A lot of the cost comes from CAPEX at the front end of the life cycle of the well. There are a lot of wells out there that can produce a marginal barrel of oil for <$20. Once the companies get recapitalized or go through bankruptcy that is the new cost that will need to be looked at.
Try going into the folders and manually restoring. You can select more than one file at a time.... I was able to restore for more than 30 days... Worth a shot.
