Abstract
Production logging is difficult in complex well designs such as<br>horizontal multilateral (ML) wells with jagged level-two exits.<br>The ML exits can obstruct the access of logging tools due to<br>damage around the milled windows. Once inside a low-flow<br>high-water cut reservoir, the challenge becomes measuring an<br>oil inflow profile in stratified flow.
