With help from horizontal wells and hydraulic fracturing, shale gas has made a significant
contribution to the energy supply. However, due to complex fracture networks and
complicated mechanisms such as gas desorption and gas slippage in shale, forecasting
shale gas production is a challenging task. Despite the versatility of many simulation
methods including analytical models, semi-analytical models, and numerical simulation,
Decline Curve Analysis has the advantages of simplicity and efficiency for hydrocarbon …
