Horizon Secondary Upgrader - Hydrotreater Phase 2 Project

Location: Fort McMurray, Alberta

Key Players: Canadian Natural Resources

In September 2011, Saipem Canada Inc. entered into an agreement with Canadian Natural Resources Ltd. (Canadian Natural) for the engineering, procurement and construction of a Secondary Upgrader with a production capacity of 42,599 BPSD (barrels per stream day) of Hydrotreated Gas Oil as part of the Horizon Oil Sands Project - Hydrotreater Phase 2 - in the Athabasca region of Alberta, Canada.

The scope of the project includes several units to be built within the existing complex: Gas Oil Hydrotreating Unit (GOHTU), Common facilities (Substation & Rib), Wash Water and Rich Amine System, and the Interconnecting Piperack.

The complete Horizon Oil Sands Project will develop oil sands resources on the Canadian Natural Oil Sands Lease, located approximately 70 kilometers north of Fort McMurray in a phased development. At full capacity, the project will produce 250,000 B/cd of synthetic crude oil, from 270,000 B/cd of mined bitumen.

The EDS (Engineering and Design Specification) package for the Plant is entirely prepared by assembling documentation from the current design of the Plant constructed by Saipem Canada in 2008 for the same client.
