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.
