The Use of Coiled Tubing as a Velocity String
Liquid loading is a problem in many gas wells especially older and depleted type reservoirs. If steps are not taken to minimize this effect, it will severely limit the production or even "kill" the well. This is the result of insufficient transport energy in the gas phase to carry the liquid that will accumulate around the well bore. This accumulation exerts a backpressure that restricts reservoir inflow performance.Reducing the flow area of a gas well's existing production string increases flow velocity and improves the ability to unload liquids. The most economical method is to install coiled tubing inside the existing tubing string that can be done without killing the well.
