Executive Summary
Fluor performed engineering, procurement and construction for SOHIO Construction Company's produced water treatment facilities at SOHIO's Prudhoe Bay, Alaska plant. The completed facility received produced water from existing production facilities, separated oil from the water and purified the separated oil.
Client's Challenge
On the North Slope of Alaska, water that was produced with crude oil was pumped back into the formation to help maintain pressure in the reservoir. The purified water was injected into two separate geologic formations by high-pressure turbine injection pumps. The oil was transferred to the pumping facility of the Trans-Alaskan oil pipeline.
Fluor's Solution
Modular design was used to overcome the problems of Arctic construction. Scheduling was critical, as the breakup of ice in the Arctic Circle occurs only during a six-week period in August or September.
Under our supervision, the plant was assembled and pretested in a fabrication yard then barged to Alaska. There were 27 modules and other large skids of up to 670 tons each in the shipment. After successfully negotiating the ice floes to Prudhoe Bay, the modules were offloaded and transported by motorized crawlers to the site.
Conclusion
In addition to the design, procurement and construction of the modules and skids, we performed the design, procurement and construction work for cross country pipelines at Prudhoe Bay, which conveyed the purified produced water to injection wells outside the oil gathering centers.
