Lomax noted that a commercial project of the technology would cover about 500 acres compared with the 65 acres at Coalinga, and that Chevron could expand the site at Coalinga to a full 360° of heliostats around the tower.Ĭhevron built the central tower at Coalinga on the same scale as a commercial installation, but a higher tower height would allow for the installation of a higher density of heliostats, providing more steam per acre, Lomax said. Chevron expects to require eight full-time employees at the site. Lomax noted that problems at Coalinga include dust, wind, and hail that may add costs and hamper reliability. The demonstration project may have a 20-year life, although Lomax said Chevron should have good data within a year as to operating costs and reliability. Assessing the technologyĬhevron will monitor and gather data to determine if the technology is economically viable and practical for other Chevron locations. Lomax added that the system uses very little fresh water because of the closed process loop in the tower that recycles the process water, and Chevron injects into the wells steam generated from produced water. Enough acres of land with a flat topography.

The produced steam is about the same amount as output by a gas-fired steam generator that is the size of a large semitrailer truck compared with the demonstration project's 65 acres.Ĭhevron based its selection of the site on the availability of: It is designed to produce 690,000 bbl/year of steam or 240 million lb/year of steam. He said the generated steam from the demonstration project will supplement gas-powered steam generators at Coalinga to provide about 5% of the steam needed to produce the 8,700 b/d of 9-14° gravity heavy oil from the field.Īs currently configured, the installation produces 60% quality steam at 500° F. Jerry Lomax, vice-president emerging energy for Chevron, told OGJ one reason Chevron choose this system is its flexibility as to steam temperature, pressure, and quality. Besides EOR, BrightSource also has projects for the technology in which the steam turns a turbine for power generation. built and helped engineer the Coalinga solar-to-steam installation.
