Dewatering Unconventional Gas Resources With Sucker-Rod-Pumping Equipment

Dewatering coalbed-methane and low-pressure gas wells is a challenge. Compared to electrical-submersible and progressing-cavity pumps, sucker-rod pumps are very forgiving, and wells can be pumped at very low pump-intake pressure without damaging the pumping equipment. New designs in sucker-rod-pumping equipment and rod-pumping systems for high gas/liquid ratios (GLRs), coal fines, and solids have changed the approach to dewatering unconventional gas resources.
