The invention relates to a slim hole production system for pumping liquids to the surface of a hydrocarbon well and especially a hydrocarbon well that is producing both natural gas and liquid liquids where the diameter of the hole in the production area is too small to get production tubing and a sucker rod into a productive arrangement. The slim hole pump includes a hollow tube that raises and lowers the plunger and carries the liquids to the surface and uses the annulus to produce the gas. |
