Evaluation of Reconstruction Potential for Low-Production Vertical Wells of CBM in the Southern Qinshui Basin

open access: yes, 2023
Production practice has shown that not all low-production coalbed methane (CBM) wells can be reconstructed into high-production wells through secondary stimulation, so it is necessary and timely to establish an evaluation index system, form an evaluation

Readout Electronics for CBM-TOF Super Module Quality Evaluation

open access: yes, 2023
A super module assembled with MRPC detectors is a component of TOF (Time of Flight) system for the Compressed Baryonic Matter (CBM) experiment. Before the super modules are applied to CBM-TOF, their quality needs to be evaluated.

A new quantitative evaluation method for development area selection of tight gas and CBM commingled production

open access: yes, 2019
Existing evaluation methods used for the development area selection for commingled production of tight gas and coalbed methane (CBM) are poorly universal and their parameters (e.g. reserves and reservoir physical properties) cannot reflect the production
