---|---|
~300 m | GPK-1 |
Very local fault with almost no apparent fault offset | |
Mud logging: nothing observed | |
Log cutting: nothing observed | |
~750 m | Local fault from the surface to the Kutzenhausen boundary fault which has a 100 m fault offset |
Mud logging: caliper and temperature anomalies | |
Log cutting: nothing observed | |
~1083 m | Soultz-sous-Forêts Fault from the surface down into the granitic basement with approximately 100 m cumulated fault offset |
Mud logging: between 1042 and 1049 m several caliper anomalies, variations in neutron porosity, temperature and bulk density | |
Log cutting: Couches Intermédiaires reduced about 29.5 m in comparison with Rittershoffen | |
~1116 m | Mud logging: nothing observed |
Log cutting: nothing observed | |
~1233 m | Mud logging: anomalies in temperature and ROP, and between 1219 and 1240 m total mud losses which involves a permeable fault at 1219 m |
Log cutting: anhydrites filling, Couches de Rehberg twice reduced in comparison with Rittershoffen (33 m instead of 79.5 m) | |
~1316 m | Mud logging: nothing observed |
Log cutting: nothing observed | |
GPK-2 | |
~266 m | Local fault from the surface to the Kutzenhausen boundary Fault with 100 m fault offset |
Mud logging: nothing observed | |
Log cutting: a fault with a small vertical offset in an unconsolidated unit (Couches de Pechelbronn) is not necessary visible, moreover it is the uppermost unit therefore already eroded at the top | |
~708 m | Soultz-sous-Forêts Fault from the surface down into the granitic basement with approximately 330 m cumulated fault offset |
Mud logging: little gas peak | |
Log cutting: nothing observed | |
~733 m | Mud logging: nothing observed |
Log cutting: nothing observed | |
~766 m | Mud logging: nothing observed |
Log cutting: nothing observed |
