Abstract: A system and method is provided for facilitating remote real-time surveillance, management, optimization, and control of pumping systems at a wellsite. A variety of sensors are deployed along pumping systems, such as electric submersible pumping systems, positioned in wellbores. Data from the sensors is output in real-time to a remote location via a network. The system analyzes the data to identify problems and potential problems in the pumping systems and suggest possible causes and corrective measures. The network can be used to provide two-way communication such that control signals may then be sent from the remote location to the pumping systems. Alarms may also be triggered when sensor data or data trends fall outside predetermined ranges.

Abstract: A system and method are provided for identifying underperformance in a pumping system used to produce a desired fluid. Various conditions are sensed during operation of the pumping system, and those sensed conditions are used to determine measured parameters that are provided with an associated confidence factor. The measured parameters in conjunction with the confidence factors are compared to a reference composite curve for the specific pumping system to determine whether actual performance has satisfied underperformance criteria or moved across a threshold into underperformance.

Abstract: A system and method for profiling and modifying fluid flow through a wellbore. The system comprises a logging system, a downhole unit, and a deployment system. The logging system comprises a logging tool. The downhole unit is operable to house the logging tool. In addition, the downhole unit is operable to selectively secure a retrievable fluid barrier within a wellbore casing. The deployment system is operable to deploy the downhole unit in the wellbore casing. The method comprises deploying the downhole unit into the wellbore and securing the retrievable fluid barrier below a first group of perforations. The method also comprises operating the logging tool to detect a wellbore fluid parameter.
