Field Testing Water-based Drilling Fluids, Fifth Edition, Includes Errata 1 (2020), Errata 2 (2021), and Errata 3 (2023) — 132 стр.
This recommended practice provides standard procedures for determining the following characteristics of water-based drilling fluids:

a) drilling fluid density (mud weight);
b) viscosity and gel strength;
c) filtration;
d) water, oil, and solids contents;
e) sand content;
f) methylene blue capacity;
g) pH;
h) alkalinity and lime content;
i) chloride content;
j) total hardness as calcium;
k) low-gravity solids and weighting material concentrations.

Annexes A through K provide additional test methods that 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, timers, viscometers, retort cup, and drilling fluid balances;
  • permeability plugging testing at high temperature and high pressure for two types of equipment;
  • sag testing.
