Sampling and Characterization of Difficult Fluids

Volatile hydrocarbon fluids in low permeability porous media can present challenges when trying to sample and characterize correctly. This course explores phase behavior fundamentals that identify where problems arise and how to remedy these difficulties for both oils and gas condensate reservoirs, including some where more than one phase exist in situ.
