ExxonMobil is developing and implementing new systems and work processes that will increase the efficiency and effectiveness of well, reservoir, and facilities surveillance across their operated assets worldwide.  For opportunities with a significant information technology component, often referred to as "digital oilfield" initiatives, ExxonMobil applies a broadly consistent, systematic approach to the identification of technologies or suites of related technologies which will add quantifiable value given our asset mix and organizational structure.  To derive the greatest impact and efficiency, the new technologies are then implemented within established standard computing systems which allow scalable global solutions.

Improved surveillance, whether it applies to well productivity, well integrity, reservoir performance, or surface facilities, has been identified as an area with a significant opportunity for volumes uplift and for improved work efficiency.  ExxonMobil is developing a number of new surveillance tools, processes, and systems, some of which will utilize proprietary in-house technology with others developed jointly with vendors.  This paper will focus on one such initiative, termed "Production Surveillance and Optimization" (PS&O).  The PS&O initiative is a combination of enhanced IT capabilities and ExxonMobil-standard surveillance processes and best practices that will be employed worldwide starting in 2008.  Key features of the PS&O tool are that it connects to disparate datastores such as corporate data repositories and data historians, allows automated alerting when production conditions deviate versus expectations, allows automation of follow-up diagnosis and analysis, and provides access to proprietary best practices relevant to the task at hand.
