170 Well Logging and Formation Evaluation
Exercise 11.4. Horner Analysis
A well is tested under the following conditions:
Flowing period = 24 hours
3
Production rate = 200stm /day
B o = 1.2
h = 10m
r w = 0.1m
f= 0.25
m= 1cp
C = 0.00031/bar.
After the flowing periods, the well is shut in and the following pres-
sures recorded downhole as shown in Table 11.5.2.
Using the data, determine the initial reservoir pressure and the
permeability.
