... perforations connecting to fractures and hence perforation cluster efficiency. Our method requires a shut-in procedure with abrupt drops in injection rate to produce water hammer oscillations (tube waves propagating between the wellhead and current stage). The rate drop is accompanied by a drop in wellhead...

..., it is beneficial to identify key metrics for interpretation. We selected to capture cluster efficiency (% of clusters that exceed a target threshold volume), equivalent entry points per 10,000’ (number of clusters that met the target volume), heel/toe bias metric (an indication of stage distribution), and standard...

... size was highly variable, even with oriented equal-entry charges. Because of high pre-fracture treatment variability, it is not recommended to use an average diameter of unstimulated perforations to evaluate cluster efficiency of perforations post-fracture treatment. Ideally, perforations should...

The data gathered quantified the perforation diameter, perforation erosion range, perforation orientation dependency, cluster efficiency, perforation erosion bias, and discovered the presence of significant casing damage around areas where plugs were set. The image results showed...
