  • 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 ...

  • Join Us at ADIPEC

    OFI Testing Equipment, Inc. will be exhibiting at the Abu Dhabi International Petroleum Exhibition and Conference November 12 – 15 at stand 7510 hall 7. Stop by and see our latest technology and learn about new products and services. We will be showing the new MudChecker, a solid-state probe that measures the oil, water, and solids content as well as salinity of oil based drilling fluids. A Salunda representative will be on hand to answer questions and provide hands-on demonstrations. We have also invited Sequoia Scientific to exhibit with us and show off their LISST-Portable | XR particle size analyzer. It is the only portable laser diffraction particle size analyzer in the world. We will also be showing our new Model 4005 Automated Twin Cell UCA with SGSM. We hope to see you there! ...

  • 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 ...

  • A Better Way to Retort

    The Retort is designed to measure the percentage of oil, water, and solids in a sample of drilling fluid or cuttings. This percentage is crucial for controlling mud properties, such as rheology, density, filtration, and salinity. And knowing the solids content of your drilling mud is essential for evaluating viscosity control and solids control equipment. The new Multi Unit Retort combines five 50 mL Retorts into a single unit. Each Retort has its own electronic temperature controller and an ergonomic stand for holding the receiver tube (also known as JP Tube). This compact design not only fits under a fume hood, but it also saves valuable and scarce bench space. For more information, visit the product page. ...

  • Space Still Available for October Drilling Fluids Training

    Oil drilling is complex. It combines many different technologies and disciplines. Rig teams today must have extensive knowledge of drilling fluid chemistry as well as testing equipment to effectively drill a well. We are proud to host a drilling fluid training program, taught by industry experts, that covers all aspects of drilling fluids technology. This course emphasizes both theory and practical application, with both classroom lecture and hands-on laboratory exercises. Classes are held at the OFITE facility in Houston, TX. Lead instructor is David Breeden, a consultant with over 35 years of experience in all aspects of drilling fluids technology, marketing, R&D, and operations. He is joined by Larry Mitchell, who has over 20 years of experience with drilling fluids testing equipment and technology. The next class will be October 1st through 5th, 2018. Space is still available, ...
