Question

What is the range of depth of most Hydro thermal wells?

(a) 600 – 2100m

(b) 50 – 60 m

(c) 8 – 10 km

(d) 1200 – 5400m

I had been asked this question during an internship interview.

This intriguing question comes from Hydrothermal Systems in portion Ocean Energy & Geothermal Energy of Energy Engineering

Answer 1

Right option is (a) 600 – 2100m

For explanation: Most hydrothermal wells range in the depth from about 600 to 2100 m, although there are some shallower and deeper production wells. As already mentioned for practical purposes hydrothermal resources are further subdivided into vapor dominated and liquid dominated types.
