n: a measure of the electrical resistance of fluids in a formation. formation sensitivity n: the tendency of certain producing formations to react adversely to invading filtrates.

a measurement of the electrical resistivity of a formation. The measurement will be significantly affected by the type of fluid and the salinity of water based fluids within the pores of the rock.

the tendency of a formation to react with fluids, usually filtrates from injected fluids.

n: a method of thermal recovery in which water at the boiling point is injected into a formation to lower the viscosity of the oil and allow it to flow more freely toward producing wells. Although generally less effective than steam injection because of lower heat, hot waterflooding may be preferable under certain conditions, such as formation sensitivity to fresh water or high pressures.
