For example, a fracture gradient of 0.7 psi/ft [15.8 kPa/m] in a well with a true vertical depth of 8000 ft [2440 m] would predict a fracturing pressure of 5600 psi [38.6 MPa]. See: formation fracture pressure. WebGeologists identify minerals by their physical properties. In the field, where geologists may have limited access to advanced technology and powerful machines, they can still identify minerals by testing several physical properties: luster and color, streak, hardness, crystal habit, cleavage and fracture, and some special properties. molly bulfin mcdonalds
