In status updates to Office of Conservation, Texas Brine reports:
Work ongoing to improve rig road west of sinkhole to allow for installation of vent well (ORW 5) and geophone well (G 03) and provide sinkhole containment
Continuing site construction for G 03, rig scheduled to begin moving in Jan. 30
Continued making geotechnical borings on Texas Brine facility in preparation for installation of permanent sinkhole containment system
Southern alignment of planned containment system 90 percent cleared, 3,000 yards of sand placed to allow access
