Drilling Fluids Testing

For Drilling Fluids testing, Fann sells testing equipment as individual instruments and in convenient kits.

Activity

Activity

Activity is the measurement of the chemical potential or the reaction availability of a chemical species. Hole conditions in water sensitive shales can be correlated with changes in the activity of emulsified water in oil-based drilling fluids using these kits.
DF Aging/Roller Ovens

Aging/Roller Ovens

Drilling fluid aging is the process in which a drilling fluid sample, previously subjected to a period of shear, is allowed to more fully develop its rheological and filtration properties.
DF Blenders and Mixers

Blenders and Mixers

Preparation of drilling fluids and samples used in fluid analysis requires a variety of high speed mixers and blenders. These mixers must conform to American Petroleum Institute Specification 13A and require the API recommended single mud impeller blade for mixing either water-based or oil-based drilling fluids. These mixers can also be used to mix cement for field or laboratory testing.
DF Corrosion Monitoring

Corrosion Monitoring

Placing corrosion test rings in the drill string is a common technique to evaluate the corrosiveness of drilling fluids on the drill string and other steel equipment. Examination of these rings after they have been downhole for some time, can be highly informative as to the corrosiveness of the drilling fluid and the type of corrosion encountered.
Density/Mud Balances

Density/Mud Balances

You'll find mud balances on any drilling site. Fann has rugged, accurate, and portable balances.
Differential Sticking

Differential Sticking

Differential testing determines stuck pipe tendency and the effectiveness of spotting fluids in any given drilling fluid.
EP and Lubricity Test

EP and Lubricity Test

The lubricity test is designed to simulate the torque and drag produced by a given drilling fluid down-hole.
Electrical Stability

Electrical Stability

The electrical stability (ES) of an oil-based drilling fluid is related to the stability of the emulsion and oil-wetting capability.
Field Testing

Field Testing

When a series of tests is needed at the drilling site, Fann Porta Lab includes the entire range of instruments necessary. The kits are enclosed in rugged, durable cases, built to withstand harsh conditions.
DF Filtration

Filtration

Measurements of the filtration behavior and wall-cake-building characteristics of an oil mud are fundamental tests. Fann has a full line of fitration testing equipment.
Methylene Blue

Methylene Blue

The Methylene Blue Test determines the amount of reactive solids in a fluid sample, based on the cation exchange capacity of the solids.
Permeability Tests

Permeability Tests

This measurement is useful in predicting how a drilling fluid can form a permeable filter cake to seal off depleted/under pressure intervals.
Resistivity

Resistivity

Resistivity meters measure the resistivity of fluids, slurries or semi-solids. These solid state electronic instruments are designed to meet the needs of field and lab personnel for resistivity measurement according to API procedure.
DF Retorts

Retorts

Instruments for testing water, oil and solids content in drilling fluids. These tests are fundamental to proper control of mud properties such as: oil/water ratio, rheology, density, filtration and salinity of aqueous phase.
Sand Content

Sand Content

A simple, accurate and inexpensive sieve analysis apparatus for determining the sand content of drilling muds.
DF Shale Testing

Shale Testing

Problems such as stuck pipe, tight hole, washout, and sloughing can be related to shale stability. Tests used to determine if a specific shale is likely to cause problems include the capillary suction time (CST) test and the linear-swell meter (LSM) test.
DF Viscometers and Rheometers

Viscometers and Rheometers

These instruments measure the viscosity of drilling fluids.
Water, Oil, and Solids

Water, Oil, and Solids

Knowledge of water, oil and solids content is fundamental to proper control of mud properties. Fann has field kits to make the measurements.
