Geothermal Drilling Technology (DRI13)

    Description

    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 Level: Basic to Intermediate
    Instructor: Catalin Teodoriu

    Designed for you, if you are...

    • An engineer with little or no background in drilling technology or petroleum science

    The course requires a minimum knowledge of fundamental science.

    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: 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.

    The benefits from attending

    By the end of the course you will feel confident in your understanding of:

    • The basics of drilling engineering related to geothermal applications
    • The interdependency between geothermal well drilling and the oil & gas business
    • The specific tools needed to drill a well in general and specifically for geothermal drilling
