The well was drilled to a total depth of 9,050ft (2,760mt). Results indicate a gas column of approximately 450ft (137mt).

George Kirkland, vice chairman of Chevron, said: “The success of Yellowglen-1, following closely on our recent Satyr-1 and Achilles-1 discoveries in the same area, highlights Chevron’s exploration capabilities in the region and helps demonstrate the significance of Australia to Chevron’s energy portfolio.”

Jim Blackwell, president of Chevron Asia Pacific Exploration and Production, said: “This discovery adds to the growth of our natural gas business in Australia. We plan a robust program of exploration, appraisal and seismic programs in Australia in 2010.”

Chevron Australia is the operator of WA-268-P with a 50% interest.
