Viscosity

The Viscometer Sag Shoe Test (VSST) is a well site and laboratory test that measures the weight material sag tendency of field and lab-prepared drilling fluids under dynamic conditions. The VSST provides an intrinsic fluid property without regard to the conditions under which the fluid has been or will be used. As such, results must […]

The OFITE Measuring Cup is graduated in fluid ounces (2 – 32 oz) and cubic centimeters (100 – 1,000 cc) and is designed to be used with the OFITE Marsh Funnel Viscometer. The heavy duty plastic measuring cup features a double spout and has the two scales molded into the inside of the cup for […]

Viscosity and gel strengths are measurements that relate to the flow properties of fluids. The Marsh Funnel Viscometer has been used for many years to obtain an indication of the relative viscosity of drilling fluids (known as Funnel Viscosity). It is calibrated to outflow one quart (946 mL) of fresh water at a temperature of […]

The Double Walled Circulating Cup is designed to cool a fluid sample below ambient temperature while taking viscosity readings. Features Designed for testing below ambient temperature Compatible with Refrigerated and Heated Bath/Circulator (#152-55 / #152-55-1) Includes removable stainless steel cup (#130-38-7) Size: 4.5″ × 4″ × 6″ (11 × 10 × 15 cm) Weight: 2 lb 3 […]

This 20 gram shearometer tube with weight support is used for testing heavier muds and is specifically designed for testing high gel strength drilling fluids. It is common for 10 minute gels to reach 35 lb / 100 ft2. Drilling conditions and economics will determine the need to reduce gel strengths. Part Number #166-10 Instruction […]

An alternative measuring device used in determining the gel strength of a drilling fluid is the Shearometer. The set includes two 5-gram, 3.5″ x 1.4″ hollow shear tubes and a sample cup with a graduated scale mounted in the center of the cup base. The scale measures gel strength in pounds per 100 square feet. […]

The OFITE Universal Heat Cup is designed for controlling the temperature of a fluid sample while taking readings with a rheometer or viscometer. Normal heat-up time is 15 minutes and the pilot light turns on during heating. Features Designed to work with the Model 900 Viscometer Can be plugged directly into the Model 900 Viscometer, […]

The Thermocup is designed for controlling the temperature of a mud sample while taking readings with a viscometer. The holes in the stage of OFITE Viscometers have been positioned to hold the heated cups at a 45° angle to the line of the instrument for better accommodation of thermometers and power cables. A removable stainless steel cup (included) makes cleaning […]

The Hand Crank Rheometer is a direct-indicating, manually operated, rotational viscometer. The instrument is powered by a hand crank, which drives the spindle through a precision gear train. The shift cam selects between fixed speeds of 300 and 600 RPM. A Knob on the hub of the shift cam determines gel strength. Features Suitable for […]

It is extensively used worldwide in both the field and laboratory for precisely measuring the rheological properties of drilling fluids and cement. Learn more about what makes the Model 800 Viscometer unique. Features Speeds are easily changed with a […]

The Model 900 Viscometer is a true Couette coaxial cylinder rotational oilfield viscometer, which employs a transducer to measure the induced angle of rotation of the bob by a fluid sample. For a fully automated Control/Data Acquisition System suitable for research applications, the Model 900 Viscometer may be connected to a computer via a serial […]

For enhanced data collection, OFITE is pleased to introduce its new Pressurized Viscometer. This fully-automated system accurately determines the fluid characteristics of stimulation fluids, completion fluids, drilling fluids, and cement in terms of shear stress, shear rate, time, and temperature at pressure up to 2,500 PSI. Using the exclusive ORCADA® software, a computer novice can operate […]

For extremely high temperature and / or high pressure viscosity measurements, OFITE offers the HTHP (or HPHT) Viscometer. This fully-automated system accurately determines the rheological properties of completion fluids and drilling fluids in terms of shear stress, shear rate, time, and temperature at pressures up to 30,000 PSI and temperatures up to 500°F. An optional […]
