Analyzing Well Performance

James N. McCoy, Augusto L. Podio, Keneth L. Huddleston

Analyzing well performance is an important step toward increasing profits by improving production techniques. The analysis is made by field tests and examination of well data. The acoustic liquid level instrument permits determination of the producing and static bottom-hole pressures and hence the producing rate efficiency of the well. Improvements in the acoustic determination of bottom-hole pressures for practical needs have occurred in recent years and are presented herein.
