  • Automated Gas Porosimeter

    Porosity is the percentage of empty space within a solid media. Effective porosity is the percentage of void space in which the pore spaces are interconnected. Accurately determining the effective porosity of a petroleum reservoir is important for estimating the total amount of recoverable hydrocarbons within a producing formation. The BLP-630 Automated Gas Porosimeter was designed to rapidly and accurately measure the effective porosity of a core sample. Three separate volumetric gas reservoirs provide seven (7) possible gas volume combinations to improve effective pore space data for a broad range of core sizes and porosities. It includes an assortment of volumetric core holder inserts to minimize dead space for greater accuracy. And the core holder is secured and release with a quarter turn by hand for quick and easy core loading. During a test, a core sample is placed into the air- ...

  • 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 ...
