SGSM
Evaluating Test Data
When a test is complete, the software automatically generates a .jpg file
of the chart and a data file that can be opened in Excel. Both of these files
will be stored in the folder specified in the “Archive Path” field on the Setup
screen (see page 35).
The SGSM data file will show the elapsed
test time, temperature, pressure, and gel
strength at each peak during the test.
This differs from the UCA data file, which
includes data points at a specific time interval
throughout the test.
The SGSM chart shows the temperature,
pressure, and gel strength over time.
The software also generates a trend line
connecting the peaks of the gel strength line.
At the top of the SGSM chart are entries
for “Time @ × lb/100ft^2”. This shows the
calculated time at which the cement reached
each gel strength. These values are set in the
Options screen (see page 35) as “Strength #1”, “Strength #2”, etc.
The “Transition Time” is the calculated time from “Strength #1” to “Strength
#5”. By default, these fields are set to 100 and 500 lb/100ft
2
respectively.
The measurement time for the static gel strength begins at the end of the
conditioning period. These times are interpolated based on the trend line
generated from the peaks that are measured at the end of each “SGSM Test
Period”.
When Multiple Conditioning is on, the Interpolated Data will only reflect data
collected from the first cycle.
