Stephen Cannon
Stephen has worked as a reservoir geologist and petrophysicist for most of the last 35 years, having spent the preceding 5 years in core analysis and wellsite operations. He is a geologist by profession, a petrophysicist by inclination and a reservoir modeller by design!
His main interests are in sedimentology and stratigraphy and their application to reservoir evaluation and characterization. He is particularly interested in the integration of qualitative and quantitative, core and log data, and developing different strategies for rock typing and property modelling. What he really likes to do is to build fit-for-purpose static models of clastic and carbonate reservoirs: This is achieved by working closely with all the other disciplines involved in the process from the geophysicist to the reservoir engineer. Seismic to simulation workflows only function when there is a multi-skilled geoscientist in the middle who understands the reservoir framework and architecture, and how the petrophysical properties are distributed.
Stephen has been working on assets in West Africa and the Mediterranean and teaching reservoir modelling and petrophysics courses. He is also completing a book for Wiley-Blackwell on reservoir modelling, due for publication in 2018.
Stephen has worked on projects from West and North Africa, Argentina, Venezuela, Eastern Europe, Middle East, Malaysia, FSU and Siberia. Reservoirs studied have included aeolian, fluvial, deltaic, shallow marine and deep-water clastic environments, as well as reefal, platform and fractured carbonates. The projects have commonly involved integration of different subsurface datasets, (seismic, core, log and well test) to provide a consistent description of the reservoir for static and dynamic modelling. Most of the projects have included a period of on-site data gathering and reconnaissance.
In the North Sea he has undertaken field and regional studies West of Britain, including the Irish Sea, in the Brent Province, the Central and Southern North Sea and most recently the West of Shetlands, where he has been involved in building fine-scale geological models for simulation studies using PETREL 2011. While at the DTI, he worked in the SNS petroleum engineering team reviewing all field development plans prior to sanction, producing fields' annual reports and remaining reserves estimates. At DONG Energy he was TCM representative and team lead for non-operated Paleocene gas developments/discoveries including Laggan-Tormore, Tobermory and Torridon. Stephen has also been the senior internal advisor on subsurface peer reviews and asset acquisition projects.
Stephen has been fortunate to have the opportunity to publish the results of some of the projects he has worked on as well as to also edit a Geological Society Publication (SP397). In 2013 he was invited to write a book on petrophysics for Wiley-Blackwell; the book “Petrophysics: a practical guide” was published in October 2015. In 2012 Stephen was awarded an honorary membership of the Petroleum Exploration Society of Great Britain, something of which he is very proud.
