Drilling Rig Strikes Salt Mine Drains Lake
If you have never seen this video this is a must watch.
Lake Peigneur was completely drained when the drill string struck the salt mine below
Something Was Not Right
So on November 21, 1980, there was this drilling rig hired on by Texaco on Louisiana’s Lake Peigneur. Drilling away they noticed a large torque spike & suddenly their string was stuck. The drill string had torqued up while drilling below the surface of the shallow lake.
The rig crew attempted to free the drill string. A series of loud pops were heard & their platform begin to tilt toward the water. Alarms were sounded & the men evacuated to the shore. They had no idea what was about to go down. For the lake was about to transform as they knew it.

An hour and a half later, the men watched their $5 million, 150-foot-high derrick somehow vanish into a lake. Keep in mind that the lake had an average depth of less than three feet. Jimmy the roughneck was not too good at math was quoted saying “that ain’t right.”
It seems their drill had accidentally penetrated a main shaft of the Diamond Crystal salt mine! The salt mine had various tunnels which crisscrossed the rock under the lake. Lake water was now rushing into the mine through the rapidly expanding 14-inch hole in the salt dome. With a force ten times that of a fire hydrant.
Fifty miners were racing the rising waters, using mine carts and an agonizingly slow elevator to exit the mine eight at a time. Watching the water rush in beneath them

Amazingly, the miners all escaped, but the drama was just beginning for Lake Peigneur. The rig hands watched in shock as the water began to circle around its new “drain,” making the lake into a swirling vortex of mud, trees, and barges, the largest man-made whirlpool in history.
A tugboat, a dock, another drilling platform, a parking lot, and a big chunk of nearby Jefferson Island got sucked into the abyss.

Lake Peigneur used to drain into Vermilion Bay via the Delcambre Canal, but once the lake had emptied into the mine, the canal changed direction and salt water from the Gulf of Mexico flooded into the muddy lake bed.
(To this day, Lake Peigneur has a brackish ecosystem very different from the way it was in 1980.) The backwards flow created a temporary 164-foot waterfall, the tallest in the state, and 400-foot geysers burst periodically from the depths as compressed air was forced out of the flooded mine shafts.
Again Jimmy was quoted again commenting “that ain’t right.”

The drilling companies eventually agreed to pay $45 million to the owners of the mine and other flooded local businesses.
Why were they digging for oil directly above an active salt mine? you might ask. Didn’t they know? They did!
The Texaco platform was drilling in the wrong place because of a mapping mistake: an engineer mistook transverse Mercator projection coordinates for UTM coordinates.
