Gas Well Liquids Injection Using Beam Lift Systems

There are several concepts now available in the industry to pump water downward below a packer in a gas well and allow the gas to flow freely up the casing of a gas well. This reduces the flowing gradient and allows gas flow to occur at a lower flowing bottom hole pressure. Also it eliminates any water disposal problems. This can now be done with ESP systems, PCP systems and also beam lift systems. In order for these systems to perform, a zone below the gas producing zone must be available where the water can be injected below a packer. According to Enviro-Tech Tools, State Regulatory Commissions are classifying this method as a Class II injection well, and as such they require underground injection control permits. This paper centers on discussion of some systems using modified beam lift systems to inject water in a gas well to enhance gas production. Systems are reviewed and some field experience is discussed.
