  • All New Cement Constant Speed Blender

    The Constant Speed Blender is designed to prepare a cement slurry by mixing it at constant speeds according to API guidelines. The blender begins by mixing at 4000 rpm for 30 seconds. It then increases the speed to 12000 rpm for 60 seconds. As the slurry thickens, the onboard controller continuously adjusts the current to the motor in order to maintain the proper mixing speed. The new Model 25 Constant Speed Blender from OFITE brings you the same functionality as the older Model 20 Blender in a more compact, economical package. The timer and speed controls are now integrated into the blending unit, eliminating the need for a separate control box. The result is a smaller, lighter unit that takes up less space in your lab and is easily portable. To learn more about this exciting new product, visit the product page. ...

  • New Automated UCA/SGSM

    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. The Model 4005 has a maximum pressure of 5,000 psi and a maximum temperature of ...

  • Introducing the Mud Watcher

    We are excited to announce the addition of a new product to our catalog. The Mud Watcher continually monitors and displays the density, viscosity, and temperature of any drilling fluid (mud, brine, completion fluid, etc.) used on a rig. It sends all data directly to the rig data acquisition system, mud logging unit, or dedicated data acquisition system. The Mud Watcher reduces the risk to rig personnel while providing more accurate, reliable information for better decision making. Since the Mud Watcher can be operated unattended, it is no longer necessary for personnel to enter the shaker shack multiple times a day to take samples. This reduces their exposure to potentially hazardous conditions, such as high temperatures, hydrocarbon gas, or even H2S. Traditionally, drilling fluid on a rig is collected and tested every 15 to 30 minutes. With so much time between samples, localized prop ...

  • One Year After Harvey

    Tomorrow, August 25, is the one-year anniversary of Hurricane Harvey. The wind, storm surge, intense rain, and unprecedented flooding that followed devastated the Houston area and many communities along the Texas gulf coast. OFITE has always been proud to be a part of the Houston community. Our roots here go deep. And we shared in the heartbreak and pain of the region as we watched the terrible events unfold. This weekend, we want to remember the tragedies of the storm and celebrate the triumphs of our families, friends, neighbors, coworkers, and partners who faced the unthinkable, and remained, as always, #HoustonStrong. Many victims of Hurricane Harvey are still in need of assistance. If you would like to contribute, here is a list of organizations still helping those in need: Hurricane Harvey Relief Fund Rebuild Texas Fund Houston Habitat for Humanity United Way of Greater Ho ...
