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.
