  • Introducing the OLR

    At OFITE we are excited to announce a new product for rheology testing. The OLR Series 1000 OnLine Rheometer is designed to continuously measure, plot, and report the flow properties of process fluids in the pipe. It provides instant and accurate rheological data in real time so that during manufacturing and processing, liquids are produced and maintained within specification. The OLR is designed for use in a pipe. It continuously measures and relays the data to the process operator, either through the software (SOLR) or through a factory PLC (Process Logic Controller). The plant operator or engineer input specific flow property data for the product being tested to establish the optimum production specification parameters. The OLR monitors the process and displays the product conformance throughout the manufacturing and production process. The OLR uses a squeeze-flow technique. It meas ...

  • AADE Paper Discusses OFITE Automated System

    The American Association of Drilling Engineers (AADE) has published a new technical paper discussing three new OFITE products and a pilot program to test the system in a real-world environment. The OFITE Automated System (OASys) was deployed on an active land drilling rig deployed on multiple multi-well pads, over a six-month period. The AADE paper describes the system and shares data and results, discusses inline and near line measurement of the rheological profile, and shares lessons learned and thoughts on future developments. OFITE OASys is an innovative solution for the real-time measurement and reporting of drilling fluid properties. All three instruments included in OASys sit on the rig where they can sample the drilling fluid directly. The measurements are then sent to the rig data information system where it is used for simple real time calculations for predicting hole cleaning ...

  • 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 ...
