PRACTICAL COMPANION TO RESERVOIR STIMULATION
EXAMPLE H-3
The area A is
Diverter Cake Resistance
Calculate the required cake resistance to provide a diverter and therefore,
pseudoskin equal to 50. Assume that there are 50 perfora-
tions, with $,@= 0.333 in. [8.46 x m] and L,,.@= 12 in. A = (50) (2) (3.14) (8.46 x (0.3048)
[0.3048 m]. The formation thickness is 20 m, and the perme-
ability is 50 md [4.93 x m2]. = 0.81 m. (H-7)

Solution (Ref. Section 15-5) Finally,
From Eq. 15-3 and rearrangement, (0.81) (50)
Rcrrkc =
(2) (3.14) (4.93 x 10-14) (20)
= 6.54 x 10I2 m-I (H-8)
