Baykit Arch

Commentary

The Baykit Arch is remote, although improving regional infrastructure is easing access. However, comprehensive sanctions, including on Rosneft and Lukoil, the seizure of foreign assets and the war in Ukraine make investment impossible for Western companies. Outlook: Negative.

Location

Description

The BAB and surrounding basins, are interpreted to have originated as rifted passive margin basins, which controlled the distribution of upper Proterozoic source rocks, as well as the oil and gas resources. The rifted-passive margin basins underwent compression and deformation during the late Proterozoic (Baikalian orogeny) by collision of continental blocks with the Siberian craton and again during the late Palaeozoic (Hercynian orogeny) by collision of the Kazakh, Siberian, and Eurasian continents.

Summary

Located in central Siberia, access to the basin has been difficult at times due to its remoteness. However, improving regional infrastructure is improving access.
