For more than 25 years, Petra Consultants has provided Engineering, Design, Regulatory, Project Management, and Construction Management services to energy producers.

At Petra, we focus on value driven services, scaling our services to meet the specific needs of our customers, which in turn, makes facilities safer, more efficient, and more cost effective throughout their life cycle.

Petra has a history of work experience offshore in the Gulf of Mexico (GOM) and the North Pacific Ocean and on land in Louisiana, Texas, and Wyoming, designing and installing production facilities from conceptual engineering through commissioning.

Our offshore work history encompasses new GOM shelf structures and pipelines, along with maintenance and major upgrades to both process and structural components of fixed and floating deep-water production facilities. Our onshore projects have ranged from single well facilities to large multi-lease central processing facilities and gathering pipeline systems capable of handling hundreds of wells.


Petra Consultants was founded in 1996 by Mike Trahan. During the past 25-plus years, Petra Consultants has grown from a small, three-person company, to an engineering, design, regulatory, project management, and construction management firm specializing in meeting the facility, topsides, and pipeline needs of the energy industry.
