Jet-pump gas lift for high-water gas-well remediation
This case is summarized from public reporting and reframed as an ASBR-style completion workflow: diagnosis, tool-process matching, parameter review, field execution, and recovery review.
Challenge
As development progressed, bottom-water influence increased liquid loading and constrained gas flow. The project needed a low-disturbance path to recover production while managing water production risk.
Process design
The jet-pump gas-lift process combines injected high-pressure gas with a downhole jet pump. It improves liquid carrying capacity and uses suction-pressure control to manage bottomhole pressure, helping coordinate pressure control, water control, and liquid unloading.
Engineering review
The team compared multiple recovery options, used transient simulation and flow-test feedback, and reviewed sealing, temperature, pressure, and verification steps before selecting a phased pressure-control production strategy.
Field value
The case shows that completion stimulation is an integrated service path, not a single-tool delivery: well-condition diagnosis, tool selection, pressure management, unloading strategy, and production review must work together.
