Oil and Gas

Domestic and international oil and gas clients in the midstream and downstream markets turn to Geosyntec for engineering, environmental, and project management services. Our engineering staff, scientific practitioners, and subject matter experts provide creative and effective solutions to address project challenges in the natural and built environments.

Geosyntec supports oil and gas companies with onshore and offshore environmental, safety, risk analyses and engineering support. We are experienced with environmental impact analyses and risk and safety reviews, as well as with site selection, planning, remediation, and permitting. We are also experienced with providing due diligence and mergers and acquisitions assistance.


With one of the most experienced pipeline geotechnical hazard analysis teams in the world, a leading risk and hazard review team, and a large pool of environmental permitting experts who specialise in Swedish EPA regulations, we are active in many midstream oil and gas service areas. Our site assessment and remediation team assists clients with spill response assessment, regulatory interaction, and remediation support. We conduct due diligence, integrity management, air, waste, construction management, and offer many other environmental and engineering services. In addition to our work for pipeline clients, we are experienced with environmental, engineering, and risk and hazard analysis at inland and marine bulk storage facilities as well as at separation and compression facilities.


For many years, oil and gas clients at downstream facilities have entrusted us with environmental and engineering services, including at some of the most challenging assessment and remediation projects in the world. Our industry-leading technical teams understand the latest regulatory changes and technologies related to air, water, wastewater, risk management, sustainability, integrity management, and compliance. We help clients to develop new technologies and tools to make better decisions and reduce liabilities. Our information management and environmental management teams partner with clients to develop and improve their environmental and regulatory compliance programs.

We work with our oil and gas clients to improve environmental and health and safety, manage risk, and reduce environmental liabilities—all to meet their financial and stewardship goals. Our compliance, permitting, and auditing specialists proactively identify compliance obligations and opportunities to improve .

When oil and gas clients need to solve complex challenges of occupational safety and industrial hygiene regarding workplace operations, staff comfort and productivity, and occupant health, they turn to us. Addressing such challenges involves the anticipation, recognition, evaluation, and control of known risks and emerging hazards in the workplace. Our practitioners conduct assessments using the sound scientific principles and practices of industrial hygiene, public health, and toxicology.

Our environmental and health & safety (EH&S) support services help our oil and gas clients to achieve high standards of EH&S performance and compliance. We develop documented management systems to identify, prioritise, and manage potential EH&S risks using a plan, do, check, act framework to ensure continuous programme improvement.
