ExxonMobil Announces Start of Kizomba C


    Exxon Mobil Corporation (NYSE: XOM) announced today that its
    subsidiary, Esso Exploration Angola (Block 15) Limited (Esso Angola),
    has started production from the Kizomba C development, designed to
    develop 600 million barrels of oil from the Mondo, Saxi and Batuque
    fields in approximately 2,400 feet (800 meters) of water more than 90
    miles (145 kilometers) off the coast of Angola. The Kizomba C
    Development has come on stream with the Mondo field. Saxi and Batuque
    are expected to come on stream in 2008. Mondo production is
    anticipated to plateau at a peak rate of 100,000 barrels a day, and
    plateau production from the three fields (Mondo, Saxi and Batuque) is
    anticipated to reach a total of 200,000 barrels a day.

    The Kizomba C development includes two floating production,
    storage, and offloading (FPSO) vessels and 36 subsea wells making it
    the largest subsea development operated by ExxonMobil affiliates
    worldwide. This is another good example of ExxonMobil´s project
    management capabilities delivering superior results. ExxonMobil´s
    "design one, build multiple" strategy resulted in the Kizomba C Mondo
    FPSO being completed in record time of 23 months from the project
    approval to first oil.

    "The startup of Kizomba C is another important step in our work
    with Sonangol to develop Angola´s significant petroleum resources.
    Through timely and cost-efficient development of this important
    resource, we were able to provide additional volumes to meet the
    world´s ever-growing energy demand," said Mark Albers, senior vice
    president of Exxon Mobil Corporation. "This project is another example
    of our commitment to strengthen local business capability and
    integrate it with our deepwater execution experience and capabilities
    in a manner that maximizes the value of the resource for our
    shareholders and the Angolan government."

    The Kizomba C development continues Esso Angola´s tradition of
    strengthening and expanding the capabilities of Angolan companies.
    Nearly $1.5 billion has been spent on local goods and services for
    Kizomba C including contracts for in-country fabrication, logistics
    support, training, and development of Angolan personnel. Angolan
    expenditures have increased significantly over time as local
    companies, working with ExxonMobil and Esso Angola, have developed the
    capabilities to perform work required for such complex projects.
    Angolan suppliers played an instrumental role in the implementation of
    the project by providing subsea manifolds, helidecks, laydown modules,
    umbilicals, anchor piles and specialized turret components that were
    successfully fabricated in Angola. The fabrication of the high
    strength steel turret components was the first of its kind in Angola.
    These national content efforts have resulted in sustained growth of
    Angolan capacity and expertise needed to support future oil and gas
    developments.

    The Kizomba C FPSOs are the fourth and fifth offshore production
    hubs on Angola Block 15. The Kizomba C Mondo project brings the total
    of ExxonMobil worldwide startups to seven within the last 12 months.
    These significant projects such as Marimba North and Rosa in Angola;
    Waddenzee in Netherlands; Ormen Lange, Statfjord Late Life in Norway;
    and RasGas Train 5 in Qatar, are expected to deliver production rates
    in excess of 400 thousand barrels a day of oil and more than 3.5
    billion cubic feet of daily gas to world energy markets.

    With global energy demand expected to increase by approximately
    one-third by 2030 versus today, and new supplies increasingly found
    far from the world´s major consuming nations, Kizomba C and these
    other new projects are vital links in an increasingly interdependent
    global energy supply network.

    In addition to Esso Angola (operator, 40 percent), other
    participants in Block 15 are BP Exploration (Angola) Limited (26.67
    percent), ENI Angola Exploration B.V. (20 percent) and Statoil-Hydro
    Angola (13.33 percent). Sonangol is the Concessionaire.

    in this release are forward-looking statements. Actual future results,
    including production rates and sales volumes; project plans,
    schedules, and capacities; and commercial arrangements could differ
    materially due to changes in long-term oil and gas price levels or
    other market conditions affecting the oil and gas industry; political
    or regulatory developments; reservoir performance; timely completion
    of development projects; technical or operating factors; the outcome
    of commercial negotiations; and other factors discussed under the

    Information section of our website (www.exxonmobil.com). References to
    quantities of oil and gas include volumes that are not yet classified
    as proved reserves but that we believe will be produced in the future.
