This paper describes the current use of continuous live data feeds to estimate reservoir pressure automatically from build-up analysis - in real time - and to evaluate well performance from well testing automatically – also in real time.

Since 2002 much work has been done to create the Field of the Future™ Integrated Surveillance Information System (ISIS) -a universally deployable, global software application that can process continuous data feeds from remote sites, perform calculations on the data in real-time (such as virtual flow-metering of wells) and visualise the results for the user on a web browser. With these underlying calculations already complete and extending to phase rates down-hole and at surface, the current well flowing status (which wells flow through which facility components, production reconciliation, and more) there was already a mature and solid foundation on which to build a pressure analysis engine and a flow-test module.

This original pressure transient analysis (PTA) concept was to provide permeability, skin and reservoir pressure estimates using traditional build-up/fall-off techniques but with no engineer intervention required other than to approve the results. The outcome was a technology has been deployed globally and has now been in service since 2009. Using this system data is collected every time there is a shut-in event on every well for which the tool is enabled. Smart scheduling is adopted during a complete field shut-in so that all wells can be interpreted together.

The technology was built in parallel with a tool for recording production flow tests using flow-meter or separator data. Using smart systems to estimate the quality of flow tests, and combining the results with sampling and other data, a powerful system now exists to provide consistent, and fully auditable, results that can be used by reservoir modelling tools and other systems. It was deployed in 2007.

Examples are given describing use of the technology and where business has been impacted by it.
