Figure 4-12. Hyper-Delta Mode Option
4.4.3.5 Variable Logging Mode Option
The Variable Logging Mode shown in Figure 4-13 is used to set up special logging modes like a
simulated logarithmic logging rate used in pump or slug tests on a well. There are six different
time periods in this mode and each can be set for a different logging rate and length.
Select Rate X:
The top half of the screen has six boxes labeled “Select Rate 1” to “Select Rate 6”. Each
box represents a time period and allows the logging rate for that time period to vary
independently from the other time periods.
The top item in each box is the current logging rate for the specified time period.
