Dataset for: Well-scale multiphase flow characterization and validation using distributed fiber-optic sensors for gas kick monitoring

This dataset contains the fiber optic Distributed Temperature Sensor (DTS) and Distributed Acoustic Sensor (DAS), and frequency band energy (FBE) data collected from well-scale experiments conducted at Louisiana State University (LSU), in January 2020. Two-phase experiments consisting of nitrogen gas injection in circulating or static water column were conducted on a 5025 ft deep test-well at LSU. Gas rise signatures were observed at different injection volumes, circulation rates, backpressure conditions, and injection methods (through tubing or injection line).
