What is XLOT Application in Nankai Drilling about?

1) An extended leak-off test (XLOT) was conducted during a scientific drilling project in the Nankai Trough to estimate the minimum principal stress at depth. 2) An XLOT involves pressurizing the borehole beyond the initial leak-off pressure to induce fracture formation and propagation. By analyzing the pressure changes over time, values like the fracture closure pressure can be estimated, which represents the minimum principal stress. 3) The first successful XLOT conducted from a riser drilling vessel l
