ConocoPhillips Alaska has set North American and Alaska drilling records at the CD5 drill site in the Colville River unit. The company said earlier today that its CD5-25 well set the North American land-based well drilling record for the longest horizontal lateral, 21,748 feet. The well was drilled by Doyon Rig 19.
The well has a true vertical depth of some 7,900 feet and the record-setting lateral was drilled in the Alpine A sand.
The company also set two state of Alaska records at the well: for total combined lateral length and total combined footage for a well. The combined length of the two laterals, in the Alpine A sand and Alpine C sand, was 34,211 feet. The total combined footage for the well was a state record at 42,993 feet, the company said.
