Question

DETERMINE THE MAXIMUM RATE (BPM) AND SURFACE PRESSURE (PSIG) THAT CAN BE USED FOR THE FOLLOWING WELL WITHOUT FRACTURING THE RESERVOIR.
DEPTH 8,000'
FRACURE GRADIENT 0.65 PSI/FT

TUBING 2-3/8" 4.7#
CASING - 7" 26#
TREATMENT FLUID 15% HCL
15% HCL VISCOSITY AT 72?F
WELL SPACING 40 ACRES (RE = 660)
HOLE SIZE = 9"
TREATMENT INTERVAL (H) - 50
NO. OF PERFS 50 WITH 2 JSPF
FORMATION PERMEABILITY 10 MD
STATIC BOTTOM HOLE PRESSURE 2100 PSI
Hints
ACID S.G. =
VISCOSITY = CP
FRICTION LOSS = PSI/1000'@ 1 BPM







Q=.00708*10md*h*(change)P/(1*(viscosity)*ln(660/.0375)) = B/D

ANSWER: ________ BPM @ ________ PSIG
