The Current Status of Wellbore Stability Research in Geothermal Drilling

https://doi.org/10.54691/d41qr045Keywords:
Wellbore stability; drilling fluid density.Abstract
Wellbore stability is crucial in geothermal drilling as it guides the setting and selection of many parameters, such as drilling fluid density, fracture pressure, drill bit speed, and well trajectory. However, it is unfortunate that research on wellbore instability in geothermal drilling is limited. The future large-scale development of higher temperature geothermal resources will require further study of wellbore instability, particularly under harsh conditions in different regions and rock layers. Additionally, improving and predicting wellbore instability is essential for enhancing efficiency and reducing costs during the drilling process.
