HOUSTON – Mechanical issues with the production riser for the Caesar/Tonga deepwater Gulf of Mexico project will delay first production, says Anadarko Petroleum Corp. A problem was found during hydro-testing of the riser system.
“We are delaying first production at the Caesar/Tonga project after our recent hydro-test of the production riser system indicated it was not fit for service,” said Chuck Meloy, Anadarko SVP, Worldwide Operations. “The project was otherwise on schedule, as we had recently secured the necessary permits to begin completions on the first two wells; nonetheless, in the interest of safety and the environment, delaying startup is clearly the right decision. We plan to continue the completion activities as we work with the co-owners to secure a reliable alternative for the production riser.
Anadarko operates the Caesar/Tonga development with a 33.75% working interest. Co-owners include Statoil Gulf of Mexico LLC (23.55%), Shell Offshore Inc. (22.45%), and Chevron U.S.A. Inc. (20.25%). Caesar/Tonga is located in the Green Canyon area of the GoM near Anadarko’s Constitution spar in Green Canyon block 680.
