Learn the latest methods for calculating gas well performance from reservoir to sales. Reservoir perfomance covers the fundamentals of reservoir gas flow and details the best methods for testing wells, according to the time and money available. Reserve calculations and diagnostic testing from production data are covered. The importance of flow regime and non-darcy flow on test deisgn 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. Participants will learn to calculate and determine the effect of each system component on total well performance, which permits optimum sizing of tubing, flowlines, separators, and compressors. Problem-solving sessions, using computers, wil allow participants to evaulate field problems. Participants receive free software at the end of the coures.

Participants will learn how to:

• Apply proven techniques to field problems which increase profitability
• Calculate gas well performance, from the reservoir to the sales line
• Optimize gas well production
• Relate reservoir and well performance to time
• Predict when a well will die due to liquid loading
