Competitive oil and gas lease · Alaska · Umiat Meridian · closed
BS is the sale area code exactly as the state files it. The state’s own lease report gives several of these codes more than one region name, so no region is named here.
Who holds this lease
Working and overriding royalty interests as filed with the Alaska Department of Natural Resources, Division of Oil and Gas. Shares add to 100% within a segment.
Segment 1 · 5,487 offshore acres · 20% state royalty
| Lessee | Working interest | Overriding royalty |
|---|---|---|
| SWEPI LIMITED PARTNERSHIP | 83.3333% | 66.66664% |
| MURPHY EXPLORATION & PRODUCTION COMPANY | 16.6667% | 13.33336% |
The state’s own royalty is shown on the segment rather than in the table, because it is the lessor’s position and not a lessee’s. Working interest sums to 100% within each segment; it does not sum across them, and a lease segregated by depth files the same acres under more than one.

The state files 5,487 acres on the case file and 0 across its sections. The case file figure is shown above; the two disagree on 1,452 of 13,139 Alaska leases and nothing in the record chooses between them. Alaska files no quarter-quarter on any of its 84,759 land rows, so a section is the finest description the record carries.
Alaska Department of Natural Resources, Division of Oil and Gas data, corpus built 2026-09-07. Case file 312850. Alaska publishes no well register — the Alaska Oil and Gas Conservation Commission holds the well and production record and does not serve it — so this page carries the leasing record and no production.
