Saturation Height works (SWH, Swht) are a way of assigning a saturation to a volume of stone e.g. a geocell that isn't penetrated by a well by virtue of the cells porosity, permeability and capillary pressure. Initially conditions capillary stress is due to height above free water level (Ht) and also an Sw might be assigned without understanding resistivity or alternative logged values. This is essential in most pieces of a geomodel not penetrated with a logged nicely and along the nicely track itself whereby the value-added log dimensions offer less certainty to get calculated Sw, e.g. in facies where there is not much comparison between pay and non pay. The Swht equation, such as all specimens, has uncertainty related to its own inputs the significant ones being permeability, interfacial tension, wettability (petroleum ) and sometimes gastrointestinal pressure or elevation.

Ideally the petrophysicist will create the Swht equation, creating and testing it completely within petrophysics before supplying it into the reservoir geologist and reservoir simulation scientist at a seamless fashion as a portion of the frequent usage Reservoir Rock Type Equation Set to get Sw along with other parameters.
