    Prediction of coalbed methane productivity based on neural network models by JIN Yi, ZHENG Chenhui, SONG Huibo, MA Jiaheng, YANG Yunhang, LIU Shunxi, ZHANG Kun, NI Xiaoming

    Published 2025-01-01
    “…Finally, according to the classification results, combined with the actual drainage data, the BP and LSTM neural network algorithms were used to predict the daily gas production of CBM wells.ResultsThe results show that: (1) Based on the grey correlation method model analysis, 10 parameters such as permeability, gas saturation and reservoir pressure gradient in the study area are the key factors affecting the gas production performance of coalbed methane; (2) Using fuzzy mathematics evaluation method to evaluate the enrichment of coalbed methane, the gas production effects of 34 wells in the study area is divided into three categories: favorable area, relatively favorable area and unfavorable area. (3)A coal reservoir daily gas production prediction model was established based on the LSTM algorithm, with a prediction error value between 4.06% and 14.79%, and the average error value of 11.09%. …”

    Explainable Offline‐Online Training of Neural Networks for Parameterizations: A 1D Gravity Wave‐QBO Testbed in the Small‐Data Regime by Hamid A. Pahlavan, Pedram Hassanzadeh, M. Joan Alexander

    Published 2024-01-01
    “…In contrast, offline training of this NN in a small‐data regime (18‐month) yields unrealistic QBOs. However, online re‐training of just two layers of this NN using ensemble Kalman inversion and only time‐averaged QBO statistics leads to parameterizations that yield realistic QBOs. …”
