Abstract

The potential for improved oil recovery by surfactant flooding and by water alternating gas injection (WAG) in Norwegian North Sea sandstone reservoirs has been evaluated. 15 fields containing various formations and reservoirs have been studied, some very roughly and some in more detail. Reservoir types that seem to be suitable for surfactant flooding or for WAG have been identified. The volume of remaining oil after waterftood has been taken as a starting point in these fields to obtain a range for the potential increase in oil reserves. Other IOR-methods with a possible recovery potential are discussed briefly. Finally some attention is given to the timing of EOR projects from a national perspective.
