API RP 13B-1
Recommended Practice Standard Procedure for Field Testing Water-Based Drilling Fluids
|Publication Date:||1 December 2003|
This part of ISO 10414 provides standard procedures for the determining following characteristics of water-based drilling fluids:
a) drilling fluid density (mud weight);
b) viscosity and gel strength;
d) water, oil and solids contents;
e) sand content;
f) methylene blue capacity;
h) alkalinity and lime content;
i) chloride content;
j) total hardness as calcium.
Annexes A, B, C and E provide additional test methods which may be used for
k) chemical analysis for calcium, magnesium, calcium sulfate, sulfide, carbonate, potassium;
l)determination of shear strength;
m) determination of resistivity;
n) drill pipe corrosion monitoring.
Annexes D, F, G and H provide procedures that may be used for
o) removal of air;
p) sampling, inspection and rejection;
q) rig-site sampling;
r) calibration and verification of glassware, thermometers, viscometers, retort kit cup and drilling fluid balances.
