The Electrical Stability (ES) of an oil-based drilling fluid is directly related to its emulsion stability and oil wetting ability. The Emulsion Stability Meter determines ES by applying a precision voltage-ramped sinusoidal signal across a pair of parallel flat plate electrodes that are immersed in the fluid. The resulting current remains low until a threshold voltage (61 ± 5 μA) is reached. Then the current rises very rapidly. The point at which the fluid becomes conductive is the peak volts measured when the current reaches the 61 μA point.

The OFITE Advanced ES Meter offers an improved probe connection to prevent damage, embedded software for advanced testing, thermocouple, and multiple power options (batteries, AC/DC power, USB).

Designed for long distance shipping, the International Kit is enclosed inside a portable case with reinforced handles and latches. The storage area is divided into three main sections. The top tray contains a glassware storage area with protective shipping containers for pipettes and all testing reagents. The middle tray area contains a portable mixer, marsh funnel and cup, pressuring assemblies for the high-temperature / high-pressure filter press, a hot plate, cup heater, 30 minute timer, and pocket balance. In the large bottom section is the Model 800 Viscometer, 10 mL retort, API filter press, the HTHP heating jacket, and a complete Offshore Test Kit in a stainless steel case. Also included is a Mud Balance, pH meter, and hand-crank centrifuge. Commonly needed spare parts have been included for all assembled items.

Any lab that runs high-temperature, high-pressure filtration testing has to be concerned with safety. Heated and pressurized test cells, if handled improperly, can injure people and damage equipment. Yet if they are handled properly, they are as safe as any other equipment.

The Safety Clamp is designed to hold an HTHP filtration cell securely in place and prevent any uncontrolled pressure release. The two plates clamp the cell in place while the locking screws (also known as grub screws) are removed. Pressure can then be released gradually and safely.

Our very own Shannon Bryant will be presenting a paper at the AADE Fluids Technical Conference and Exhibition next week. He will be discussing our latest innovation in cement expansion/shrinkage testing.

We will also be exhibiting at the show. Stop by and see us in booth 27 to learn about our latest products. We will be showing the cement mold for measuring expansion/shrinkage, our all-new Advanced Digital Wettability Tester, and the Model 800E Viscometer. We will also have some precision pumps from our partner, Teledyne ISCO on display.

The show is April 7 and 8 at the Marriott Marquis in downtown Houston.

We hope to see you there!

The Benchtop Consistometer is designed to determine the thickening time of well cements under simulated down-hole pressures and temperatures. It can also be used to easily condition well cements under temperature and pressure for further API testing. Its compact, lightweight design makes the unit ideally suited for benchtop use.

We recently upgraded the Benchtop Consistometer to include a touchscreen display. It contols the test temperature and displays and graphs temperature, pressure, and consistency. It can also be used to program custom temperature profiles for more advanced testing. And you can now run the Consistometer in standalone mode, in addition to using it with a computer.

03/20/2026

The Bulk Hardness Tester is designed to evaluate the hardness of shale after exposure to fluids. The hardness of the shale can be related to the inhibitive properties of the fluid being evaluated. Shale that interacted with the fluids will become softer due to the adsorption of water, swelling, and dispersion of fine particles. This rock-fluid interaction can be linked to wellbore stability problems, including reduction in the compressive strength, spalling, or fracturing. In terms of integrity of drill cuttings, excessive softening and stickiness of the pieces of shale can produce mud rings in the annulus, sticking problems in the drilling assembly, and bit balling, among other problems.
