BS EN ISO 10414-1:2008

This standard BS EN ISO 10414-1:2008 Petroleum and natural gas industries. Field testing of drilling fluids is classified in these ICS categories:

• 75.180.10 Exploratory, drilling and extraction equipment

This part of ISO 10414 provides standard procedures for determining the following characteristics of water-based drilling fluids:

1. drilling fluid density (mud weight);

2. viscosity and gel strength;

3. filtration;

4. water, oil and solids contents;

5. sand content;

6. methylene blue capacity;

7. pH;

8. alkalinity and lime content;

9. chloride content;

10. total hardness as calcium.

Annexes A through K provide additional test methods which may be used for

• chemical analysis for calcium, magnesium, calcium sulfate, sulfide, carbonate and potassium;

• determination of shear strength;

• determination of resistivity;

• removal of air;

• drill-pipe corrosion monitoring;

• sampling, inspection and rejection;

• rig-site sampling;

• calibration and verification of glassware, thermometers, viscometers, retort-kit cup and drilling-fluid balances;

• permeability-plugging testing at high temperature and high pressure for two types of equipment;

• example of a report form for water-based drilling fluid.
