In recent years advances in computing and control technology have enabled real time monitoring, surveillance and control of reservoir, well and process; Within the Exploration and Production (E&P) industry these technologies are increasingly being applied throughout all phases of oil and gas field development and production

Arguably least attention has been given to asset operations, where the rewards are actually harvested. "Smart" technologies can significantly increase value here, provided they are properly focused and implemented, and integrated into the facilities daily operations.

The successful implementation of smart applications requires new ways of working and different skill sets of the operators and support engineers. This is a particular challenge in mature assets, where the operational style has become embedded through time.

Fieldware Production Universe, "PU" is an application developed within the Royal Dutch Shell Group, ("Shell"). Real time signals from individual wells e.g. tubing head pressure, are processed by numerical "data driven" models to estimate three phase flow from individual wells. Total production from the facility is reconciled to individual wells using these estimates.

These flow estimates change the traditional process of periodically routing a well's production to a test separator; individual well flow information is available all the time and tests are performed only when necessary to validate or update PU models. A more advanced version of PU, PU-RTO also allows the use of the models for real time production optimisation.

To get from research to a fully implemented and sustainably used product is a lengthy and sometimes arduous task. Across the industry most operators can think of at least one system that has been "rolled out" but not been fully adopted and has "died" before it delivered it's full value. Reasons for failure are many, but often centre around support and delivery of true benefit to end users.

This paper discusses Shell's experience with, PU, and it's application for real time production optimisation on the Nelson platform in the UK sector of the North Sea. The paper describes PU, how the applications were implemented, some of the challenges faced during the implementation and the changes that have had to be made, resulting in a PU becoming a sustainable part of the "way we do business".
