Unformatted text preview: fracture gradient in units of lb/gal using each of the above three methods. Summarize the results in tabular form, showing answers, in units of lb/gal and also in psi/ft. Fracture Gradients 1.11- 13 Example - Hubbert and Willis 1. Hubbert & Willis: Fmin 1 2P = 1 + 3 D P psi = 0.735 The pore pressure gradient, D ft Fmin 1 psi = ( 1 + 2 * 0.735) = 0.823 3 ft Fracture Gradients 1.11- 14 Example - Hubbert and Willis Also, Fmin = 0.823 psi/ft psi/ft 0.052 lb/gal Fmin = 15.83 lb/gal Fracture Gradients 1.11- 15 Example - Hubbert and Willis 1 P = 1 + 2 D Fmax 1 = (1 + 0.735 ) 2 = 0.8675 psi/ft Fmax = 16.68 lb/gal Fracture Gradients 1.11- 16 Example P K iσ + 2.
