An Environmental Scanning Electron Microscope (ESEM) has been used to investigate the freshwater sensitivity of secondary correnslte (regularly interstratlfied chlonte/smectlte) and chlorite-rich chlorlte/smectlte in order to determine whether hydrocarbon reservoirs hosting these clays should be regarded as freshwater sensitive ESEM experiments involved an examination and close comparison of selected clay areas in three samples at h~gh magmficatlon before, during and after prolonged freshwater treatments Correnslte and chlorlte/smectlte in the samples did not visibly swell when immersed in fresh water. After soaking ]n fresh water for up to three months, these clays retained their original morphology and associated porosity_ Hence, the presence of correns~te or chlonte/smectlte in a hydrocarbon reservoir need not indicate that the reservoir is freshwater sensitive
