ABSTRACT
Three major oil families have been identified based on physical properties,
gas chromatography, liquid chromatography, and gas chromatography- mass
spectrometry. Family A oils are found in Permian-Silurian reservoirs within
the Sorokin swell and Upper Devonian reservoirs within the eastern and
western edges of the Khoreyver depression. This oil family is sourced from
an Upper Devonian bitumen-laminated carbonate mudstone informally known
as the domanik facies. Family B oils are found only in Upper Devonian reservoirs
within the central Khoreyver depression. This oil family is most likely
sourced from Upper Devonian hypersaline marine mudstones with significant
bacterial input. Many of the family B oils were generated at temperatures
less than that for peak oil generation. Family C oils are found in Carboniferous-Lower
Devonian reservoirs within the northern Sorokin swell. This family is sourced
from marine mudstones that have Gloecapsamorpha prisca, as well
as other marine algae, present. Organic-rich Lower Devonian and Silurian
shales contain similar molecular characteristics and are potential sources
for the family C oils.
Oil and rock samples collected throughout the northeastern Timan Pechora
basin identify key oil families and correlate these oil families to stratigraphic
units that sourced them based on distinctive molecular characteristics.
Three distinctive hydrocarbon systems have been identified within the northeastern
Timan Pechora basin. Hydro carbons, both oil and gas, are found in clastic
and carbonate reservoirs from the Lower Silurian to the Triassic.
