Challenges, models, and algorithms for flow and transport simulations in deep reservoirs

open access: yesDeep Underground Science and Engineering, EarlyView.
Deep reservoirs are considered a promising resource for future energy supply, but current reservoir simulation technologies may face certain challenges if they are directly used in specific scenarios in deep reservoir development. Models and algorithms were developed to resolve these challenges, including a better phase equilibrium model, a better ...

Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

open access: yesDeep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Mechanical property variation mechanisms of granite subjected to real‐time high temperatures and subsequent cooling treatment

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates the coupled thermo‐mechanical behavior of granite during heating and cooling through a combination of laboratory tests and finite element analysis. The thermal conductivity, mineral composition, mass loss rate, micro‐crack observation, and thermal fracture characteristics of granite under various temperature conditions are ...
