Special Issue Information
Dear Colleagues,
Drilling performance in unconventional reservoirs is a critical key factor for the production’s economic profitability. Unconventional reservoir formations present many challenges due to their diverse geomechanical properties. These properties can lead to excessive coupled drilling vibrations (Axial, Lateral, Torsional), which cause significant non-productive time (NPT), bad borehole quality, and reduced rate of penetration (ROP). While vibration control approaches are being implemented for conventional reservoir drilling, innovative approaches are highly needed for unconventional reservoirs. On the other hand, recent research has demonstrated a promising accumulation of natural hydrogen worldwide, necessitating advanced exploration activities, including geophysical surveys and exploration drilling. Since ultramafic rock drilling can induce severe vibrations and increase NPT, it is necessary to explore how to mitigate such unwanted dynamics toward ensuring economically profitable hydrogen production.
This Special Issue aims to publish the most recent advances in drilling vibration control designed for unconventional reservoirs, geothermal wells, and perspectives for hydrogen exploration.
Topics of interest for publication include, but are not limited to the following:
- All aspects of drilling challenge modeling related to Axial, Lateral, and Torsional vibrations in unconventional reservoirs, geothermal wells, and natural hydrogen exploration.
- Geomechanical properties studies linked to drilling.
- Drilling efficiency improvement techniques.
- Case studies of vibration control approaches integrations in unconventional reservoirs.
- Comparative studies and review papers between drilling in conventional, unconventional, geothermal, and hydrogen reservoirs.
- Simulation studies of new concepts in real-time vibration monitoring and control.
- Experimental studies and prototyping.
- Field studies with case studies of new technologies test for vibration mitigation.
- Geothermal wells drilling: challenges and innovations.
- Perspectives of exploration wells drilling for hydrogen reservoirs.
- AI and data-driven approaches for drilling performance improvement.
