Deep unconventional oil and gas reservoirs (such as shale oil/gas, tight oil/gas, coalbed methane (CBM), oil shale, etc.) are commonly characterized by geological and structural complexity, increased formation temperature and pressure, and complex in-situ stress fields. Geomechanics research is helpful to understand the in-situ stress of complex structures, faults and natural fracture systems in deep blocks. Field practice shows that insufficient geomechanics understanding can easily result in low drilling efficiency, long construction period, frequent occurrence of complex situations, and unsatisfactory fracturing effects.
In recent years, geomechanics applied to drilling, completion, hydraulic fracturing, and production in unconventional reservoirs has achieved great progress, producing various advanced experimental and numerical approaches and applications. However, as the buried depth increases, the complicated geology conditions make it more and more difficult for the engineering reconstructions, which poses a great threat to the efficient development of deep resources. New knowledge and understandings of geomechanics are urgently needed to guide the development of unconventional oil/gas reservoirs, and the related theory, experiment and simulation studies are rapidly developing.
The Research Topic aims to gather recent advances, novel insights, and challenges in geomechanics research and application in the effective development of unconventional oil and gas resources. Innovative theoretical, laboratory, numerical, and field studies combined with geomechanics are encouraged. We welcome both original research and review articles.
Potential topics include but are not limited to the following:
- 3D/4D in-situ stress prediction
- Geomechanical Modeling and Characterization
- Wellbore stability and well integrity
- Rock deformation behavior and fracture characterization
- Multiscale mechanical properties of unconventional reservoirs
- Fracture propagation characteristic of deep unconventional reservoirs
- Coupled thermal-hydraulic-mechanical-chemical (THMC) modeling and experiments
- New fracturing technology for deep unconventional reservoirs
- Geomechanical changes from fluid-rock interactions
- Flow characteristics at different scales and multi-scale coupled model
- Productivity prediction and well test model of fracture well
