Geothermal Drilling Technology (DRI13)

  • To be announced for 2025


This course provides a comprehensive understanding of the technology and engineering required to successfully design and execute geothermal wells. It covers basic drilling principles analysed from the point of view of a geothermal developer. The geothermal aspects of drilling processes and how they affect the well plan, well construction and overall budget are also presented.

Course Level: Foundation
Duration: 3 days
Instructor: Catalin Teodoriu

Designed for you, if you are...

  • An engineer with little or no background in drilling technology or petroleum science
  • A geologist or any professional involved in geothermal project planning and management

How we build your confidence

The course is structured by presenting the basic drilling technology and then linking it with the features of geothermal drilling activities.
The course will cover the following drilling aspects:
  • Design and evaluation of well drilling systems
  • Identification and solution of drilling problems associated with geothermal wells
  • Mud design for elevated temperatures, well control, casing design
  • Well cementing

Some exercises (drilling costs calculation, casing loads) will be used to highlight the most important aspects of geothermal well construction.
