Apparatus and methods for producing fluids from a well and for controlling
the production of fluids from multiple wells, particularly from a remote
location. The well is provided with a winch/cable drum having a cable
wound thereon with a swabbing tool on the end of the cable. The swabbing
tool is initially located in a riser that is mounted to the wellhead and
lowered into the well and down through the fluids in the well under
control of a programmable logic controller (PLC 95). Upon reaching a
pre-determined depth, the PLC 95 stops the rotation of the winch/cable
drum and then reverses the direction of rotation to retrieve the swabbing
tool, thereby lifting the fluids in the well bore up out of the well.
Flowline connections, with appropriate valves, are provided in the riser
for routing any gas and oil that is lifted from the well into pipelines
and on to storage tanks or separators as the swabbing tool is retrieved.
The PLC 95 is programmed for manual operation, for independent control of
the wellhead apparatus, and/or for operation from a remote location.
