Petroleum Engineering and Consulting

Stillwater offers a unique array of professional engineering and consulting services for the petroleum industry. We specialize in layout and engineering design for: retail/convenience store facilities, truck fueling facilities, fleet-fueling facilities, bulk plants, marina and airport fueling systems, emergency generator installations, aboveground storage tank systems, and numerous other petroleum system applications. Stillwater professionals have built extensive relationships with major oil companies and petroleum marketers to better understand the needs of the retail operation, and with petroleum industry suppliers such as equipment manufacturers, petroleum system contractors, and other specialized industry providers such as canopy manufacturers and signage/imaging companies to better understand the latest industry technology. Our engineers and designers have an intimate knowledge of the important and unique aspects of a fueling facility, and are experienced with the specialized regulatory environment that applies to petroleum related operations. Municipal Land Development Code routinely includes specialized criteria for fueling facilities and Stillwater is experienced in identifying these criteria. Other regulations such as State rules which address performance standards for petroleum systems (i.e. Florida Administrative Code, Chapter 62-761), NFPA, and NEC are also well understood by Stillwater professionals.
  • Customers: Stillwater strives to understand the needs of their petroleum clients and to provide a site design that incorporates their specific requirements, and optimizes use of the property given the surrounding demographics, future development, competition, and traffic flows. Considerations such as the quantity of fueling positions, tank sizes, store size, car wash offering, spacing within and around the fueling areas, and more are evaluated with each customer. Understanding the retail end of the industry is key to providing valuable input.


  • Regulations: Stillwater stays familiar with the regulatory environment surrounding the petroleum industry and regularly communicates with environmental agencies to stay on top of new rules and code which impact these projects. Because of our in-house Environmental Consulting services, we have full-service capabilities to deal with existing or new environmental conditions, and to coordinate new site development issues with ongoing environmental assessment or remediation efforts at sites.


  • Contractors: Stillwater works closely with petroleum system contractors (PSSC) to better understand issues related to the layout of the petroleum storage tanks and distribution system including the piping and dispensers. We have worked with most PSSC’s in Florida and numerous others throughout the Southeast.


  • Equipment: Stillwater works closely with petroleum equipment manufacturers and suppliers to keep up to date on the ever- changing products and equipment. We are familiar with numerous tank designs, dispenser models, piping and sump products, and monitoring systems. We keep an extensive library of petroleum equipment drawings and specifications to be used for the clients specific needs
