Description

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.
