10-acre Satellite Drilling Island at Endicott designed for 50 wells. Deadhorse contractor service area with more than 100 separate leases administered by State of Alaska to contractors and service companies supporting Prudhoe Bay development. More than 1,000 acres. Kuparuk Industrial Center with consolidated facilities for contractor operations supporting Kuparuk oil field development, managed by North Slope Borough. Abandoned gravel pits left after gravel mining to support oil field development Flooding of abandoned pits to provide fish overwintering habitat and fresh water for industrial use Permanent gravel roads adjacent to pipelines to support pipeline construction Temporary ice roads to support pipline contruction.
Roads melt in spring, leaving no visible trace.
Gravel pads for all onshore and some offshore exploratory drilling Ice pads for exploratory activities in which wells can be drilled in single winter season Construction of roads in close proximity to pipelines and installation of pipelines close to tundra surface Separation of roads and pipelines and elevation of pipelines to 5-foot minimums to facilitate caribou movement in the oil fields, based on more than 10 years of research Impounded water resulting from gravel road and pad placement Studies on the use of arctic pendant grass to revegetate disturbed wetlands, providing valuable habitat for water birds. Culverts to eliminate most impoundments, and geobotanical mapping to avoid sensitive, high-value habitat areas with road and pad placement. Expected to operational by mid-1990's. 5,600 acres of tundra directly affected by Prudhoe Bay development, using best available technology of the day 1,500 acres of tundra directly affected by Prudhoe Bay development if it were built from scratch today, using current technology. Reduction primarily due to eliminating duplication of facilities and reserve pits, more compact facilities and closer well spacing.
