Production Operations

Gas Production Engineering


The rapidly increasing worldwide demand for natural gas as an energy source requires expertise in gas engineering technology. Incorporating a balance between theory and application, course emphasis is on training participants for immediate application of acquired techniques to field problems.

Learn the latest methods for calculating gas well performance from reservoir to sales. Reservoir performance covers the fundamentals of reservoir gas flow and details the best methods for testing wells, according to the time and money available. The importance of flow regime and non-Darcy flow on test design and interpretation is emphasized for new wells and for the possibility of improving the performance of older wells. Also discussed are performances of tight formations, horizontal wells, fractured wells, and methods for estimating gas reserves. Calculate and determine the effect of each system component on total well performance, which permits optimum sizing of tubing, flowlines, separators, and compressors.

Formation damage, gas well dewatering, hydrate formation, water influx, and abnormal reservoir pressure problems are reviewed. Relate reservoir and well performance to time, as well as calculate cash flow and compression requirements. Discuss the best procedures to predict when liquid loading will make a well nonproductive. Field gas processing, including dehydration and condensate recovery, is briefly reviewed. Gas production is emphasized, although an overview of field gas processing is presented

  • Apply proven techniques to field problems which increase profitability
