| Abstract |
Geology in geothermal development can be divided in surface geology, which takes place mainly before drilling, and well-site geology in conjunction with drilling. Often these activities will take place consecutively, and by different teams. It is important though, for the wells site geologist to be aware of the surface geology, and if necessary to go back (or request others to do so) and re-examine features in the field on the basis of what has been found by drilling. Geotechnical and geohazards geology are discussed separately in this course, but once again the geothermal geologist may be asked to comment on these matters especially at the early stage of project definition when well pad and power plant site options are being considered. |
