Intro The Static Gel Strength Measurement (SGSM) device uses a vaned bob to
condition a cement slurry inside a pressurized test cell and measure static gel
strength at down-hole conditions. By directly measuring the forces required
to initiate movement in the sample, the SGSM provides an accurate way of
determining the static gel strength.
The High Pressure SGSM (#120-58) ts in a high-pressure UCA test cell.
This conguration is compatible with both the Single Cell UCA (#120-50) and
the Dual Cell UCA (#120-52).
The Low Pressure SGSM (#120-53) ts in a low-pressure UCA test cell. This
conguration is compatible with the Twin Cell UCA (#120-51).
In an SGSM test, a vaned bob is submerged in the cement. During the test,
the bob turns periodically and measures the static gel strength of the sample.
A computer running OFITE software graphs the data from both cells. This
data is available in real time on-screen and is also stored in an Excel®
spreadsheet for easy graphical viewing and printing.
- Mechanical measurement of static gel strength
- Conditions the cement in the test cell
- Data is available instantly on-screen and is automatically converted to
Excel®spreadsheet format

Setup
Hardware
1. Carefully remove the instrument from the crate and place it on a at,
stable surface. Make sure to allow for adequate air ow around the unit,
especially near the vents on the sides.
To ensure personal safety, always use proper lifting techniques.
Position the unit so that the user can quickly disconnect plugs in case of
an emergency.
2. Connect the equipment to the computer. Each test conguration requires
a different set of connections to the computer.
-Single UCA or Dual UCA - Connect the UCA to a PC with the
supplied serial cable.
-Single SGSM or UCA/SGSM - Connect the PC and the UCA unit
to the SGSM Data Hub with the supplied serial cables. Connect the
SGSM to the Data Hub with the supplied LPT cable.
When using only the UCA/SGSM software on a dual cell instrument,
always connect the SGSM to Cell 2.
When using the Single UCA or Single SGSM software with a Dual Cell
or Twin Cell UCA, always run the test on Cell 1.
-Dual SGSM - Each SGSM has a Data Hub. Connect each SGSM to
its Data Hub using the supplied LPT cables. Connect the rst Data
Hub to the UCA unit using a serial cable. Connect both Data Hubs to
the computer with serial cables.
Make sure all SGSM electrical connections have been made before
attempting to turn on the SGSM box as this may cause damage to
internal electrical components.
3. Turn the “Main Power” switch on once fully connected to the UCA and PC.

Setup
Software
Before you begin your test, you must prepare the PC to record the data. Five
software applications have been included with your instrument:
-Single SGSM - For running an SGSM test on a Single-Cell UCA
-UCA and SGSM - For running a UCA and SGSM on a Dual-Cell UCA
-Dual SGSM - For running two SGSM tests on a Dual-Cell UCA
1. Turn on the PC, UCA, and SGSM Electronics Box.
2. Open the software by double-clicking the icon on the desktop.
3. Click Utilities → Setup.
“COM Port” - The COM port the device is connected to. The Dual SGSM
software will ask for two COM ports.
“Temp Unit” - °F or °C
“Pressure” - PSI or MPa
The pressure reading is only on the High Pressure 20,000 PSI SGSM
units (#120-58).
“Gel Strength” - Gel strength units (Dyne/cm2, lb/100 ft2, Pa., lb/ft2)
“Unit #” - Identies the unit generating the graph. This eld is helpful
when multiple units are generating graphs.
“Archive Path” - The location to save the data les
“Logo Path” - Select a logo (.JPG format) to print on the graph at the
end of the test.
“Bob Height” - The height of the bob in millimeters
“Bob Diameter” - The diameter of the bob in millimeters

OFITE, 11302 Steeplecrest Dr., Houston, TX 77065 USA / Tel: [phone] / Fax: [phone] / www.ote.com 9
“Conditioning Speed” - The speed (RPM) for conditioning the cement
slurry prior to the SGSM test.
The recommended conditioning speed is 30 RPM. This is equivalent
(based on surface area) to conditioning at 150 RPM in a pressurized
consistometer.
“Conditioning Time” - This is the amount of time the SGSM will
condition the cement before it begins measuring gel strength. This value
must be at least 2 minutes in order to give the SGSM time to establish a
zero offset.
After the Conditioning Time, the SGSM will periodically measure gel
strength based on the “Test Speed”, “Test Time”, and “Wait Time” elds.
“Test Speed” - The speed (RPM) the bob will turn to break the gel and
measure the gel strength of the cement.
“Test Time” - The amount of time the bob will turn while measuring gel
strength.
“Wait Time” - The amount of time the bob will pause between gel
strength measurement periods.
“Strength #1”, Strength #2”, ... “Strength #5” - Enter a gel strength
value in each of these elds. When the cement reaches that gel strength,
the software will record the elapsed time and print it on the graph.
“Print to Printer” - When this option is on, a graph of the test results will
automatically print to the printer when a test is complete.
