Canadian Overseas begins Wyoming gas gathering upgrade

Canadian Overseas Petroleum Ltd. has begun installation of a new high-pressure natural gas gathering system for its Barron Flats Shannon (Miscible) oil production unit (BFSU). Right-of-way was cleared and crews mobilized late-April 2023, with all of the system’s 8-in. OD pipe now delivered to site and strung along the right-of-way.

The new system’s 5 miles of pipe are routed through the field’s core, with Phase 1a using 2- and 4-in. pipe to connect seven batteries and service nine of its 34 producing wells. The current, low-pressure gas gathering system will continue to service BFSU’s remaining wells.

The system is designed to capture additional wells with increased pressures as the field miscible flood matures. Canadian Overseas is also converting certain high-productivity oil producing wells to flowing-pumping configuration in conjunction with installation of the new gathering system.

Welding began May 10, with 2,352 ft of pipe laid and welded as of May 23. Construction is expected to take 2-3 months. Work also includes upgrading well sites by installing high-pressure separators and high-pressure fire tubes for each separator.   

Canadian Overseas budgeted Phase 1a at up to $4.5 million, funded by proceeds from a recent convertible bond financing. The company’s production and development operations are focused in Converse and Natrona Counties, Wyo.
