What can I do if the owner of the well I lease from does not make needed repairs timely?
Answer depends on the terms of the contact. Look at what it says about the time table for repairs. Look at whether it refers to within a reasonable time, time is of the essence or something similar. Look to see if you have the right to repair and charge him if he does not repair within a reasonable time. If the problem is ongoing, you might ask for an amendment to the contract to address these issues.
