2 Reviews
No other book on the market offers such a turnkey solution to the problem of liquid interference in gas wells. Gas Well Deliquification contains not only descriptions of the various methods of de-watering gas wells, but also compares the various methods with a view toward explaining the suitability of each under particular circumstances. The material is presented as practical information that can be immediately applied, rather than a theoretical treatment. And, includes useful historical methods, but focuses on the latest techniques for de-watering gas wells.

Page 24 - The tubing pressure continues to rise. The casing pressure, which is directly related to the amount of gas stored in the annulus, also increases in response to gas and liquid entering the well. When the casing pressure reaches the predetermined maximum...
Page 24 - The tubing pressure then rises as annulus gas starts to break around the foot of the tubing. 4. When the casing pressure reaches the predetermined minimum, the motor valve closes the tubing outlet (or pinches it back), but flow into the well from the reservoir continues with very little decrease in rate.
Page 23 - Figure 2-8. 1. At the start of the flowing period, the tubing is opened by the rising casing pressure, which actuates the motor valve. The column of gas...
