Real Time Diagnostics of Gas Entries and Remedial Shut-off in Barefoot Horizontal Wells

Accurate diagnostics of wellbore fluid entry is crucial for the<br>understanding of well performance, paramount for reservoir<br>characterization purposes as well as the key element for<br>identifying remedial action for isolation of unwanted fluid<br>entry. Although multiphase production logging can be<br>challenging in horizontal wells, especially in open hole<br>barefoot completions, advances in production logging<br>technology provides more confident results to allow design of<br>shut-off remedial actions that can significantly improve future<br>well performance.
