Production logging in highly deviated and horizontal are known to be challenging. While conventional array tools have improved to provide answer in some wells, challenge remain with very long tool strings and limitation of sensors. The presentation will introduce a new instrumentation technology using microelectro-mechanical system (MEMS). The technology offers an ultracompact and modular array flow sensor platform, with up to 10 times reduction in tool string length, along with introduction of novel measurements. A series of examples from deployments in various continents are shown highlighting the potential of the of technology.
