Dewatering Systems and Techniques for Coalbed Methane Wells. Volume 2

摘要

The study shows that contemporary oil field systems are adequate for coalbed dewatering. In general, sucker rod systems were preferred for the shallower depths with fluid-operated systems more applicable for the deeper wells. No system was an overwhelming choice based on cost. Oil field electric submersibles were generally oversized for the flow rates and reservoirs used in this study.
