Intensive Trainings
Gas Well Performance & Deliquification
November 25 - November 29
Why Choose this Training Course
This gas well training course provides the skills to understand and analyze gas well performance, and to select and design those remedial measures. It addresses all four gas well components i.e. reservoir performance, inflow performance, outflow performance and surface performance, individually and combined.
Gas wells are the most uncertain and therefore critical component of any gas production system. The success of a gas project hinges on accurate forecasting of gas well production and the timely implementation of measures to restore, sustain, and enhance well capacity, thereby maximizing reserves.
In depletion-drive gas reservoirs, outflow performance of the gas well is inevitably affected as reservoir pressure declines, leading to a gas rate that is insufficient to lift water and condensate to the surface. This condition, known as liquid loading, results in a significant loss of well capacity and reserves. The gas well training teaches participants how to recognize and predict liquid loading, introduces techniques to mitigate it, and provides instruction on selecting, designing, installing, and operating a comprehensive suite of deliquification measures.
The gas well training is structured around a series of lectures and exercises. The lectures are interactive, featuring field examples to illustrate models and concepts, and encouraging participants to share their own relevant experiences. The exercises involve using Excel worksheets for model calculations, with participants invited to apply their own field-specific well data. When arranged in advance, PROSPER gas well performance software may also be used.
This gas well training also addresses methods for monitoring and managing gas well performance and deliquification, covering the purpose, outcomes, and benefits of surveillance and capacity measures to aid in future planning. It specifically focuses on the selection and implementation of deliquification measures.
Overall, this gas well training provides the skills and tools necessary for the periodic review of gas well performance, supporting critical business processes.
