WebDrilling down. No one has yet drilled down as far as the Moho, and consequently the mantle. The record for the deepest borehole drilled under the sea for scientific research is currently 3.25km. This was achieved in early 2024, at a site on the Pacific ocean’s Nankai Trough off southwest Japan. The geothermal gradient varies with location and is typically measured by determining the bottom open-hole temperature after borehole drilling. Temperature logs obtained immediately after drilling are however affected due to drilling fluid circulation. To obtain accurate bottom hole temperature estimates, it is necessary for the well to reach stable temperature. This is not …
