CD5, part of the Alpine Field, is the first commercial oil development on Alaska Native lands within the boundaries of the National Petroleum Reserve-Alaska (NPRA).

Initial development plans call for 15 wells by early 2017. On April 21, 2016, ConocoPhillips Alaska announced funding approval for additional wells and associated on-pad infrastructure to increase production at the CD5 drill site. The additional wells and infrastructure bring CD5 to its full design and permit capacity. 

CD5 is exceeding its original production target of 16,000 BOPD gross, and is currently producing approximately 37,000 BOPD gross average, year to date.

In addition to the production drill site and on-site facilities, the project includes a 6 mile road, four bridges, 32 miles of pipelines, and miles of communications and electrical infrastructure that tie CD5 back to the main Alpine facilities. Oil from CD5 is sent back to Alpine CD1 for processing before it is sent through Kuparuk to the Trans-Alaska pipeline. CD5 represents a total project investment of more than $1 billion (gross).

CD5 is situated within the boundaries of the NPR-A on land owned by Kuukpik Corporation, the village corporation for Nuiqsut, with mineral rights owned largely by Arctic Slope Regional Corporation.
