After successfully retrieving the 5 inch casing a reamer
Rig at sunset.

After successfully retrieving the 5 inch casing, a reamer run was started to clean the open hole prior to coring. When the bit reached the measured depth of 3194 meters, which is the depth of one of the active faults that offset the casing in the main hole, we had considerable difficulties. When pullijng the drill string from the open hole, a stabilizer in the bottom hole assembly became stuck at the top of the window milled through the casing. Operations are underway to free the pipe.
