... as the flow rate of produced water increases with a significant jump beyond the critical flow rate observed at mobility ratio of 1. Similar results corroborating above were obtained with variation in skin factor. This model therefore can be used to diagnose, evaluate and simulate mobility ratio and skin...

... coefficient and a reference rate, to quantify the non-Darcy flow in reservoirs accurately. The traditional non-Darcy skin factor, generally applied to model the non-Darcy flow in reservoirs, is employed to describe the non-Darcy flow across completions only. This study shows that the non-Darcy flow effect may...

... test data analysis requires two plots to directly obtain all the parameters of interest. The formation permeability and the non-Darcy flow coefficient are obtained from the first plot, whereas the skin factor is obtained from the second analysis plot. This work systematically illustrates...

... Abstract Numerical simulation was used to verify that properly conducted deliverability tests in gas wells would yield reliable values for permeability, skin factor, non-Darcy parameter, and stabilized well performance coefficient. Furthermore, the correctness of pseudostabilization time, used...
