Indeed, while TBJH was initially discovered in 2021, scientists only measured its depth down to 900 feet due to limitations in the echo-sounder technology — which calculates speed based on sound ...
Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and obtained a large sample ...
The Bertha Rogers Borehole is a former natural gas well in Burns Flat, Dill City, Oklahoma, US.Today plugged and abandoned, it was originally drilled by the Lone Star Producing Company as its oil-exploratory hole number 1–27 between October 25, 1972 and April 13, 1974, reaching a then world record terminal depth of 31,441 feet (5.9547 mi; 9,583 m).
