How it started

History

JACOS started oil sands activities in the Athabasca area in 1978 on leases held by Petro-Canada, Canadian Occidental (Nexen) and Imperial Oil to form the PCEJ group. It was the first Asian-owned oil company to exploit the Athabasca oil sands. JACOS and its partners experimented with a cyclic steam stimulation (CSS) pilot project on the Hangingstone Lease from 1984 to 1994.

In 1992, JACOS parent company JAPEX participated in the Alberta Oil Sands Technology and Research Authority (AOSTRA) steam-assisted gravity drainage (SAGD) pilot experiments at the underground test facility (UTF) site. With the positive results from the UTF project, JACOS decided to further pursue SAGD technology at the Hangingstone site. A 3-phase demonstration project was designed and constructed with the first phase becoming operational in 1999.

In 2021, JACOS was acquired by Greenfire Resources Operating Corporation (GROC) which is backed by McIntyre Partners and Griffon Partners.
