Every figure here comes from a report a licensed driller filed on the day the work ended — sometimes decades ago. It describes what was found then, not what a well yields today, and it is not a statement that any well is sound, potable or still in use.
Drilling a well near grid 30-55?

We are nobody's agent and have no arrangement with any firm today. What we do with this.
