The candidate waters available for secondary recovery of oil in West Kuwait oil fields are all high in
salt. Total dissolved solids (TDS) of an aquifer water is 239,000 ppm (chloride, 146,000 ppm). Effluent
water varies, but TDS can reach 241,000 ppm (chloride, 151,000 ppm). Candidate materials for tubulars
for secondary injection were tested for MIC attack at high salt concentrations. N-80 and L-80 steels, and
three FRPs - phenolic, vinyl ester and epoxy resin were tested in the two water types. A mixed bacterial
consortium (including SRB) from a natural Mediterranean marine environment was habituated to high
salinity and used as the inoculum.
