Abstract
Systems and methods for extracting and analyzing formation fluids from solids circulated out of a subterranean formation are provided. In one embodiment, the methods comprise: providing a sample of formation solids that have been separated from a fluid circulated in at least a portion of a well bore penetrating a portion of a subterranean formation at a well site; performing a solvent extraction on the sample of formation solids using one or more solvents at an elevated pressure at the well site, wherein at least a portion of one or more formation fluids residing in the formation solids is extracted into the one or more solvents to produce an extracted fluid; and analyzing the extracted fluid at the well site to determine the composition of the extracted fluid.
