GeoContainment™ Solutions for Salt Caverns

BGES is a leader in subsurface GeoContainment™ services with expertise in logging, field testing, laboratory testing, and simulation.

The concept of GeoContianment™ is important to the design, construction and operation of underground salt caverns, which are commonly used hydrocarbon storage or disposal of toxic materials.  In recent years, caprock failures and salt cavern roof collapses have made subsurface GeoContainment™ critical for public safety, environmental protection and corporate risk management.  As a result, regulatory agencies are implementing increasingly stringent testing and periodic monitoring requirements. BGES combines a multi-disciplinary Geoscience & Engineering team with experienced operations personnel to provide integrated solutions for optimizing and protecting your assets.  We offer a full suite of technical services for the entire lifecycle of a cavern – from initial assessments to cavern abandonment:

Salt & Caprock Core Recovery and Management

A reliable cavern model depends on high-quality input data; high-quality data begins with capturing the core in a manner that preserves virgin rock properties. Because core samples are highly sensitive to aggressive handling, diligent core handling is crucial to ensure lab results that accurately reflect true formation properties. After careful cutting and preserving on location, the core is transported, using a specially-designed and environmentally-controlled trailer, to our geotechnical lab in Calgary for further processing.

Geotechnical Laboratory Testing

Geomechanical testing of salt cores provide critical inputs to a cavern’s numerical model and is required by regulators before the leaching/washing process can begin. BGES is currently the only commercial geomechanical lab in Canada to provide lab testing services for salt caverns and has developed a proprietary process for multi-stress permeability tests on caprock. Our laboratory testing and subsequent modeling program is designed to evaluate three major elements of formation behaviour related to cavern behaviour: Strength, Stiffness, and Creep.

Mechanical Integrity Testing (MIT)

BGES is actively developing new technologies to improve the execution and accuracy of cavern MITs while reducing the associated costs. Our latest patent-pending development is a multi-receiver density interface detection tool with a vertical resolution of up to 2” (or 5 cm) and capable of making continuous measurements of interface level, downhole pressure, and temperature. For more information please see our Integrated Detection Tool (Patent Pending) Page.

Sonar Survey

BGES has formed official exclusive partnership with SOCON to provide high-quality sonar surveys to cavern operators across Canada. SOCON is a world-renowned sonar survey tool and equipment manufacturer. The company was established in 1991 in Germany and has remained as a specialist in high-quality sonar surveillance of underground caverns since.

Logging

BGES is highly skilled in conducting logs for evaluating casing and cement integrity, determining fluid interface and locating cavern elements, etc. in high-pressure caverns. With over 20 years of experience in wireline services, we are dedicated to helping customers with any complex wireline projects in the most challenging environments. We take pride in being a one-stop-shop for a wide spectrum of logging needs; we believe that a streamlined approach provides optimal results.

Project Management / Technical Reviews

BGES’ project management/technical review services provide cost-effective solutions and valuable technical inputs for cavern design, development, operations, regulatory compliance, and end-of-life risk management. Our participation in due diligence / cold eyes review undertakings will provide key decision-supporting metrics for new projects, M&A reviews, and other business needs.
