What is an affidavit of non production?

In oil and gas law, an affidavit on non-production is a notarized document which asserts that no producing oil/gas well exists within a specified area. By affying that the lease is not being held by production of oil or gas from a well, an affidavit of non-production serves as termination for an oil and gas lease when the primary lease term has expired. The document may also make assertions about the nature of drilling operations and shut-in payments for that piece of land, depending on the terms of the lease.
