Kjemisk aktiveringssystem for nedihull-verktoey og fremgangsmåte for detektering av svikt ved et oppblåstbart element

摘要

Downhole tools and systems can be actuated chemically by placing a chemical sensor downhole and introducing a chemical slug into fluids being pumped downhole. When the slug reaches the sensor a reaction in the sensor may be employed to trigger an event (e.g., actuation) or may cause a count to increase by one on its way to a full count and actuation of a tool or system downhole.
