... ABSTRACT: Enhanced Geothermal Systems (EGS) offer significant potential for clean energy extraction from hot rock formations. However, maintaining high flow circulation, maximizing heat extraction, and minimizing thermal losses remain major challenges. This study presents a modeling...

... of the ground subsidence rate. In order to ascertain the extent of ground subsidence resulting from oil and gas extraction and to consider the impact of creep in rock formations, it was necessary to conduct a comprehensive study. In this paper, we analyse the data from creep experiments on underground shale...

... lines unless deemed safe at closer distances. To balance safety with economic considerations, a detailed geotechnical risk assessment was performed to reduce this distance without compromising safety. This practical study is pivotal in optimising coal extraction while ensuring the integrity and safety...

... ABSTRACT: Historically, secondary pillar extraction has been successful in the soft rock mining environment. Several hard rock platinum mines have conducted selective remnant extraction with backfill as a regional support measure. A hard rock tabular platinum mine instigated the extraction...

.... These formations, located deep underground with high temperatures but low permeability, require innovative engineering to extract heat. The process involves circulating a fluid to transport heat to the surface, thus enabling power generation. The key to utilizing HDR lies in the generation of a conduit path...

... ABSTRACT Studies have shown that up to 85% of total shale gas-in-place could be adsorbed gas. Thus, how much more adsorbed gas can be extracted will significantly impact the ultimate gas recovery. In recent years, the concept of using thermal stimulation to enhance shale gas recovery has been...
