French term or phrase: Carotte de fond

In an "End of exploration drilling report"
" Des cutting ont été prélevés tout le long du puits (sauf dans les zones à perte de circulation). L'échnatillonnage a été intégré par 14 carottes de fond et 10 carottes latérales."

"Les carottes de fond suivantes ont été prélevées:" follows a list of depth intervals, with % of recovery, lithology and formation)

Reference: Subsoil investigations

Reference information:
When investigating the subsoil and wishing to obtain core samples, you can either core the full depth (done for major infrastructure projects such as dams where information about every centimetre of depth is important) or you can rotary (destructive) drill to the depth you feel might be of interest, as in mineral prospection for instance, take a core sample from the bottom of that hole, then drill deeper if necessary and repeat the operation as many times as necessary, or you can drill a hole to the full depth envisaged, take a bottom core sample (from the bottom) and subsequently, if required, take sidewall core samples (carottage latéral à balles - CLAB) at other depths down the hole.

Unless drilling upwards or horizontally, a "conventional" or axial core sample is necessarily a bottom core sample at the time it is taken.

For info:
Sidewall coring (carottage latéral À BALLES):
A coring technique in which core samples are obtained from the hole wall in a zone that has already been drilled. a hollow BULLET is fired into the formation wall to capture the core and then retrieved on a flexible steel cable. core samples of this type usually range from 3/4 to 1-3/16 inches (20 to 30 millimeters) in diameter and from 3/4 to 4 inches (20 to 100 millimeters) in length. this method is especially useful in soft-rock areas.

Note to reference poster

Asker: Thank you so much Bourth. You actually provided the answer I was after. The others, (even the right one!), sounded too much like guesswork.
