The Long Lake commercial SAGD project facilities include a steam SAGD production field, central production facility and two cogeneration plants, which will be operated by Nexen, integrated with an OPTI‑operated upgrading facility designed to significantly reduce reliance on natural gas.
ColtWorleyParsons Calgary provided the key project management, engineering, procurement, project control and information technology functions for the SAGD portion of the project. These functions were critical to the success of the facility design and project execution. The engineering and design for the cogeneration plant was executed in the ColtWorleyParsons Edmonton office.
The Long Lake facility, the largest SAGD project in operation in Alberta, drew on our specialist resources to utilize synthetic fuel gas, produced from an upgrading process as the main fuel for the SAGD operation, which reduced the SAGD operating costs. Our specialists also provided input to the diluent‑based treating, which greatly reduced the salt content of the oil and made the front‑end desalting in the upgrader more effective. The plant also recovered all of the produced water and wastewater streams to provide high quality treated water to the upgrader.
ColtWorleyParsons was subsequently awarded the Long Lake South Phase 2 project.
