Real-Time Production Flow Rate Analysis Service

Overview Library

Determine liquid flow rate and water cut at any time in the life of an ESP

The real-time production flow rate analysis service is an interpretation service for ESPs, providing high-frequency liquid flow rate and water-cut calculations. The service is available for any brand of ESP, and it is especially useful for wells requiring back allocation or reservoir pressure monitoring, or wells with intermittent production. With a dedicated team to analyze and interpret data, as well as historical logs and regular updates, this service monitors well performance for the life of the ESP.

Minimize physical testing even with high gas volume fraction

Once calibrated, the proprietary flow rate calculation algorithm is valid at any point on the pump curve. This helps to optimize testing costs by reducing the required frequency of physical testing. The liquid rate can be calculated even in the presence of phase segregation during startup and slugging, which is typically caused by high gas volume fraction.

Monitor reservoir and inflow performance in challenging conditions

In waterfloods, calculated water cut can be used to estimate incremental reserves for each well, and reservoir pressure can be monitored without buildup, even on low-mobility wells with long transients and intermittent production. Reservoir flow regimes can also be identified on wells with rapidly changing flow rate and pressure, such as unconventional wells.
