Reservoir Geology Consultants Limited was set-up in 1996 as a niche consultancy, specialising in the assembly of geologically realistic 3-D reservoir models through the incorporation of detailed sedimentology and sequence stratigraphy.

There are 3 integrated facets to our work:


Huw Williams studied geology at Oxford Polytechnic and has a PhD in Upper Carboniferous fluvio-deltaic sedimentology. After 2 years of post-doctoral research at Keele and Liverpool Universities, Huw joined Shell Research in 1988. After four years in the Geocap 3-D reservoir modelling group he was transferred to Warri Nigeria from 1992-1995, and then moved to the the oil shale research group in the US before leaving Shell in 1996 to set-up RGC.

Paul Davies studied geology at Aberystwyth University before completing a PhD in Lower Palaeozoic deep water turbidites at Keele University. After a year of post-doctoral research at Bergen University, Paul joined the Geocap 3-D reservoir modelling group in 1989. After being transferred to Shell Expro (Aberdeen) in 1994, Paul left Shell in 1997 to join the consultancy.
