Surplus Acreage

Definition(s)

Surplus Acreage

Substandard acreage within a lease, pooled unit, or unitized tract that remains unassigned after the assignment of acreage to each applied for, permitted, or completed well in a field, in an amount equaling or exceeding the amount established for standard or optional drilling units.
