    Projects and Operations // April 12, 2002
    Unocal Corporation says Unocal Rapak Ltd has successfully tested an appraisal well in the deepwater Ranggas oil field offshore Indonesia.

    The Ranggas-4 appraisal well flowed at a daily rate of 8,158 barrels of oil and 6.4 million cubic feet of gas from a single interval between 10,174 feet (3,101 meters) and 10,224 feet (3,116 meters) true vertical depth subsea (TVD). The drill stem test had flowing tubing pressure of 1,223 pounds per square inch on a 56/64-inch choke.

    The test rates were constrained by test equipment, but initial daily production rates from a well producing from this single zone are estimated at upwards of 10,000 barrels of oil and 8 million cubic feet of gas.
