Located in one of Canada’s major oil-producing regions, the project represents an important step in CNEY’s strategy to expand its North American energy operations and establish a platform integrating oil production, investment, trading and supply chain services.

By combining Canadian energy resources, institutional investment capital and experienced operating teams, we aim to build a scalable energy investment and supply chain platform that can generate new opportunities for long-term growth.”

Going forward, CNEY will continue to evaluate oil and gas opportunities in Canada and across North America, with a focus on projects supported by established infrastructure, stable resource conditions, experienced operators and reliable sales channels.
