ConocoPhillips Sets New North American Drilling Record

ANCHORAGE, Alaska – ConocoPhillips Alaska Inc. announced today that it recently achieved a North American drilling record, as well as two State of Alaska drilling records, at drill site CD5 in the Colville River Unit (Alpine) on Alaska’s North Slope. CD5 is the first commercial oil development on Alaska Native lands within the boundaries of the National Petroleum Reserve-Alaska (NPR-A).

CD5-25 set the North American land-based well drilling record for longest horizontal lateral with Doyon Rig 19. CD5-25 is a dual-lateral well. The well was drilled to a true vertical depth of approximately 7,900 feet, and the record-setting lateral was drilled in the Alpine A sand. State of Alaska records set by CD5-25 were for total combined lateral length, and total combined footage for a well.

  • North American record:
    • longest horizontal lateral at 21,748 feet (Alpine A sand)
  • State of Alaska records
    • total combined lateral length (Alpine A sand lateral and Alpine C sand lateral) at 34,211
      feet
    • total combined footage for a well at 42,993 feet

“Improved technology like extended reach drilling and multilateral wells allow ConocoPhillips to maximize production while minimizing our environmental footprint,” said Shon Robinson, manager of drilling and wells for ConocoPhillips Alaska. “CD5-25 will produce from over 4 miles of reservoir in the long lateral and from over 6 miles of reservoir when both laterals are included. Innovation and teamwork were a huge part of safely drilling this well.”

CD5 is exceeding its original production target of 16,000 barrels of oil per day (BOPD) gross, and year to date, has averaged 37,000 BOPD gross. The significant increase in production at CD5 is due in part to wells like CD5-25.

The Doyon 19 drilling rig moved to the Greater Moose’s Tooth 1 (GMT1) drill site in the NPR-A in mid-March to begin drilling that project’s first well. Production from GMT1 is expected to come online in late 2018 with approximately 30,000 barrels of oil per day gross at peak production.
