Abstract
Accurate evaluation of remaining oil can be effectively complemented with production logging data in a horizontal well for a<br>successful workover. The pulsed neutron tool has been used for production profile measurements in complex stratified flow<br>regimes in horizontal wells for some years using water flow log and three-phase holdup log measurements.
