  • Slotted Filter Disks

    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. Slotted filter disks come in two sizes. The ¼” thick disks fit where the ceramic filter disk fits. They can include either 1 or 3 equal slots with no taper. The slots are the same size on both side ...

  • Automated Gas Permeability Testing

    Most benchtop permeability testers are manually operated instruments with lots of valves and switches. The operator has to stand next to the instrument during a test to set pressures and record results. The Automated Gas Permeameter makes testing the permeability of reservoir core samples simple and easy. It features two auto-switching mass flowmeters for measuring the flowrate of gas through the core. The included software automatically switches between the two flowmeters to suit the needs of the test, providing greater accuracy over the full measurement range. The Automated Gas Permeameter also includes a quick-access core holder with a stationary core boot. This makes loading a care fast and easy, and significantly reduces the turnaround time of a test. Also, the software controls the confining and inlet pressure on the core, freeing the operator to perform other tasks. To learn mo ...

  • The Cost Savings of Automation

    Drilling fluids are critical to maintaining well safety and quality during construction and completion. That makes drilling fluid properties key control parameters of the drilling and completion process. Moreover, increased efficiency of new drilling technology, and demand for data driven by digital advances in remote monitoring and analytics require frequent and reliable measurement of the physical and chemical properties of drilling fluids. Typically, these properties have been measured by manual field sampling and testing. But manual testing lags advances in drilling efficiency, causes delays, and is susceptible to bias, inconsistencies, and inadvertent human errors. Mud properties must be monitored and adapted as drilling progresses to total depth. These properties are not only critical to the safety and efficiency of the operation, they also provide valuable information throughout ...

  • Four Unit HTHP Filter Press

    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. Not only does the Four Unit HTHP Filter Press save space in your lab, it also saves resources. It has a single pressure inlet and two electrical inlets. One Nitrogen tank and two electrical outlets and run up to four Filter Presses completely independent of each other. And the unit comes with all the accessories (graduated cylinder, filter paper, etc.) necessary to run four ...

  • Electronic Temperature Control

    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. This unit is commonly used on Filter Presses and Thermocups for Viscometers. But it can also be used for hot plates and small water baths. We even have a four-unit version for labs with multiple heating instruments. To learn more, visit the product page. ...
