Abstract
An artificial lift system provides an artificial lift design specifically for the pumping of liquids from natural gas wells, but not limited to this application. In doing so, production rates and reserves recovered can be significantly increased. The artificial lift system uses small diameter continuous tubing to run the pump in the hole and deliver small volumes of high pressure dry gas as a power fluid to the pump. This power fluid forces liquid that has been drawn into the pump from the bottom of the wellbore to surface. By removing the liquids from the wellbore the natural gas can flow unrestricted to surface. The design and equipment allow for a cost effective artificial lift alternative.
Claims33
An artificial lift system, comprising:
- a gas compressor;
- a gas pump seated downhole in a well;
- and
- power conduit extending along the well and providing a fluid connection between the gas pump and the gas compressor.
The artificial lift system of claim 5 in which the breakable fastenings are shear pins.
An artificial lift system comprising:
- a downhole pump;
- a power conduit connected to the gas pump;
- and
- a downhole release mechanism between the power conduit and the downhole pump.
A method of installing a downhole pump in a well, the method comprising the steps of:
- attaching a downhole pump to a power fluid conduit;
- and
- lowering the downhole pump and power fluid conduit into the well.
A method of removing an artificial lift system from a wellbore, comprising the following steps:
- disconnecting a power conduit from a downhole pump;
- pulling the power conduit from the wellbore;
- and
- pulling the downhole pump from the wellbore.
A downhole release sub comprising:
- a downhole release mechanism;
- a downhole pump connector being releasably attached to the downhole release mechanism;
- and
- a power conduit being attached at one end to the downhole release mechanism.
