| 3 | Uncertainty quantification in the Permian Basin using conventional and modified bootstrap methodology显示文摘Various uncertainty quantification methodologies are presented using a combination of several deter-ministic decline curve analysis models and two bootstrapping algorithms.These probabilistic models are applied to 126 sample wells from the Permian basin.Results are presented for 12-72 months of pro-duction hindcast given an average well production history of 103 months.Based on the coverage rate and the forecast error(with the coverage rate being more significant in our choice of the best probabilistic models)and using up to one-half of the available production history for a group of sample wells from the Permian Basin,we find that the CBM-SEPD combination is the best probabilistic model for the Central Basin Platform,the MBM-Arps combination is the best probabilistic model for the Delaware Basin,the CBM-Arps is the best probabilistic model for the Midland Basin,and the best probabilistic model for the overall Permian Basin is the CBM-Arps when early time data is used as hindcast and CBM-SEPD for when one-quarter to one-half of the data is used as hindcast.When three-quarters or more of the available production history is used for analysis,the MBM-SEPD probabilistic model is the best combination in terms of both coverage rate and forecast error for all the sub-basins in the Permian.The novelty of this work lies in its extension of bootstrapping methods to other decline curve analysis models.This work also offers the engineer guidance on the best choice of probabilistic model whilst attempting to forecast production from the Permian Basin. | Chukwuemeka O.Okoli Scott D.Goddard Obadare O.Awoleke | 2023 | Petroleum Research2023，8，4： | 0 |
