20.6 Reservoir Management Constraints

Reservoir management constraints are presented in Table 20-9, They
include limits on capital expenditures, such as the number of wells that can be
drilled, and operating constraints. In this case, for example, it is considered
important to keep water-oil ratio (WOR) less than five STB water/STB oil. These
constraints are typically imposed by considerations ranging from technical to
commercial. The constraints are especially important in the prediction phase of
the study.

Table 20-9
Reservoir Management Constraints
4 One additional well may be drilled.
4 Completion interval in existing well may be changed.
0 The well is presently completed in entire pay interval.
4 Target oil rate ~ 1000 STB/D
4 Water is available for injection if desired.
4 Limit WOR < 5
4 Minimum allowed BMP = 2600 psia
4 Maximum allowed injection pressure = 5000 psia
4 Minimum economic oil rate =100 STB/D

Exercises

Exercise 20.1 Plot FVF, viscosity, and solution GOR versus pressure for satu-
rated and undersaturated oil.

Exercise 20.2 Verify that the PVT values are properly entered in data set CS-
MB.DAT. What is the bubble point pressure in the model?
