Abstract
A system for lifting water from a gas well uses a propellant charge. The propellant charge with a plunger above is lowered into the well to a depth below the water level in the well. The propellant charge is then ignited to rapidly generate combustion gases that push the plunger upward to lift water from the well.
Claims17
A method for lifting water from a well comprising:
- placing a propellant charge in the well at a depth below the water level in the well;
- placing a plunger in the well above the propellant charge;
- and
- igniting the propellant charge to generate combustion gases, thereby pushing the plunger upward to lift water from the well.
1 more element
An apparatus for lifting water from a well comprising:
- a propellant charge;
- a plunger above the propellant charge;
- and
- an igniter to ignite the propellant charge after the apparatus has been lowered to a depth below the water level in the well, thereby generating combustion gases and pushing the plunger upward to lift water from the well.
1 more element
An apparatus for lifting water from a well comprising:
- a substantially cylindrical propellant charge;
- a plunger above the propellant charge;
- an igniter to ignite an end of the propellant charge and thereby cause the propellant charge to burn axially along its length;
- and
- a barometric firing device triggering the igniter to ignite the propellant charge after the apparatus has been lowered to a predetermined depth in the well below the water level in the well, thereby generating combustion gases and pushing the plunger upward to lift water from the well.
