Chevron has hired an investment bank to find a buyer for its entire position in the San Juan basin in New Mexico and Colorado in the US in what has the potential to be another high-profile exodus from the basin.

The US supermajor has retained RBC Richardson Barr to market its position comprising about 100,000 acres, spanning La Plata and Archuleta counties in Colorado and San Juan, and Rio Arriba counties in New Mexico, according to marketing documents seen by Upstream.
