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.
Claims25
An oil and gas well production unit for the retrieval of oil and gas from a diminishing production field, comprising:
- a well casing within said production field attached to a lubricator assembly;
- a plunger arranged for reciprocable travel within a tubing in said casing, said lubricator being arranged to assist in the production of oil and gas removal from said oil and gas well production unit;
- a plunger examination port arranged within said lubricator assembly to permit determination of the amount of wear of said plunger without having to remove said plunger from said lubricator assembly.
A method of determining the need for replacement of a oil and gas production assist plunger in an oil and gas well production unit, said oil and gas well production unit comprising a lower well casing in fluid communication with a lubricator assembly and flow outlet arrangement thereon, comprising:
- controllably moving a plunger upwardly and downwardly within said oil and gas well production unit, to facilitate the production of oil and gas output from said oil and gas well production unit;
- attaching a plunger examination port onto said lubricator assembly to permit examination of said plunger traveling thereadjacent, within said production unit.
An oil and gas well production unit for the retrieval of oil and gas from a diminishing production field, comprising:
- a well casing within said production field attached to a lubricator assembly;
- a plunger arranged for reciprocable travel within said casing, said lubricator being arranged to assist in the production of oil and gas removal from said oil and gas well production unit;
- a plunger examination port arranged within said lubricator assembly to permit condition sensing of said plunger without having to remove said plunger from said lubricator assembly.
