1 (Contd.) Marginal & Stripper Wells Re-vitalization programme (USA) Few ready-to-use new technologies thru SWC.

Gas operated automatic lift pump.

An automatic plunger lift tool to remove fluids from stripper wells.

Operates automatically using on-tool pressure activated valve.

Needs no external energy.

Low maintenance and service requirement.

Vortex flow tools.

Creates vortex flow regime to accelerate velocity of water and reduces pipe friction.

Prevents water build-up in low spots of gas gathering and well flow pipelines, reducing back pressure on well head.

Another vortex tool installed at tubing bottom, reduces pressure drop up the tubing string, cutting down gas needed for lifting.

Hydraulic Diaphragm Electric Submersible pump.

Versatile pump for installation below perforations in sandy wells.

Can handle fines, gas/liquid mixtures, variable oil viscosity.

Highly efficient with reduced electrical power requirement.

Weather bee pump with/without Vacuum & Compressor.

Variable capacity compressor/pump for low productivity gas wells.

Lower initial and operating costs.

Can handle high BTU gas/water.
