In 2015, the company generated $2 billion from monetizations. During the 4th quarter, the company closed on the previously announced divestiture of its Powder River Basin CBM gas gathering system. Anadarko achieved first oil at its Lucius development in the 1st quarter of 2015, just over three years after sanction. The 80,000-BOPD facility is Anadarko’s largest truss spar completed to date. Production reached nameplate capacity during the 2nd quarter. Anadarko grew its divesture-adjusted U.S. onshore volumes by 4% in 2015 while decreasing its operated U.S. onshore rig fleet from an average of 37 rigs in 2014 to an average of 25 rigs in 2015 and exiting the year with 16 rigs. Anadarko enhanced its Wattenberg wellbore design, which along with other efficiencies, allowed the company to reduce its Wattenberg drilling costs per foot by 50% and completion costs per well by approximately 32% in 2015 from 2014. The increased efficiencies allowed Anadarko to reduce its average rig count by almost half in Wattenberg in 2015 from 2014, while still drilling approximately 90% of the type-well equivalents. CREATING OPTION VALUE WITH EXPLORATION In 2015, Anadarko drilled a successful appraisal well at Shenandoah in the Gulf of Mexico. The well encountered more than 620 net feet of oil pay and continued to progress the giant oil discovery toward development. Offshore Colombia, Anadarko announced the play-opening discovery at Kronos, which encountered between 130 - 230 net feet of naturalgas pay and proved the presence of a working petroleum system. Anadarko achieved first oil at its Heidelberg development in the 1st quarter of 2016, less than three years from sanction. Heidelberg is the sister spar to Lucius. The 80,000-BOPD TEN development off the coast of Ghana was more than 80% complete at the end of 2015 and is on track for first oil in the 3rd quarter of 2016. The TEN FPSO departed Singapore in January 2016. Upon the FPSO’s arrival in Ghana in the 1st quarter, the vessel will begin connecting to the risers and subsea infrastructure. The company exited 2015 with an inventory of approximately 230 iDUCs, primarily in Wattenberg, Eagleford and the Delaware Basin. The iDUCs increase Anadarko’s capital flexibility for 2016.
