Methods for the calculation of true formation factors in the bunter sandstone of northwest england

Worthington, Paul F. / Barker, Ronald D.

Abstract A laboratory investigation of the electrical properties of the Bunter Sandstone from the Fylde area of northwest Lancashire has demonstrated that measured values of the formation factor exhibit a marked variation with the concentration of the saturating electrolyte, presumably as a result of the conducting influences of the rock matrix. The method of least squares is used to represent this variation in terms of specified first- and second-order equations. From these expressions a true formation factor can be calculated. The field application of this parameter in hydrogeological studies of these sandstones is briefly discussed and exemplified.
