... that had never been used in the area were applied, such as oil based mud (OBM), electromagnetic measurement while drilling (MWD), rigless cement evaluation, PDC bits and cased hole evaluation. These logging systems were chosen because of the high risk of losing openhole wireline tools as a result of fluid...
