PRACTICAL COMPANION TO RESERVOIR STIMULATION
EXAMPLE E-10
Solution (Ref. Section 8-2.7)
Net Pressure Control
Equation E-42 can be rearranged:
Assuming that the net pressure during the fracture propaga- 2.4 x 106Apf4 (1 - v)~ hf4
tion described in Example E-9 must be maintained below 800 9i = (E-48)
psi to control fracture height migration, what should the G "xf
injection rate be at the 1500-ft fracture half-length point?
and thus
(2.4 x 106)(S004)(0.753)(904)
'
4. = 12BPM. (E-49)
