Oil & Gas

E3 has experience with a wide variety of oil and gas projects and technologies and our professionals are industry leaders in providing comprehensive technical advice to the industry. Our owners' engineering and due diligence services are highly valued for the development, financing, construction, performance testing, and acquisition or divestiture of oil and gas midstream projects including natural gas and crude oil storage, and natural gas gathering, processing, and pipeline projects.

E3's oil and gas team understands that the technical performance, economics, and risks of oil and gas projects cannot be forced to fit within the conventional rules applied to the development and financing of power or other large-scale non-oil and gas projects.
