API RP 13B-1
Recommended Practice for Field Testing Water-based Drilling Fluids
Organization: | API |
Publication Date: | 1 March 2009 |
Status: | inactive |
Page Count: | 104 |
scope:
This part of ISO 10414 provides standard procedures for determining the following characteristics of water-based drilling fluids:
drilling fluid density (mud weight);
viscosity and gel strength;
filtration;
water, oil and solids contents;
sand content;
methylene blue capacity;
pH;
alkalinity and lime content;
chloride content;
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-pluggin
- example of a report form for water-based drilling fluid.
