Laterals that still fit (Nov 2026 method)
3 (1.44 two-mile equivalents)
Neighbourhood target density
4.14 two-mile laterals per 1,280 acres
Density drilled so far
0.45 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.
