250               Well Logging and Formation Evaluation

            We are in a Case D situation. The apparent formation dip is given by:


                       -
                            =
                   +
                 .
            a= 6 2 90 95 1 2 degrees from Equation 13.5
                              .
            Using Equation 13.6 with g= 40 degrees we find:
            tan D) =  tan . ) 2  cos(40 ) =  . 0 027
               (
                       (1
            Hence D= 1.57 degrees.
