The driving of the outer 20” casing is completed… The driving of the 17” casing is expected to start today. After that is completed, 10” casing will be driven (which is expected to reach the salt) and then 7” will be driven to the cavern itself. This will be a timely process.
The helicopter flyover was not done yesterday to observe the site due to the heavy lightning we experienced but John just took off and I hope to have some video soon. An onsite observation on yesterday showed no additional sloughing of land on the perimeter of the sinkhole.
