Abstract:
A wellhead assembly including a towable oil lift system, a drum, a wireline spooled on the drum, and a level wind mechanism is set forth to extend the wireline into and out of a well casing for production of a well. The wireline spools over a measuring wheel and extends into the well and supports a bailer on the end of the wireline. The bailer has a foot valve for filling, thereby enabling retrieval of a bailer into a surface located seal assembly connected with an air pump to force liquid from the bailer. A control system enables cyclic operation.
