(Waters No. 3 and Mackey No. 1.) not only a possibility for structural correlations, but at times enables one to recognize beds which may otherwise be overlooked. Figure 36 represents two resistivity logs obtained with the Schlum- berger method of electrical coring in two wells % mile apart near Oklahoma City. In this figure, the resistivities are plotted in log- arithmic scale. It is seen that the two curves are very similar in almost 484.
