• Publication of major report on CO2-EOR projects worldwide and opportunities for CO2-EOR in the North Sea for Scottish Enterprise

KEY OUTPUTS 2012/13 RESERVOIR GEOCHEMISTRY

HIGHLIGHTS • Evidence of reservoir geochemical reactions from 55,000 lines of 5-12 ion

produced water data supplied by operating companies from 21 fields worldwide • Network modelling of pore scale blocking during scale deposition • Industry funded evaluation of geochemical reactions in a HP/HT/HS field in GoM • Industry funded project to use Pore Network Modelling of low salinity waterflooding to interpret

coreflood data and inform reservoir simulation calculations • Modelling impact of CO2-WAG on geochemical reactions around injectors, mid field and producers • Visit to UFPE Recife to establish joint BG Group funded PhD studentships for Brazilian nationals,

including topic Reactive Transport Simulation for Oilfield Scaling in Carbonate Reservoirs with Leonardo Guimarães
