Chevron completed the sale of GA Technologies.

The La Jolla-based company was purchased for $50 million by a group of Denver-based companies controlled by brothers Neal and Linden Blue. Chevron, which took over GA Technologies as part of its 1984 acquisition of Gulf Corp., sold the high-technology research center as part of a debt reduction program. GA Technologies, which relies heavily on federal government research contracts, reported revenue of $154.5 million in 1985. It has about 1,250 employees.
