I own a chunk of property in Venango County that has a shallow gas well located on it.  I know that at least the shallow gas is leased and since it was an old lease, I'm sure there's no depth restriction.  I am almost positive that the well is non-producing and we have never received royalties from the well.  I am pretty sure that we can get out of the lease on that fact alone, but knowing my luck I won't.  I was wondering if anyone has heard of or knows anyone who has been able to fight for their deep gas rights even with an old gas lease that doesn't have a depth clause.  Thanks.
