Key words: mountain building, migration, sequence of stratigraphy, light
and heavy oil, Timano-Pechora province.

The actual material and exploration data indicate that the spatial distribution
of reservoirs in the carbonate complexes of the Pechora shelf is controlled
by structural forms. In addition, a tectonic factor has a significant impact
on the safety of hydrocarbon accumulations and their properties.
