ONLINE: Geothermal Drilling Technology (DRI913)


    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.

    Course Structure: 6 modules of 2 hours each, delivered over 3 days
    Each day will consist of 2 modules which will be no more than 2 hours in length with multiple breaks.

    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

    • This is a basic to intermediate level course and requires a minimum knowledge of fundamental science.

    How we build your confidence

    • The course is constructed as a live instructor-led training with case studies, videos, and exercises presented during class.
    • 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: the 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.
