Abstract
An oil and gas well production unit for the retrieval of oil and gas from a diminishing oil and gas production field. The unit comprises a well casing within the field attached to a lubricator assembly. A plunger is arranged for reciprocable travel within a tubing in the casing and the lubricator to assist in the production of oil and gas removal from the oil and gas well production unit. A plunger examination port is arranged within the lubricator assembly to permit determination of the amount of wear of the plunger without having to remove the plunger from the lubricator assembly.
