The company specializes in various types of reservoir and caprock injection testing, geotechnical lab testing, cased-hole logging and perforating, data collection and analysis, numerical modelling and simulation, technical consulting, as well as project management. Our key clients are major oil & gas producers, midstream companies, and solution mining operators who value safety and environmental protection, ethical conduct, knowledge, high-quality information and professionalism. Additionally, BGES performs research & development to develop proprietary test methodologies, processes, tools and equipment.
