Advanced environmental technologies for increasing coal seam permeability

本项目旨在了解煤层气开采过程中天然裂缝中良性化学物质相互作用、溶解矿物和煤表面的物理/化学机制。在澳大利亚，提高煤的渗透性技术已成为具有商业可行性的煤层气开采所必需的技术。传统天然气行业现有的方法对煤炭来说是有问题的，而且无法利用煤炭现有的裂缝网络。预期的项目成果是一系列新的煤炭专用技术，以提高渗透率，避免对煤层造成不必要的和不可逆转的破坏，并保护环境。结合降低成本，这些方法将有利于澳大利亚CSG行业的可持续发展。

This project aims to understand the physical/chemical mechanisms occurring when benign chemicals interact and dissolve minerals and coal surfaces in the natural fractures during the extraction of coal seam gas. Technologies for increasing the permeability of coal have become necessary for commercially viable coal seam gas (CSG) extraction in Australia. Currently available methods from the conventional gas industry, are problematic for coal, and fail to capitalise on coal’s existing fracture network. The intended project outcome is a range of new coal-specific technologies for enhancing permeability that avoid unwanted and irreversible damage to seams and protect the environment. Combined with reduced costs, these methods would benefit sustainable growth of Australia’s CSG industry.
