Our main objective is to provide efficient and economical process engineering support for your projects.

 We provide you with a fit-for-purpose solution that combines your standards and preferences and our comprehensive experience designing facilities across diverse industries.  

LDIS LLC has a proven and growing track record of satisfied customers in the upstream, midstream and downstream markets within the oil and gas industry. Our process engineering team consists of experienced individuals who have the know-how to complete projects of all sizes and scopes.  The team has been a part of all aspects of projects, from conceptual through detailed design and into start-up and commissioning.

We work closely with multiple disciplines to ensure a successful project. Our process engineering team has experience in developing design basis documents, process simulations, sizing and specifying equipment, developing PFDs and P&IDs, line sizing, sizing control valves, specifying / sizing /validating Pressure Safety Valves (PSVs), participating and facilitating Process Hazard Analysis (PHAs), and providing construction & commissioning support.

Partnering with Clients

 Our process engineering group has registered professional engineers in multiple states.  We employ a collaborative approach with our clients to fully understand the project goals and constraints.  Recognizing that in many cases there are multiple “right” answers to a given problem, we supplement our clients’ operating expertise with the technical knowledge to achieve the best possible solution for the project.
