HPHT Direct Indicating Viscometers
Chairperson
Keith Morton / Chevron
WG Charge:
Develop a recommended operating practice for concentric
cylinder viscometers capable of viscosity measurements at
pressures greater than 10,000 psig used to characterize the
rheological properties of WBM and OBM at elevated
temperatures.

TG3 / WG3
Particle Size Distribution Testing of OBMs/SBMs
WG considerations:
•
Wettability of solids
•
Homogenization methods
•
Obscuration values
•
Generalized parameters to avoid exclusion of existing
equipment
•
Adaptability of procedure for use at the rig site – HS&E
issues with solvents commonly used for OBM PSD

TG3 / WG3
Particle Size Distribution Testing of OBMs/SBMs
WG meetings decision:
•
Limit WG scope to fully dispersed sample systems
WG action items:
•
•
•
Review SOP utilized by laboratories as a basis for
establishing procedure for round robin testing
Distribute sample to participating laboratories for round
robin testing
Identify replacement WG chairman as Greg Perez has
a new role at Halliburton/Baroid
June 29, 2011
TG3 / WG4
Measurement of NAF Internal Phase Activity Modifiers
Chairperson
Brent Estes/ Chevron
WG Charge:
Validate activity measurements for estimating
concentrations of activity modifiers in NAFs and
recommend a methodology for using activity
measurements to estimate the soluble activity modifiers to
allow calculations for low gravity / high gravity solids
content in NAFs.

TG3 / WG4
Measurement of NAF Internal Phase Activity Modifiers
Held two work group meetings since Winter SC13
meetings in Fort Worth, Texas
• Established a list of activity modifiers (7) to test.
• Developed round robin test matrix to determine
accuracy and repeatability of hygrometers on
select activity modifiers.
• Next meeting planned for first of August to review
results from 1st round robin tests.
• Recruiting additional members with laboratories to
participate in round robin testing.
