Oil and Gas

Domestic and international oil and gas clients in the midstream and downstream markets turn to Geosyntec for engineering and environmental services and for project management. Our engineering staff, scientists, 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, and risk analyses and with 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.


Our site assessment and remediation teams support clients with spill response assessment, regulatory interaction, and remediation. We conduct due diligence, integrity management, and air, waste, construction management, and we offer many other environmental and engineering services. 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 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 (EHS), manage risk, and reduce environmental liabilities to meet their financial and stewardship goals. Our compliance, permitting, and auditing specialists identify compliance obligations and find opportunities to improve.

When clients need to solve complex challenges of occupational safety and industrial hygiene, they turn to us. Addressing such challenges involves anticipating, recognizing, evaluating, and controlling 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 EHS support services help our oil and gas clients to achieve high standards of EHS performance and compliance. We develop and document management systems to identify, prioritise, and manage potential EHS risks using a plan, do, check, act framework to foster continuous programme improvement.
