EPEX 2026
Thank you to everyone who attended, presented, sponsored, exhibited, volunteered, and helped make EPEX 2026 a strong two-day conference and trade show for Ontario's subsurface energy community.
EPEX 2026 took place June 3rd & 4th, 2026 at Best Western Plus Lamplighter Inn & Conference Centre, London, Ontario. Look for announcements on EPEX 2027 in late-summer. To present, suggest a topic, sponsor, exhibit, or provide feedback, share your interest in EPEX 2027.
Why EPEX
A practical conference for subsurface work in Ontario and beyond
Designed for working professionals
EPEX is the forum for anyone looking to share knowledge and network around the activities in Ontario licensed under the Oil, Gas & Salt Resources Act and new Geologic Carbon Storage Act. From exploration, to operations, to plugging.
Themes this year include energy storage (including new horizontal gallery concepts), hydrogen storage, salt mining, well services, well plugging, and legacy wells. Geological, engineering, operating, and policy knowledge was shared.
Built around connection
The program is structured to create space for conversation: focused talk blocks, trade show spotlight sessions, and dedicated networking breaks that make it easier to find collaborators, vendors, and mentors.
Our goal is to connect people with people, resources, knowledge, and business.

Core Workshop: Using the Matt Rine Pinnacle Reef Model to better understand the Petrolia East Oil Reef
Hands-on core + log interpretation
This workshop focused on Silurian pinnacle reef sediments in the Michigan Basin, using a modern reef model (including updated facies nomenclature) and practical subsurface examples to support exploration, development, and storage work.
The session was designed to connect core observations with wireline logs and regional/field-scale cross-sections, so attendees can translate geology into decisions.
Workshop details
Workshop deliverables
The workshop provided a clear geological story, supporting visuals, and a practical reservoir interpretation take-away. Workshop resources will support ongoing education and reference.

Recognizing partners who make EPEX possible
Sponsorship supports the program, keeps costs predictable, and helps us invest in better learning experiences.
If your organization works in subsurface, energy, or geoscience services, sponsorship is also a high-signal way to meet the right people in the room.
Thank you to the 2026 sponsors for supporting the program, attendee experience, and post-conference resources.

FAQ (quick)
Who can attend?
EPEX is open to anyone. Members of the OPI do receive preferred rates.

Is this event technical, or more general?
EPEX is technical and practice-oriented. Sessions are accessible to a broad audience, but the goal is to deliver useful detail, not high-level marketing.
The Trade Show floor is geared to the operational side of your companies.
