To our knowledge, no prior studies have attempted to quantitatively integrate DTFM and low-frequency DAS to obtain estimates of fracture geometry. The resulting correlation between fracture opening and fiber...

The test setup is illustrated, detailed test steps are discussed, and experimental data with correlations of rate per perforation and discharge coefficient is presented. Completions tested included 4-1/2", 5", and 5-1/2" casings in common weights...
