Embodiment Construction

[0024] In the following description, numerous details are set forth to provide an understanding of the present invention. However, it will be understood by those of ordinary skill in the art that the present invention may be practiced without these details and that numerous variations or modifications from the described embodiments may be possible.

[0025] The present invention generally relates to a system and method for remote real-time surveillance, control, and optimization of wellbore pumping systems, e.g. electric submersible pumping systems, at a wellsite. The technique enables a well operator or well field manager to better manage and optimize operation a plurality of pumping systems without physically attending the wellsite. For example, the system and methodology enhances the monitoring, surveillance, diagnostics, and optimization of electric submersible pumps using real-time and on-time data in a cost efficient manner.

[0026] Referring generally to FIG. 1, one embodiment o...

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.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention generally relates to well systems, and in particular to the management and optimization of well systems that use pumps, such as electric submersible pump (ESP) systems or pumping systems located at the earth's surface, for pumping hydrocarbon-based fluids. [0003] 2. Description of Related Art [0004] In many artificially lifted wells, pumping systems are used to produce a desired fluid, e.g. petroleum, to a collection point. For example, a wellbore may be drilled into a subterranean reservoir, and the pumping system is used to lift fluid from the reservoir location to the collection point. Pumps are used to intake fluid from the wellbore and to pump the fluid upwardly or laterally through the wellbore via, for example, production tubing. Instrumentation can be deployed in the wellbore to monitor operation of the pumping system, which may be submersible or surface-mounted. [0005] Although wellbor...
