ENVIRONMENTAL IMPACTS OF CLOSURE PRACTICES IN MINING AND OIL EXPLORATION: STRATEGIES FOR REHABILITATION AND SUSTAINABLE DEVELOPMENT

Geophysical monitoring of geological carbon dioxide storage sites (CCS) represents an indispensable component for validating long-term safety and permanence. However, mathematical modeling of the seismic response to CO₂ injection faces challenges that fundamentally exceed the conventional frameworks of exploration geop...

Techno-Economic Analysis of Repurposing Abandoned Oil Wells for Geothermal Energy Extraction Using Physics-Informed Neural Networks

To achieve net-zero targets by 2050, it is critical to diversify renewable energy. Hydropower, wind, and solar energy dominate; geothermal energy remains underutilized. Conventional Enhanced Geothermal Systems (EGS) rely on hydraulic stimulation, which poses risks such as induced seismicity. To address this, Closed-Loo...

A Review of Numerical Models for Predicting Subsidence in Abandoned Mines (2015–2025)

Abstract Subsidence in abandoned mines presents significant geotechnical and environmental risks, threatening infrastructure, ecosystems, and human safety, often decades after mining activities have ceased due to the gradual collapse or deformation of underground voids. This process can result in structural damage, soi...

Physics of Failure Remaining Life Assessment for Safe Geothermal Repurposing of Legacy Wells

The increasing population of legacy and orphaned oil and gas wells represents a mounting well-management challenge for industry, regulators, and society. Beyond age alone, the barrier system degrades through corrosion, debonding and micro-annulus formation, and fluid migration, raising methane-emission risk, groundwa...

Hydraulic Fracturing in Coal Seam Gas Reservoirs, Lessons and Challenges from the Surat Basin, Australia

The paper presents a review of the specific rock mechanical challenges of hydraulic fracturing in coals with extremely high Poisson's Ratios. The efficacy and potential limitations of fracture stimulations are reviewed in context of twenty years of fracture design optimisation in context of analytical and regional ge...

Transformer-Based Surrogate Model for Prediction of Hydraulic Fracture Geometry

We developed a computationally efficient and accurate surrogate model to assess key descriptors of fracture geometry during reservoir stimulation associated with unconventional subsurface energy scenarios. The work is motivated by the observation that accurate quantification of fracture length, width, and height is k...
