The Ultrasonic Cement Analyzer (UCA) uses the change in velocity of an acoustic signal to determine the compressive strength of a well cement over time. The Static Gel Strength Measurement Device (SGSM) uses a vaned bob submerged in the slurry to determine the static gel strength over time. Together, these two instruments provide a more complete picture of the physical properties of a well cement as the slurry sets.

The Model 4005 Automated Twin Cell UCA with optional SGSM automatically controls the temperature and pressure in each cell independently, bringing a new level of precision and control to your cement lab. With the new touch-screen display, you can now run an entire test in standalone mode, without the need for computer software, although the software is still included with the instrument.

Most people who do any kind of mud testing are familiar with ceramic filter disks for filtration testing. The ceramic disk simulates real-world formations and provides greater insight into the filtration characteristics of a mud system than standard filter paper. And filter disks have been the standard for Permeability Plugging Tests for years.

Less familiar are the relatively new stainless steel slotted disks. These disks simulate reservoir formations in a different way. Unlike the ceramic filter disk, which are made from natural material, the stainless steel disks have precisely machined slots for the test fluid to flow through. So, you always know the exact pore size of you filter medium.

We know that space in your lab is valuable. You don’t need bulky equipment taking up more space than necessary. But you also want quality instruments and lots of features. That’s why we developed the Four Unit HTHP Filter Press.

This instrument combines four (4) 175 mL HTHP Filter Presses into a single unit. Each cell has a separate electronic temperature controller and two separate pressure regulators (one for top pressure and one for back pressure). This allows each cell to be heated and pressurized independently.

Do you have equipment in your lab that heats fluid? Do you ever wish you had more precise control of the temperature of those fluids? We thought so. That’s why we developed an all-purpose electronic temperature control unit.

The Temperature Control Unit is a convenient tool for precisely controlling the temperature of an electrical heating device. Simply plug the heating device into the Temperature Control Unit and the built-in electronic controller will regulate the power output to the heater. The controller can be set with either a simple temperature setpoint or an advanced timer.

In a typical well cementing operation, a cement slurry is pumped into the annulus between the well casing and the bore hole. As the cement slurry hydrates, it undergoes a volume change which translates into bulk expansion or shrinkage. Knowing the amount of expansion or shrinkage allows users to design cement systems which can achieve optimal bonding with the borehole and well casing without sacrificing the integrity of the cement matrix. The Circular Cement Expansion Mold is designed to measure the expansion or shrinkage of well cement slurries according to the guidelines in API Recommended Practice 10B-5.

The Circular Cement Expansion Mold has an external ring with a vertical slit on one side to allow it to expand. Before testing begins, the width of the gap is measured with the included micrometer. The expansion mold is filled with a cement slurry and cured in a water bath or curing chamber. As the cement cures, the external ring will expand or contract with the cement slurry. At the end of the test, the gap is measured again to determine the expansion factor.
