- Worth asking
An allocation well is on this lease
A well drilled across several tracts shares its production by an allocation formula, so the decimal is not always your acres over the unit acres. Ask the operator for the allocation formula and the tract factor for your land.
- Worth asking
A substandard-acreage flag is in the permit records
The RRC permit records include a substandard-acreage flag. Ask which acreage applies to your well and how it was used in your decimal.
