Paper: Producing Coal Gas Wells In The San Juan Basin With The Progressing Cavity Pump

Within the last few years the progressing cavity pump has been successfully utilized as a method of deliquifying coal gas wells in the San Juan Basin. The progressing cavity pump has many advantages over other types of artificial lift. Ideally for the San Juan Basin progressing cavity pumps are capable of producing abrasive fluids at high volumes. The low profile is less obtrusive than other types of artificial lift, facilitating acceptance in the national forests. Through research, the initial problems experienced running progressing cavity pumps in the mid 1980's have been dealt with and solved therefore opening the door to an economical and effective method of producing coal gas wells in the San Juan Basin.
