Maximizing Estimated Ultimate Recovery from Unconventional Gas Reservoirs: A Decline Curve Analysis Approach
Keywords:
Estimation of Ultimate Recovery , Hydraulic fracturing, Decline curve analysis, Unconventional, GasAbstract
This research investigates the application of decline curve analysis to estimate ultimate recovery and production life of unconventional gas wells. By analyzing production data from 14 wells, including both primary and refractured wells, we aim to quantify the impact of hydraulic fracturing on well performance and reservoir productivity. The study employs the Arps decline curve model to characterize production trends and predict future production rates. The results demonstrate that refractured wells exhibit significantly higher recovery factors compared to primary wells. This finding underscores the importance of hydraulic fracturing as a stimulation technique to enhance production from unconventional gas reservoirs. The insights gained from this study can aid in optimizing field development strategies, maximizing economic returns, and mitigating production decline.
