Feb. 2009 - Anadarko's 4th quarter Operations Report indicates that its Marco Polo facility is expected to be completely returned to production by the end of the 1st quarter 2009. The Marco Polo facility on Green Canyon 608 sustained minor damage from Hurricane Ike and was quickly repaird. Anadarko was able to maintain some oil production from the facility by re-injecting natural gas into the reservoir. However full production has been delayed due to significant damage to the third-party downstream infrastructure.

Jan. 2009 - Anadako has submitted an Initial Exploration Plan to the MMS for its Samurai prospect on Green Canyon Blocks 434 and 476. Under this exploration plan, Anadarko proposes to drill and complete eight wells, locations A, B, C and D, each taking about 90-days to drill per well. The anticipated start date is February 2009.

Sep. 2008 - Anadarko reports that the Marco Polo TLP is operational and expects production to be restored as quickly and safely as possible, and as pipelines and infrastructure permit. The Marco Polo TLP is located on Green Canyon 608 in water depths of 1311 metters and services multiple fields including Marco Polo, Genghis Khan, K2 & K2 North.

May. 2008 - Anadarko's Q1 2008 operations report says that GC561 #2 development well has been completed. The down-dip appraisal helped define the extent of the oil-bearing reservoirs present in the unit's six producing wells and has encountered new off-structure oil-bearing sands. The well is currently being sidetracked for further evaluation. Another down-dip well on GC606 #1 will commence drilling following activities on GC 561 #2.

Apr. 2008 - K2 delineation well, GC561 #2 was spud in late 4th qtr to be drilled to a measured depth of more than 30,000 feet, providing valuable data on the continuity and reservoir quality of the M-14 and M-20 sands. During 1st qtr 2008, a platform rig is scheduled to begin a two well to three well program at Marco Polo, including the completion of the GC608 A-7, which was successfully drilled in 2007.

Oct. 2007 - Hydrocarbon production began from a single well connected to a subsea manifold located on Green Canyon Block 652.
