One of the key steps in the data preparation was to align the downhole sensor data spatially and temporally. As summarized in Table 1, DAS, DTS, and the pressure gauges had sampling times of 10 s, 12 s, and 1 s, respectively. The data analyzed in this study was obtained from two-phase (nitrogen gas and water) flow experiments conducted in a 5163-ft deep test-well located in the Petroleum Engineering Research and Technology Transfer (PERTT) lab facility at LSU (Fig.
