Examination of last night's downhole data revealed what we expected; the bottom of the casing strays from vertical quite sharply. This has been the cause of our core barrel snags this past week. A mill bit and 30 feet of stiff rods are due to arrive in a couple days, and with these tools we will drill straight down through the casing. In the meantime, drillers will perform maintenance on the drill rig and other site equipment, and the science team will finish preparations for when we receive core.
