Pickett plot for water resistivity
Webb30 okt. 2011 · Abstract. A practical method, based on the pattern recognition approach used in Pickett plots, is presented for preliminary yet accurate quantitative evaluation of shale gas formations. The method is inspired by a quick-evaluation, time-tested methodology developed by Passey et al. (1990) for shales, which utilizes primarily sonic … WebbFigure 9 plots the resistance versus strain for the through-thickness samples, and Figure 10 plots the calculated bulk material resistivity versus strain of four through-thickness samples. Bulk resistivity (ρ) is calculated at each strain level using the measured resistance values (R), the contact surface area of the sample at the electrical contacts …
