This project aims to understand the formation, geometry and fluid connectivity of unconventional high-temperature and high pressure shale gas reservoirs using volumetric instabilities of ductile materials. Unconventional shale gas/oil are the most abundant fossil fuel resources on Earth, but are inaccessible to conventional techniques. This project will investigate the mechanisms, critical parameters and applicability of the theory to unconventional reservoirs. It will do so by testing the theory under controlled laboratory experiments, fully coupled thermo-hydro-mechanical-chemical (THMC) modelling and analytical modelling. The outcomes should allow a rigorous assessment of the potential of unconventional reservoirs under Australia’s extreme conditions.

该项目旨在利用韧性物质的体积不稳定性来了解非常规高温高压页岩气藏的形成、几何结构和流体连通性。非常规页岩气/油是地球上最丰富的化石燃料资源，但常规技术无法获得。本项目将研究该理论的机理、临界参数及其在非常规油藏中的适用性。它将通过受控实验室实验、完全耦合的热-水-机械-化学(THMC)模型和分析模型来测试该理论。这些结果应该能够对澳大利亚极端条件下非常规油藏的潜力进行严格的评估。
