The research project focuses on developing an advanced drill cutting monitoring system to enhance real-time drilling performance evaluation, particularly in challenging geothermal environments. My core responsibility in this project is to address two critical aspects of geothermal drilling: hole cleaning efficiency and bit wear assessment.

The main objective is to develop an ionic liquid aqueous solution to improve the hydraulic properties of geothermal fluids in enhanced geothermal systems
Develop geothermal working fluids that will NOT precipitate, crystallize, or degrade in EG reservoirs nor production wells.
Develop geothermal working fluids that allow reversibility to take place and the initial permeability of the EGS to be restored.
Develop ionic liquid-based aqueous solutions that respond to temperature change with significant viscosity change.
To reach this objective, the ionic liquid aqueous solution will have:
High thermal stability up to 310 °C.
Suitable viscosity to deliver the desirable hydraulic properties
Reversibility to restore initial permeability
Low cost and environmentally safe

- The main goal of this project was to develop a real time simulation system that reduces geothermal drilling cost and therefore makes geothermal energy more economical, as drilling cost is often the largest expense in geothermal project developments
- The contribution to the geothermal body of knowledge is that a specific hard rock optimization system has been developed that focuses on PDC drilling of geothermal wells
- The new system uses newly developed hard rock Rate of Penetration (ROP) models based on the hard rock-bit cutting process and integrates drillstring vibrations to predict the optimum drilling parameters real time to reduce cost per foot
- Based on the developed ROP models, the drilling process can be optimized either based on maximizing ROP or minimizing Mechanical Specific Energy (MSE)
