Dynamically-configurable local operator interface for upstream oil and gas wellhead control and monitoring

Abstract

A local operator interface provides a graphical user interface to a programmable process controller (PPC) for oil and gas wellhead equipment. Configuration data reflecting the configuration of the wellhead equipment is stored by the PPC and used in controlling the operation of the wellhead equipment. A local operator interface unit retrieves the configuration data from the PPC and generates a graphical user interface on its display based on the configuration data. The operator can then selectively control operation and interact with the PPC and wellhead equipment via the graphical user interface. The local operator interface unit can be an Android-based system that also includes database management software to provide data storage and reporting capabilities.
