• Improvements to the Salunda MudChecker

    The MudChecker, from Salunda Ltd., is quickly becoming one of the most talked-about instruments in the drilling fluids industry. This handheld, solid-state device provides oil, water, total solids, and salinity measurements in a simple, two-step process. It also measures high-gravity and low-gravity solids with no chemicals and no heating elements. The results are accurate, repeatable, electronic, and traceable. The latest release of the MudChecker, version 1.5, now offers standalone operation. All calculations are now performed on onboard, with no software and no internet connection required. This exciting new feature makes it easier for remote technicians and rig personnel to take measurements in areas where the internet is not accessible. The MudChecker is currently being used in labs and in the field in parallel with standard API testing while providing high-frequency measurements, ...

  • A Bigger Retort in a Smaller Package

    Everyone in the drilling fluids industry is familiar with the oilfield retort. It measures the volume of oil, water, and solids in a sample of drilling mud. They come in three sizes – 10 mL, 20 mL, and 50 mL – and are often included in field portable kits. Typically, the retorts included in kits are the smallest size, 10 mL. But OFITE has changed that. We have developed a 20 mL retort chamber that fits into the same heating jacket as the 10 mL retort chamber. This gives you a choice of sample volumes in your field kits. And since it fits in the same heating jacket, you can easily switch sizes by changing the chambers and cups. While the 10 mL has traditionally been the most space-efficient Retort, the 20 mL provides a higher level of measurement precision. That is why many users opt for the larger sizes in the lab, but use the smaller, more portable sizes in the field. To order a comp ...

  • pH Testing of Drilling Fluids

    In chemistry, pH is a measure of the concentration of hydrogen ions in an aqueous solution. pH is measured on a scale from 0 to 14. A pH of less than 7 indicates an acidic solution, while solutions above 7 are considered alkaline. A pH of 7 is neutral, as in the case of pure water. pH analysis is fundamental to drilling fluid control. The pH of the fluid affects clay dispersion and the solubility and effectiveness of chemical additives. A change in pH while drilling often indicates contamination by substances such as cement, gypsum, or carbon dioxide. Effective corrosion control and treatment depends upon the proper pH adjustment. There are two accepted methods of measuring pH: the colorimetric method using paper strips and the electronic method using a pH meter and electrode. Colorimetric Method This method is popular because it is quick, easy, and inexpensive. A strip of paper is p ...

  • A Cost-Effective Reservoir Permeability Tester

    Permeability is a measure of the ability of a fluid to flow through a porous media when subjected to a differential pressure and is mathematically equated by Darcy’s law. The permeability of a petroleum reservoir is one of the most influential parameters in determining the production capabilities of a producing formation. Our Reservoir Permeability Tester was developed to evaluate how fluids affect the permeability of a core specimen. In addition, the unit may be used to evaluate acidizing techniques and to develop typical Acid Response Curves (ARCs). The Reservoir Permeability Tester (part number 127-00) features a Hassler-type core holder that rotates 90° to allow either horizontal or vertical testing. Manual valves enable forward and reverse injection through the core for up to three separate fluids and Nitrogen gas. All wetted components are made of 316 stainless steel, although Has ...

  • Repair, Maintenance, and Calibration

    The oil field is finally busy again! We’re all excited to see business ramping up and people getting back to work. As you load up for that next job, take a look at your mud testing equipment. Is it still in good condition? Does it need repairs, maintenance, or calibration? If so, OFITE can help. We offer full-service repair, maintenance, and calibration on virtually all mud and cement testing equipment. We offer competitive rates and fast turnaround times to get you back up and running in no time. Even if we didn’t manufacture it, we can fix it. We can also bring our services to you. The OFITE service van makes regular trips to West Texas, South Texas, and Louisiana, with other regions available in the future.
