Abstract: A lifecycle history tracking system for assets such as oilfield components and equipment supply uses blockchain technology. Items such as components and assemblies are tracked at various stages that includes recorded environmental data and other information such as testing, certification, transportation conditions, repair, and use conditions. The tracking uses RFID scanners at various stages and each component and assembly has a unique RFID tag. The relevant information is uploaded via nodes maintained by the various parties and added to a common blockchain and the new data is verified by other nodes. Condition based maintenance and improved inventory tracking is facilitated.
