Mechanical Engineering

Our priority is providing efficient and economical specifications and design for your facility projects.
We focus on your design and operational requirements to efficiently create a fit for purpose solution.  

Focusing on your specific needs for onshore production facilities and pipeline networks

 LDIS LLC has a multitude of satisfied customers in upstream, midstream, and downstream facility design. Our Mechanical Engineering team is available to assist in the specification and design of your small to large scale production, processing, and pipeline facilities.

 We have the resources required to successfully and safely implement and complete projects from small well pads and interconnects to large scale oil and gas gathering and treating facilities. Our engineering team works closely with our other in-house disciplines, vendors, and contractors to assure equipment is properly selected for the application along with a correct installation design. Our goal is to provide a final fit-for-purpose product that allows for reliable operation, streamlined procurement, construction, and startup on time and within budget.

Upstream & midstream expertise in production facilities and pipelines: equipment specifications, codes, standards, and best practices.

 We work to ensure compliance with applicable codes and that the right equipment is selected for reliable operation.  Our mechanical engineering team has registered professional engineers with extensive experience specifying, evaluating, and procuring equipment for all types of oil and gas related processes and facilities.
