Solving Liquid Loading Problems in Gas & Gas Condensate and High GOR Wells

About the Course

The course provides you with a basic understanding of gas well liquid unloading, including the use of standard artificial lift technology to assist in unloading and in alternative foaming agent methods. You use practical examples to enhance your understanding of the gas well liquid unloading processes.

Liquid loading in low production gas wells is a nuisance for production engineers and the most controlling factor in the abandonment of mature pressure-depletion gas and gas-condensate reservoirs. The course provides a comprehensive approach for recognizing and modeling liquid loading (load-up) process, when it will occur and which method and technology should be used to assure a well production without liquid load up at the bottom and/or in wellbore. It is essential to maintain gas wells free of liquid, otherwise, the production will be severely reduced by backpressure of the accumulated liquids, and by reduced relative permeability of the gas in the near-wellbore zone and during the course these pheromones will be supported by numerous cases. The proper selection of the tubing diameter is the crucial for providing flow conditions without liquid loading.

The proper selection means to select tubing diameter such that natural energy in the reservoir will give a gas velocity sufficient to lift liquids from the sand face and reservoir through the wellbore to the surface. Depending of dynamic conditions in the reservoir, well and surface the optimum tubing diameter varies through the well production life.
