Deepest hold in the US is 31,441 feet or so, which would be over 9600 meters. It was drilled near Dill City, OK by Lone Star Oil and Gas Co. and was called the Bertha Rogers #1. Unfortunately, it recovered liquid sulfur (Brimstone). Oil breaks at about 17,000’ depending on the bottom hole temperature. Natural gas is a result and the recoveries can be tremendous, but expensive to develop.
Unless you are in a cool basin like South Louisiana, oil doesn’t make it past 12,000’.
