A friend sent these photos of an Eagle Ford Shale well undergoing a pressure test. She first noticed the situation two weeks ago. Yesterday she decided to stop on the side Hwy 77 south of La Grange to take pictures. When she got home, the rubber on the soles of her shoes was melted. Both times she noticed a very strong odor. Last night she experienced health effects from the fumes.
Maybe there is an issue with the casing.
UPDATE: From the comments, I am reminded that shoes have melted before.
