January 26, 2011
TG3 / WG3Particle Size Distribution Testing of
OBMs/SBMs
• Surveyed varied PSD instruments in global usage: Malvern, Beckmann Coulter, Cilas, Microtrac, as major parties
• Members discussed perceived relevant issues: dispersion solvents, dilution solvents, use of ultrasound, % obscuration, optical model selection, sample homogenization.
January 26, 2011
TG3 / WG3Particle Size Distribution Testing of
OBMs/SBMs
• Agreed that a clear description of what assumptions are inherent in the guidance given in the proposed RP will be necessary.
• Determined need to establish a basic lab prepared system for Round Robin testing.
January 26, 2011
TG3 / WG3Particle Size Distribution Testing of
OBMs/SBMs
• Members discussed wettability concerns of the wide possible variety of solids present in these fluids.
• Homogenization methods were discussed and the limits and expectations of sample uniformity was discussed.
January 26, 2011
TG3 / WG3Particle Size Distribution Testing of
OBMs/SBMs
• Found that % obscuration values were highly varied among users and may lead to agglomerated stated even when diluted.
• Members discussed limiting initial RP scope to fully dispersed state samples.
• Call for submission of individual methods for detailed comparison.
January 26, 2011
TG3 / WG3Particle Size Distribution Testing of
OBMs/SBMs
New Business:
• Request TG guidance on limiting initial RP scope to fully dispersed sample systems.
• Discuss new parameters to ensure proposed RP would be general enough in focus so as not to exclude any existing instruments in usage.
January 26, 2011
TG3 / WG3Particle Size Distribution Testing of
OBMs/SBMs
New Business (Continued):
• Discuss HSE issues regarding flammable solvent use in PSD measurements, including rig-site use.
• Request TG guidance on desired timeline for proposed RP delivery and any need to alter WG composition to meet.
January 26, 2011
TG3 / WG3Particle Size Distribution Testing of
OBMs/SBMs
New Business (Continued):
• Submit individual PSD methods for review and variability comparison.
• Distribute proposed Round Robin testing formulation for member review.
• Other items to be determined

Old BusinessAction Items From June Meeting In Washington, DC
January 26, 2011
Hand out revised SR3 to Task Group
Measurement of NAF Internal Phase Activity Modifiers
January 26, 2011
Background: Increased emphasis on environmental aspects of drilling fluids is driving fluid companies toward non-chloride internal phase activity modifiers for non-aqueous fluids
