    IRVING, Texas – ExxonMobil has increased its estimate of the discovered recoverable resource for the Stabroek block offshore Guyana to about 10 Bboe.

    The updated resource estimate includes a new discovery at the Cataback-1 well, the 21st significant discovery on the Stabroek block.

    The Cataback-1 well encountered 243 ft (74 m) of net pay in high quality hydrocarbon bearing sandstone reservoirs. It is located about 3.7 mi (6 km) east of Turbot-1 and was drilled in 5,928 ft (1,807 m) of water by the drillship Noble Tom Madden.

    Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil, said: “This discovery adds to the resource in the Turbot/Tripletail area, enhancing the development project potential.”

    ExxonMobil affiliate Esso Exploration and Production Guyana Ltd. is the operator and holds 45% interest in the Stabroek block. Hess Guyana Exploration Ltd. holds 30% interest and CNOOC Petroleum Guyana Ltd. holds 25% interest.

    Hess CEO John Hess said: “We continue to see multi-billion barrels of additional exploration potential remaining on the block.”
