Performance By The Numbers

Gas Lift System

Recovers Dead Well, Improves Fluid Rate, Avoids Shutting-In Gas Injector, Saves Downtime, Associated Costs

Objectives

  • Maximize production by recovering fluid from deeper, dead, and loaded-production layers with the existing low pressure in a gas-supply line to reach a deep gas-injection point.

Our Approach

  • Weatherford used data provided by the operator and Weatherford’s gas lift-design software to design and model an optimal solution.
  • Personnel deployed C-1 injection pressure operated (IPO) gas lift and CV-1 check valves on 2.8 CM-1 tubing-retrievable conventional mandrels with 2 7/8-in. tubing.
  • A Weatherford 5 1/2-in. Arrowset I-X mechanical-retrievable production packer was set at the desired depth to isolate the casing-tubing annular from formation fluid. The 2.875-in. WXA sliding sleeve was located one joint above the packer.
  • Weatherford’s gas lift system increased the fluid-production rate from 76 to 189 B/D (12 to 30 m3/d).

Value to Customer

  • Using Weatherford’s gas lift system enabled the operator to increase the fluid-production rate and return dead, potentially lower zones back to production.
  • The efficiency of Weatherford’s gas lift unloading procedure in the well saved the operator downtime and costs associated with performing unnecessary jobs using a pump truck, compressor, and swabbing unit.
  • The operator avoided having to shut-in the gas supply line of the offset wells to increase injection pressure.
  • The system enabled the adjustment of injection rates to the optimum injection-gas level and avoid extra gas consumption.
