... is 1.0, permeability becomes a function of formation factor only. Water saturation and apparent formation factor are the parameters that can be calculated from well logs. When water saturation and apparent formation factor are known, permeability can be estimated from the suggested relationship. Data...

... diameter, and surface area can be computed from well log data. These correlations can be used to predict formation permeability for high permeable formations; however, they often do not provide accurate estimates in low permeability reservoirs. In practice, a correlation model for low permeability shaly...

In development wells, however, DST's are typically scarce, and hence J must be estimated from well logs. The log-based...
