How a Sinkhole at the Strategic Petroleum Reserve was Contained by a Freezewall in 1995

On Weeks Island in New Iberia Parish there was an incident that is useful to know about.  They had a sinkhole problem there and they fixed it it. The solution included a “freezewall“. Read about it here (15 page doument) –

Mine-induced Sinkholes Over the U.S. Strategic Petroleum Reserve Storage Facility at Weeks Island, Louisiana: Geologic Causes and Effects

2005 Final Report on it from Sandia Labs

It is a big lie when Texas Brine claims their sinkhole problem has never happened before in history. They could have read up on this conference in nearby  Gatlinburg, Tennessee,  April 2-5, 1995, Karst GeoHazards: Engineering and Environmental Problems in Karst Terranes Proceedings of the Fifth Multidisciplinary Conference on Sinkholes and the Engineering and Environmental Impacts of Karst.

The document is also archived now on the Salt Dome page.

  1. Salt cavern construction ‘problems’.
    A number of proposed storage facilities have developed difficulties during development and prior to completion. These are briefly reviewed in the context of potential problems that might be faced when developing storage facilities in the UK.
    Cavern 7, Bayou Choctaw, Baton Rouge, Louisianna
    In 1954, during operations to develop a cavern for storage in the salt dome at Bayou Choctaw, uncontrolled leaching operations led to the collapse of overburden into the developing cavern number 7 (Coates et al., 1981; Neal & Magorian, 1997). A 245 m diameter lake formed and a further cavern (number 4) continues to be monitored following the incident due to fears of collapse due to possible faults in the cap rock (Neal & Magorian, 1997).
    Napoleanville and Clovelly
    Problems have arisen in caverns constructed too close to the edges of the Napoleanville and Clovelly salt domes in southern Louisiana and have resulted in cavern integrity and pressure maintenance problems. This has meant that a number of caverns could not be commissioned (Neal & Magorian, 1997).
    At Clovelly, cavern leaching in the salt overhang meant there was not a sufficient thickness of salt to act as a barrier (Fig. 37). At Napoleanville, shale layers were encountered in some caverns, indicating the salt dome edge and enclosing rocks had been encountered, with insufficient buffer salt remaining (Neal & Magorian, 1997).
    Both incidents point to inadequate site characterisation prior to commencing development and brining operations.

    • Texas Brine’s public statements about “not knowing” what to do because “this NEVER happened before” have got to mean something when they go to court. Those lying dogs!
