A production-based model for a fractured well in unconventional reservoirs

Due to the depletion of conventional reservoirs and high demand energy, unconventional will be relied on supply world's energy for foreseeable future. Unfortunately, because their complex storage flow mechanisms, modelling analysis have been very challenging. Although semi-analytical numerical models proposed, these rely somewhat simplifying assumptions require several input parameters. In this paper, a production-based model is proposed analyze predict fractured-well performance in (specifically, tight shale reservoirs). The assumes power law with stretched exponential cut-off. While power-law term governs transient-state period, term, which superposition decays, boundary-dominated period. As result, capable matching both transient state portions data. has validated data applied field Results compared other existing models. findings show that yields relatively good estimates, matches periods. may contribute ongoing efforts improve forecasting reservoirs.
