Abstract: Non-fungible tokens (NFTs) can be generated and stored on a digital ledger for use in controlling ownership of well log data in some examples described herein. In one such example, a system can encrypt well log data to generate encrypted well-log data. The system can then generate a new record that associates a non-fungible token with the encrypted well-log data, where the non-fungible token is usable to track ownership of the well log data. The system can then publish the new record to a digital ledger that is distributed among a plurality of computer nodes of a ledger network. The new record can be published to the digital ledger in response to at least a subset of the computer nodes reaching a consensus decision to add the new record to the digital ledger.

Abstract: Real-time data from one or more sensors can be received about one or more active wellbore operations. A blended data set can be generated that includes the real-time data combined with historical data about previously completed wellbore drilling operations, and associated with performance attributes. Additionally, identification of a criteria of focus, types of parameters for optimization, and operation groupings for the blended data set can be received. Further, the criteria of focus, types of parameters for optimization and operation groupings for the data can be applied to the blended data set to determine an adjustment for an active wellbore drilling operation of interest. The adjustment for the active wellbore drilling operation of interest can be outputted.
