Hi Francesco,
I would imagine that CHT is way too expensive (and slow). A good deal of
work has been performed with DHT via the seismic cone. You should contact
the NGI group ("Tom Lunne" <[log in to unmask]>) and ConeTec ("David Woeller" or
"Ilmar Weemes" at ConeTec Investigations Ltd. <[log in to unmask]>).
Sincerely,
Paul
