Alpine Satellite Development Plan

ConocoPhillips Alaska, Inc (CPAI) proposed to develop two oil and gas accumulations in the Colville Delta east of the Petroleum Reserve and three accumulations within the Petroleum Reserve. The Environmental Impact Statement (EIS) examined CPAI's proposal and other potential oil and gas development in the area.



CPAI currently operates their Alpine Central Processing Facility (ACPF) near Nuiqsut, Alaska. CPAI has proposed to develop oil and gas from five satellites. Two proposed satellites known as CD-3 (CD North during exploration) and CD-4 (CD South) are in the Colville Delta. Three other proposed satellites known as CD-5, CD-6, and CD-7 (Alpine West, Lookout, and Spark, respectively, during exploration) are in the Petroleum Reserve. The CD-3 and CD-4 satellite locations involve lands owned, respectively, by the State of Alaska and by Kuukpik Corporation, a Native-owned corporation created by the Alaska Native Claims Settlement Act (ANCSA). The State and another ANCSA corporation, the Arctic Slope Regional Corporation (ASRC), own the oil and gas associated with these two satellites. CD-5 is proposed to be located within the Petroleum Reserve on Kuukpik land and an ASRC oil and gas lease. CD-6 and CD-7 are located on oil and gas leases in the Northeast portion of the Petroleum Reserve that are administered by the BLM.


CPAI's original proposed development of CD-3 would consist of a gravel pad capable of supporting up to 32 wells. The site would also contain a gravel airstrip that would be used for access to the site. The proposed development of CD-4 would include a gravel pad capable of supporting up to 32 wells and the construction of a 3.6-mile gravel road that would connect the site to the Alpine facility. The proposed CD-5 would require a gravel pad capable of supporting 20-30 wells and the construction of approximately 3 miles of gravel road with a vehicle-capable bridge to cross the Nigliq Channel. The proposed CD-6 development would require a gravel pad capable of supporting up to 30 wells and the construction of approximately 10 miles of all weather gravel road that would connect to CD-5. The proposed CD-7 production site development would require a gravel pad capable of supporting up to 30 wells and the construction of approximately 6 miles of gravel road that would connect CD-6 and CD-7.

Utility lines would connect each of the satellite pads to ACPF. Oil and gas products produced at these sites would be transported by a pipeline to the ACPF and after processing the finished product would be transported through an existing pipeline to the Kuparuk facility and from Kuparuk through existing pipelines to the Trans-Alaska Pipeline System.

Note that through the EIS process, CPAI modified their plans to better conform with the preferred Alternative presented in the Final EIS and the decision described in the Record of Decision.
