Downhole Gasification for Improved Oil Recovery

IOR-C32 DOWNHOLE GASIFICATION FOR IMPROVED OIL RECOVERY AUTHOR(S) Abstract 1 M. GREAVES T. X. XIA R. R. RATHBONE AND A. H. BENTAHER Address Improved Oil Recovery Group Department of Chemical Engineering University of Bath Bath BA2 7AY England A new unique IOR concept has been investigated for application in light oil reservoirs that have been previously water flooded but which can be applied at any stage of oil production. The method operates via GSGI (gravity stabilized gas injection) but does not require the injection of displacement gas from the surface. Instead gas is generated in situ using a downhole (underground)
