1. A method for completing a wellbore traversing a subterranean formation, the method comprising:
(a) making electromagnetic resistivity measurements along a lateral section of the wellbore;
(b) evaluating the resistivity measurements to estimate a water content of the subterranean formation along the lateral section of the wellbore; and
(c) fracturing the formation at selected regions along the lateral section at which the water content is below a threshold and avoiding regions at which the water content is above the threshold,
wherein (c) further comprises (i) cementing a casing in the lateral section of the wellbore, (ii) setting first and second packers to isolate one of the selected regions at which the water content is below the threshold, (iii) perforating the casing in the isolated region, and (iv) pumping high pressure fracking fluid downhole from surface to fracture the subterranean formation in the isolated region.
