The ringed dot is this lease's well, where the Railroad Commission's map puts it. The other dots are wells and drilling permits of the last 24 months on the land around it; the counts are for everything in the picture, which is about 6 miles across. The thin brown lines are the original land surveys; where there is room, a survey carries its abstract number, the number deeds and division orders cite.

- 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 Rule 37 case is listed
The RRC permit records list a Rule 37 case. This does not establish your royalty share. Ask for the permit and unit plat for your well.
