Quantitative production logging of openhole and horizontal wellbores presents a challenge for conventional logging tools and techniques. The complicating factors of horizontal logging are primarily related to low fluid velocities and stratified flow. Openhole horizontal completions increase the opportunity for tool fouling and fill obstruction, creating abrasive running environments, and complicating interpretation with unknown hole geometries. To address these challenges, a new diverter logging system that uses inflatable packer technology was developed.
