HOUSTON, Apr. 13
-- Plains Exploration & Production Co. signed a design-build-operate agreement with Veolia Water for a 45,000 b/d produced water reclamation facility at its Arroyo Grande oil field in San Luis Obispo County, Calif.

The 12-year performance agreement with Veolia calls for performance guarantees on a fixed-fee basis to ensure design performance and high-quality recycled water.

The facility will incorporate Veolia Water’s OPUS II technology and includes ceramic membranes as pretreatment prior to ion exchange and reverse osmosis.

The treated water will be used to provide 25,000 b/d for once-through steam generation make-up and 20,000 b/d for surface water discharge, dewatering the Arroyo Grande reservoir.

Veolia Water said that the treatment process produces treated water that meets or exceeds state and federal permit requirements, and the dewatering of the reservoir will reduce the formation pressure to enable increased oil production at the site.

Prior to the agreement, Veolia Water demonstrated the technology on site for 4 months.
