Impact/Purpose:
To inform the public.
Description:
• LTV can be used to characterize free phase PCE architecture in 2-D flow chambers without using a dye. • Results to date suggest that error in PCE detection using LTV can be less than 10% if the imaging system is optimized. • Mass balance calculations show a maximum error of 9.6% for the water/air system. • Investigations underway to evaluate differences in answers obtained by LTV measurements for water/air saturation for 20/30 sand. • We are currently evaluating uncertainty in quantifying PCE by LTV.
