About

BGES specializes in subsurface evaluation for Carbon Capture, Utilization & Storage (CCUS), ensuring the safe and effective containment of CO₂ in geological formations such as saline aquifers, depleted oil & gas reservoirs, and salt caverns. Our services cover the full CCUS project lifecycle, from initial site screening and selection to advanced geotechnical lab testing, in-situ reservoir evaluations, injectivity assessments, and numerical modeling.

A critical component of our work is geocontainment assessment, where we analyze caprock integrity, identify potential leakage pathways, and evaluate reservoir conditions to confirm long-term storage stability. Our injectivity testing provides valuable insights into subsurface characteristics, fluid mobility, and formation heterogeneities, supporting accurate reservoir modeling and optimization. In our geotechnical lab, we conduct specialized tests such as triaxial analyses, porosity, permeability, capillary pressure, and CO₂ core floods to determine rock physical and mechanical properties.

Through flow and geomechanical modeling, we predict how CO₂ injection impacts in-situ stress conditions, ensuring long-term containment and minimizing risks. By integrating multidisciplinary geoscience and engineering expertise, BGES delivers cost-effective, customized solutions that help operators navigate regulatory requirements, optimize storage capacity, and enhance project efficiency.

With a strong track record in subsurface evaluations and recognized industry leadership, BGES is a trusted partner in advancing CCUS initiatives, supporting global efforts to reduce carbon emissions and combat climate change.
