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 all new 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.

OFI Testing Equipment, Inc. will be exhibiting at the Abu Dhabi International Petroleum Exhibition and Conference November 13 – 16 at stand 7432 hall 7. Stop by and see our Model 2040 Automated HTHP Consistometer, which tests the thickening time of oilwell cement at up to 40,000 psi and 500°F. We will also be showing our single cell Ultrasonic Cement Analyzer and Static Gel Strength Measurement Device (which measure the compressive strength and gel strength of cement over time).

We will also be discussing our partnership with Salunda Limited to distribute the new MudChecker, a solid state probe that measures the oil, water, and solids content as well as salinity of oil based drilling fluids in just a few minutes. A Salunda representative will be on hand to answer questions and provide hands-on demonstrations. We are excited about the opportunity to bring this new technology to the drilling fluids testing industry.

The mechanical properties of a material describe how that material behaves when subjected to an applied force. When placed in an oil well, cement is subjected to numerous stresses which impact its ability to both protect the casing and maintain zonal isolation. Lateral stresses within the formation threaten to warp and crush the casing. Expansion and shrinkage caused by temperature and pressure cycles cause brittle cement to develop cracks, which place well integrity at risk as the cement debonds from the casing or formation.

There are four primary mechanical properties of cement that oilfield service companies need to understand to predict the behavior of the set cement under downhole stresses:

Cement in an oil well needs to be able to resist the forces found in the formation in order to protect the steel casing around which it is placed. The cement sheath is also required to support the weight of the casing as well as resist perforation operations conducted by wireline operators in preparation for fracturing and stimulation activities. Cement needs to develop an adequate level of compressive strength in order to meet these requirements.

Cement compressive strength describes the ability of hardened cement to resist crush force. Laboratories have multiple options to measure the compressive strength development of a cement design. The most practical and efficient method to accurately calculate the compressive strength is to use an Ultrasonic Cement Analyzer (UCA). The UCA works by sending a continuous sound pulse into the cement slurry. As the cement hardens, the sound pulse travels faster through the cement matrix. The transit time is correlated to the compressive strength of the hardened cement.
