About Us

Canada’s leading provider of integrated GeoContainment™ evaluation services

Established in 1996 as “Big Guns Perforating & Logging”, BGES underwent a transformation over the last decade, rebranding itself as Big Guns Energy Services (BGES). This name change reflected the company’s diversification of services, transitioning from a conventional oilfield service provider to a technology-driven consulting and testing firm.

As the largest privately-held integrated GeoContainment™ service provider in Canada’s petroleum and mining industries, BGES offers an array of specialized services. These include reservoir and caprock injection testing, geotechnical lab testing, cased-hole logging and perforating, data analysis, numerical modeling and simulation, technical consulting, project management, and proprietary research and development.

Our esteemed clientele consists of major oil and gas producers, midstream companies, and solution mining operators who prioritize safety, environmental protection, ethics, knowledge, and professionalism. At BGES, we strive to deliver high-quality information and employ advanced methodologies, processes, tools, and equipment to achieve exceptional results.

BGES is the recipient of the Inaugural Canada Oil & Gas Awards “Consultancy of the Year”.

The Consultancy of the Year Award recognizes third party business consultancy services provided to the energy industry with the winner selected by a panel of judges consisting of experienced professionals, independent experts and respected industry veterans. One of the judges brilliantly summarized BGES’ achievements in the following remark:

Understanding the movement and preventing unwanted migration of injected fluid into reservoirs helps reduce negative environmental impacts and safety concerns.”
