High pressure, high temperature. HPHT is where the undisturbed bottom hole temp at prospective reservoir depth or total depth is greater than 300oF or 150oC, and either the maximum anticipated pore pressure of any porous formation to be drilled through exceeds a hydrostatic gradient of 0.8 psi/ft, or a well requiring pressure control equipment with a rated working pressure in excess of 10000 psi.
