management is critical to Crew’s environmental performance. To act on this commitment, Crew has appointed a dedicated Water Management Operator to focus on wildlife mitigation, berm integrity, and soil geotechnical parameters and ensure we have adequate water storage to meet our operational needs. Detailed inspections and Point, an online water management and tracking system, are utilized daily to provide real-time access to our daily operations.

of CO2e emissions saved by transporting ~282,000m3 of produced water using a temporary surface pipeline
Moved approximately 282,000m3 of produced water using a temporary surface pipeline which reduced ~18,756 of heavy haul truck trips, 640 tCO2e emissions, and ~175,000km of road travel.
Although there are no licensed water wells in proximity to Crew’s main operating area in B.C., Crew currently undertakes annual sampling and monitoring on stakeholder identified springs for 8 pad sites to ensure the water quality and quantity is maintained in the areas in which we operate.
*Crew utilizes freshwater storage to minimize the need to continuously withdraw fresh water for its hydraulic fracturing operations. As a result, no fresh water has been withdrawn for the last two years
Water Management and Conservation Strategies
Innovative technology forms a meaningful component of our water management strategy.
- Ongoing investigations and trials into industry leading friction reducers that allow higher sand loading concentrations with optimum water placement in completion operations.
- Installation of cameras on all new pads and pads with produced water storage to facilitate remote monitoring of each site.
- Implementation of spoolable temporary surface pipelines for produced water transfer to significantly reduce traffic, spills, and GHG footprint when transferring water during hydraulic fracturing operations.
- Crew maintains an active presence in the Montney Water Operators Group which brings together operators in the region to share ideas, strategies, and water use challenges. This leads to the sharing of produced water between operators, and reducing the reliance on fresh water for fracturing operations.
- Crew actively consults with First Nations communities to ensure freshwater withdrawals are planned outside of hydrologically sensitive areas.
- Crew drilled a water disposal well in West Septimus during the first quarter of 2020 which handles produced water from our West Septimus facility, reducing costs and eliminating 2,800 tonnes of CO2 emissions, the equivalent of 609 cars per year.
- Portable storage and transportation resources along development corridors enable Crew to be flexible in our core operation areas.
- Creating a strategic plan regarding water sources, storage, and sharing opportunities helps reduce a water scarcity risk.
Crew takes an active approach in well design to reduce the risk of water impact from hydraulic fracturing operations and production.
- Crew completes detailed reviews with key personnel prior to drilling and completion operations
- Installation and design of surface casing and conservative set depths to provide a barrier to preserve shallow aquifers
- Recent design improvements to production casing weight and connection specifications, centralization, and cementing to increase safety factors during hydraulic fracturing and production
- During hydraulic fracturing operations Crew develops procedures and utilizes pump trips and pressure relief valves to prevent over pressuring of the casing and wellhead
- Facilities and pipelines are monitored regularly through routine surveillance and automated systems.
- Proactive erosion and corrosion prevention, maintains the longevity of our facilities.
- Produced water storage is monitored daily by a dedicated Water Management Operator for volumes, leaks detection, and wildlife mitigation. Geotechnical and survey work is completed on produced water sites to ensure the integrity of the lease and containment berms.
