North Slope facility projects approved
Kristen Nelson Petroleum News
The Alaska Department of Natural Resources' Division of Oil and Gas has approved four North Slope facility projects, three by ConocoPhillips Alaska at the Colville River and Kuparuk River units and one by Hilcorp Alaska at the Milne Point unit.
On June 2 the division approved a unit plan of operations amendment by ConocoPhillips to update the portable fluid storage tank inventory at six pads in the Colville River Unit: CD1, CD2, CD3, CD4, CD5 and the Kuukpik Pad.
In its approval the division said each fluid storage tank will have a capacity of up to 600 barrels. The tanks will hold "various liquids such as diesel, gasoline, crude, drilling waste, and other substances required to support North Slope operations," and all will have secondary containment, either built-in or provided by a constructed containment area.
Tanks are temporary and will be used until contents are depleted or associated projects are completed and will then be removed from service and left in secondary containment until required elsewhere.
A unit plan of operations amendment from Hilcorp Alaska was approved June 2 authorizing extension of the existing polymer header and installation of a new polymer module at L Pad in the Milne Point unit.
The division said some 1,000 feet of 3-inch pipe would be installed to extend the polymer header to wells L-48, L-49 and L-50, with a new polymer module measuring some 8.5 by 53 feet and containing one 2,200-gallon hydration tank where polymer and water will be mixed before well injection.
The new module will be tied into the existing facility with associated piping and electrical infrastructure.
The division said the purpose of the "project is to increase polymer capacity on pad and expand injection to additional wells," with all activities from existing gravel infrastructure.
Earlier approvals On May 2 the division approved two unit plan of operations amendments from ConocoPhillips, the first for installation of a new ultra-low sulfur diesel storage facility at the Alpine Central Facility tank farm at the CD1 gravel pad, with six 750-barrel ULSD tanks to be installed with new piping and electrical infrastructure.
The new tanks will be installed on a 45-foot by 70-foot tank platform with new vertical support members, with the tanks and tank platform inside secondary containment which will be expanded by some 65 feet by 141 feet to accommodate the new infrastructure. There will be a power cable trenched some 200 feet on pad from the ULSD tanks to the existing remote electrical instrumentation module, with the trench 4 feet wide and 5 feet deep.
There will be a new heater platform 20 feet by 25 feet and VSMs will be installed adjacent to the new piping and up to six new conexes will be placed adjacent to the existing ACF tank farm, with existing storage facility and associated infrastructure to be removed prior to installation activities.
The division said the project will "support the increased activities occurring in the Western North Slope area."
Also on May 2 the division approved a unit plan of operations amendment from ConocoPhillips at the Kuparuk River unit.
The company requested authorization for installation of a new test separator module and associated infrastructure at Drill Site 1C in Kuparuk, including 11 new vertical support members to support the test separator module which will be some 14 by 58 feet.
There will be some 200 feet of on pad trenching to support tie-in activities, with all excavated materials used for pack fill or screened for contamination before being hauled to Mine Site C for reuse.
