    Apache natural gas well has leak beneath floor of U.S. Gulf

    NEW YORK | Sat Feb 16, 2013 1:58pm EST

    Feb 16 (Reuters) - Natural gas from a well being drilled by Apache Corporation in the U.S. Gulf of Mexico has flowed underground, leading U.S. regulators to order the company to prepare to drill a relief well to control the flow if necessary, the U.S. Bureau of Safety and Environmental Enforcement said.

    BSEE Responds to Well Control Event

    February 14, 2013- BSEE is responding today to a report from offshore oil and gas operator Apache Corporation of an underground flow of natural gas at an exploratory well being drilled in the Gulf of Mexico approximately 50 miles east of Venice, LA. There is no detection of gas at the seafloor or pollution at the location.

    The rig was drilling in 218 feet water depth with a blowout preventer located on the rig. When the initial well control event occurred, Apache successfully activated the blowout preventer to prevent gas from flowing to the surface. The underground flow was detected through additional testing.

    Non-essential personnel have been removed from the drilling rig. BSEE is overseeing Apache's well control efforts. As a contingency, BSEE has directed Apache to make preparations to have an additional drilling rig onsite.

    More information will be released as it becomes available.

    Gulf of Mexico update

    On Feb. 5, during drilling operations at Main Pass 295 in the Gulf of Mexico utilizing the Ensco 87 rig, Apache took a kick from an abnormally pressured gas zone. The well was shut in, and the blowout preventers are functioning properly. Apache is working with well control experts from Boots and Coots to kill the well. Diagnostic procedures indicated an underground migration from the bottom of the well (8,261 feet) to another sand formation at approximately 1,100 feet. At the direction of the Bureau of Safety and Environmental Enforcement, Apache is preparing to move the Rowan Cecil Provine, another drilling rig currently under contract with Apache, to the location in the event it is determined that drilling a relief well is necessary.

    There were no injuries associated with the incident.


    We evacuated non-essential personnel from the rig, and notified the government. Safety and equipment procedures have worked as designed and tested.
    • There are no bubbles on the surface
    • Divers have verified there is no breach on the seafloor
    • This event involves natural gas; there are no associated hydrocarbon liquids involved
    • We evacuated 15 people; we currently have approximately 50 people onboard.

    Apache hires U.S. drilling specialists to kill gas well in Gulf of Mexico

    Houston, United States (4E) – In an attempt to block natural gas movements from underground formations at the site, drilling specialists on Tuesday decided to intervene by pumping heavy fluids into Gulf of Mexico’s gas well.

    The decision came nearly two weeks after workers discovered an uncontrolled flow of fluid at one of the Houston-based Apache Corp’s wells.

      Steffy: Real-life case shows how to avoid a Gulf disaster

      Posted on February 25, 2013 at 7:03 am by Loren Steffy
      ...
      Other than the kick, the Apache incident had little in common with the Deepwater Horizon accident. The Macondo well that was being drilled at the time of the blowout was in more than 5,000 feet of water. The Apache well was being drilled at a water depth of about 200 feet.

      The Deepwater Horizon’s blowout preventer, which was supposed to be the ultimate fail safe against a disaster, rested on the seafloor almost a mile below the rig. In Apache’s case, the device was on the rig itself.
      ...
      Pritchard, who’s also a member of the Deepwater Horizon Study Group, a team of researchers and industry experts assembled by the Center for Catastrophic Risk Management at the University of California at Berkeley, noted that, based on news accounts of the incident, Apache relied on the blowout preventer to avert catastrophe.

      “That is the last-resort layer of protection,” he said. “This industry has a lot to learn about layers of protection.”

        Gulf of Mexico statement

        On Feb. 28, Apache reported that well control operations at Main Pass 295 have been successfully completed. The bottom of the well has been plugged and cemented and the migration of natural gas to another sand formation (which was occurring approximately 1,100 feet beneath the seafloor) has been stopped. No injuries or negative impact to the environment were associated with this incident. Apache currently is evaluating next steps for the well.
