When other artificial lift systems fail, especially Electric Submersible Pumps (ESPs), the result is immediately obvious and often catastrophic. However, a gas-lift system that is operating incorrectly may not be noticed for weeks or even months. A lower field and possibly well production rate will be noted, but could be attributed to reservoir inflow damage, a change in water cut, or simply a production allocation or well test measurement error. In reality, a production advantage is being lost that can rapidly account for tens of thousands of barrels of oil. An intelligent surface control and optimization system, incorporating the use of Sercel-GRC’s line of downhole gauges and surface data acquisition equipment, can be used to provide an instant warning of a change in operating behavior in a well, which will allow quick operator action and resolution of optimum production rates. In addition, a normally operating gas-lift system can be continuously optimized by proper allocation of injected gas in order to react to events such as change in gas-lift supply volume, change in manifold pressure, or water cuts.

Monitoring downhole pressure data can be used to increase pump speed to keep reservoir pressure down to allow for optimal production. Installing a downhole gauge gives the ability to monitor reservoir fluid level and prevent damage to the downhole equipment caused from dry pumping. Gauge parameters can be used to monitor pump efficiency and to act as an early warning system to prevent premature equipment failure.

Increase production by maintaining the lowest possible uid level over pump. Avoid premature pump-off due to inaccurate algorithms Improve control over motor speed by monitoring real time bottom hole data. Enable automated decision making using measurements, not assumptions or calculations. Verify pump con guration’s actual performance and efficiency Reduce lifting cost and extend life of pump.
