Abstract

Coal fines can substantially influence coal seam gas reservoir permeability, thus impeding the flow of gas in coal microstructure. The coal fines generation and migration are influenced by several factors, wherein coal fines are generally hydrophobic and aggregate in natural coal seam gas (CSG) under prevailing conditions of pH, salinity, temperature and pressure. This aggregation behaviour can damage the coal matrix and cleat system permeabilities, leading to a considerable reduction of proppant pack conductivity (i.e. fracture conductivity). Several datasets have been reported within the literature on this subject in the last decade. However, a more up-to-date discussion of this area is key to understanding coal fines migration and associated knowledge. Thus, in this review, we conduct a systematic investigation of coal fines and their influencing factors. Here, coal fines are introduced, followed by an initial holistic investigation of their generation, plugging, movement, redistribution and production. Then, in order to enhance current understandings of the subject matter, a parametric evaluation of the factors noted earlier is conducted, based on recently published literature. Subsequently, the published mathematical and analytical models for fines generation are reviewed. Finally, the implications and challenges associated with coal fines mitigation are discussed.
