In the March edition of JPT, a series of articles looked at professional pride. Reading them made me reflect on my own career and consider what have been my best moments in the industry (to date!). Back in the 1990s, I was part of an EOR group providing technical advice to the UK Department of Energy in support of their review and approval of field-development plans for the UK sector of the North Sea. The Captain field was under consideration for development. The viscous oil made it a challenging development, requiring waterflooding with horizontal injectors and producers and lifting with electrical submersible pumps.
I led an assessment of EOR for the UK Department of Energy showing that there were potentially viable polymer-injection strategies that could give substantial additional economic recovery. The Department of Energy approved the basic waterflood development but, on the basis of my team’s work, required some minimum preinvestment in facilities to enable subsequent polymer injection, including a polymer line in the bundle from the floating production storage and offloading vessel to the wellhead platform.
These facilities now have been used in very successful polymer-injection pilots, with the first results published last year. An excellent response is reported, showing that polymer can recover more oil more quickly than waterflooding. The current operator notes that the foresight of including the front-end provisions enabled the timely implementation of polymer flooding.
This is one of my best moments: to have made the technical case for polymer flooding and to see the fruits of this several decades later. As is so often the case in our industry, my contribution stands alongside those of many others in the intervening years who have made the EOR journey for the Captain field possible and now a reality.

Capacitance-Resistance Model Used for Integrated Detection of Water Production
The objective of this study is to show how the capacitance-resistance model (CRM) was used on this field and how it validated the use of other independent methods. This paper demonstrates that integration of different sources of data in reservoir management is critical.
The bulk of the literature on enhanced oil recovery from the past year has been devoted to an improved understanding of trends started more than a decade ago with physical and numerical modeling.
Study Investigates Smart Waterflooding in Sandstone Reservoirs
In this paper, the authors consider the effect of water chemistry on water/rock interactions during seawater and smart waterflooding of reservoir sandstone cores containing heavy oil.
