We believe in applying science to prevent safety, environmental and financial disasters. In recent years the number of caprock failures in the oil sands and collapses in salt caverns has made subsurface reservoir GeoContainment™ critical for public safety and environmental protection. The science for reservoir GeoContainment™ exists but is often challenging to apply and implement in the oilfield environment. BGES specializes in bridging the implementation gap by having an expert multi-disciplinary team working with in-house operations resulting as a complete GeoContainment™ solution provider.
