The American Petroleum Institute (API) Recommended Practice 13B-2 (RP 13B-2) establishes recommended practices for field testing oil-based drilling fluids. OFITE offers equipment for testing oil-based drilling fluids based on this document.
- Density (Section 5)
- Mud Balance, Metal (#115-00): Measures density in lbs/gal, specific gravity, lbs/ft3, and PSI/1000 ft. The rugged, stainless steel design is perfect for field or laboratory use.
- Density (Section 6)
- Pressurized Fluid Density Scale (#100-70): Works on the same principle as the standard mud balance, but it incorporates a plunger for pressurizing the fluid sample.
- Viscosity an Gel Strength (Section 7)
- Marsh Funnel Viscometer (#110-10): Measure funnel viscosity.
- Model 800 Viscometer (#130-10-C): This viscometer is powered by DC voltage, which makes it ideal for international use. The included power supply works with available power in any country.
- Model 900 Viscometer (#130-76-C): The Model 900 is a full-featured viscometer that can operate with a computer or as a standalone instrument. The variable speed motor ranges from .01 to 1000 RPM. With the ORCADA® software, the user can build and store custom, automated tests.
- Static Filtration (Section 8)
- HTHP Filter Press, 175 mL (#170-181): For testing up to 350°F (175°C) per Section 8.2.
- HTHP Filter Press, 500 mL (#171-191): For testing above 350°F (175°C) per Section 8.3.
- Retort Test for Oil, Water, and Solids Concentrations (Section 9)
- Electrical Stability Test (Section 11)
- ES Meter (#131-50): Determines electrical stability by applying a precision voltage-ramped sinusoidal signal across a pair of parallel flat plate electrodes that are immersed in the fluid.
- Measurement of Shear Strength Using Shearometer Tube (Annex A)
- Shearometer Kit (#166-08): Includes two tubes and a cup with a graduated scale
- Shearometer Tube with Weight Support (#166-10): Standalone
- Determination of Oil and Water Retained on Cuttings (Annex B)
- 50 mL Retort Kit: The only size of retort recommended for testing cuttings.
- Determination of Aniline-Point Temperature of Base Oils (Annex D)
- Aniline Point Determination Kit (#145-80): Includes a stirring hot plate, support rod, glassware, and reagents.
- Chemical Analysis of Active Sulfides by the Garrett Gas Train Method (Annex I)
- High-temperature/High-pressure Filtration Testing of Drilling Fluids Using the Permeability-plugging Apparatus (PPA) (Annex K)
- Sand Content Procedure for Non-aqueous Fluids (Annex M)
- Identification and Monitoring of Weight-material Sag (Annex N)
- Surface Monitoring of Weight-material Sag (Section N.3)
- Dynamic Weight-material Sag Test - VSST Method (Section N.5)
