The analysis of hydraulic fracturing data from a hydraulically fractured vertical gas well in a low-permeability sandstone reservoir and the evaluation of the effective fracture parameters, such as fracture half-length, fracture conductivity, and reservoir properties, were discussed using actual vertical ...
Productivity Index for Unconventional Gas Wells Yousef F. Khajah Productivity Index reflects the ability of a well to produce hydrocarbons and is often used to analyze the well's performance. Productivity Index is the ratio of the flow rate to the drawdown pressure under pseudo-steady state flow ...
In this method, high-pressure gas is injected into the tubing, decreasing the fluid density in the well. This leads to a decrease in the bottom hole pressure and an increase in flow rate18,19,20,21,22. However, high-pressure gas also has huge risks to nearby wells and surface ...

The in-situ generated heat and nitrogen gas during thermochemical treatment can result in removing the water blockage from tight formations utilizing the desiccation effect. Also, thermochemical treatment showed a significant improvement in the core conductivity. The productivity index of core samples ...
