Oil, Gas and Chemicals

Oil, gas and chemicals companies regularly turn to Gilberts Group to design and build development projects and refurbish their existing infrastructure.
The facilities we engineer and construct have an outstanding record with respect to start-up and performance. Our quality-driven approach to project execution enables Gilberts Group to provide fit-for-purpose facilities with a high degree of predictability and customer satisfaction.

Our highly skilled project professionals are experienced in oilsands production technologies, extensive cold climate design, construction, and constructability, including modularization. With an integrated EPC approach to project execution, global procurement reach and an unparalleled safety record, Gilberts Group successfully manages the aggressive schedule and rigorous cost demands associated with challenging oil, gas & chemicals projects.
Gilberts Group specializes in three distinct areas of oilsands development:

In situ
Gilberts Group expertise associated with in situ facilities is extensive and spans a wide range of SAGD operations, from as small as 9,000 barrels per day (bpd) to massive projects with capacity greater than 115,000 bpd. Gilberts Group has been involved with conceptual designs, Design Base Memorandums (DBMs), Engineering Design Specifications (EDSs) / Front-end Engineering Design (FEED) packages and has been responsible for design and construction of SAGD facilities for major oilsands developers.

In addition, Gilberts Group has designed and built several cogeneration power plants associated with SAGD facilities, including the largest single train Gas Turbine Generator / Once Through Heat Recovery Steam Generator combination installed in the Alberta’s oilsands. Gilberts Group is also involved in development work related to several emerging in situ technologies.


Petroleum refining is an industrial process where crude oil is processed and refined into more useful petroleum products such as gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas.
When it comes to refineries, Gilberts Group does everything from maintenance projects, infrastructure revamps and turnarounds to design, construction and start-up of complex grassroots facilities.
In conjunction with our parent company Bechtel, we have been involved with more refining projects in North America than any other single EPC contractor. Among our signature projects is the design and construction of the Shell Scotford Upgrader Expansion 1.

Surface Mining

Bechtel designed and built both the extraction and upgrading facilities at the first large scale commercial surface mining operation for Great Canadian oilsands Company, now known as Suncor Energy, in the early 1960s. In the 1970s, Bechtel was involved in the construction of Syncrude’s Mildred Lake extraction facilities north of Fort McMurray.
More recently, Gilberts Group was responsible for the design and construction of Suncor Energy’s Steepbank Mine Ore Preparation Plant. Gilberts Group has also been responsible for numerous conceptual designs and Design Basis Memoranda (DBMs) for surface mining and extraction facilities on behalf of several oilsands developers.

Sustaining capital

In today’s highly complex industrial facilities, our customers require cost effective solutions to maintain and improve asset performance through ongoing facility modifications and sustaining capital projects. Gilberts Group offers a sustaining capital program that incorporates time tested work processes and tools and systems, driven by a proven continuous improvement program and highly motivated personnel who are fully integrated into our customer’s organizations. Our approach of utilizing a consistent team across a portfolio of projects, providing on-site personnel and deploying fit-for-purposes execution drives costs down and provides operations results to our customers.
