Low salinity waterflooding is an emerging enhanced oil recovery (EOR) technique that has
attracted the attention of the oil industry. However, the classical application of waterflooding
in unconventional shale reservoirs is impractical because of the nanoscale dimension of the
matrix pores. Salinity contrast across shale matrix blocks leads to osmotic pressures which
expels oil from tight shale. This thesis exploited this phenomenon to measure osmotic
pressure in shale core plugs.
