petroleum eng. well log.

5. The heading of the electric log given in below Figure lises the following information Total depth 9.500 Maximum recorded temperature - 168F Rm, at 168F -0.56 m Mud weight- 11 lbm/gal Estimate the formation water resistivity and salinity for the bottom permeable Zone A SPORTUREDES-POTETIT Bc }B (If it is not clearly visible, bottom depth given in the figure is 8500 t. point is at 5400 ft) 6- The Rt and R xo values of a very thick, permeable bed are 10 and 40 N.m, respectively. Assume that the borehole effect can be neglected and that di = 20 in Determine the reading of the LLs, and the LLD from the related chart
