Unit facts

Formation: Bakken
Acres: 1,280
Type: Spacing unit
Land described: T158N R91W sections 20, 29
Pool: Kittleson Slough-Bakken
Zone: Zone VIII
County: Mountrail County
Surveyed wells inside: 1
Most wells operated by: Slawson
Unit id: dsu-09317b709fca9dead1e4
Wells allowed by the latest linked order: 7
Wells assigned to this unit: 1
Pending permits inside: 5
Balance under the allowance: +6
First linked order: Aug 30, 2011
Laterals that still fit (Nov 2026 method): 3 (2.86 two-mile equivalents)
Neighbourhood target density: 3.8 two-mile laterals per 1,280 acres
Density drilled so far: 0.91 per 1,280 acres

Room to drill: 3 laterals still fit at the density this unit's neighbourhood has reached (the larger of the 75th percentile of mature units within 10 miles and the median of units drilled in the last three years), placed in the widest gaps with the setbacks of the November 2026 method. Machine-made and geometric: not a commitment to drill, not a permit, order, lease or plan, and no economics. Land is counted once, so a unit under a larger unit shows only what the larger one left. How it is computed.
