Due to the increa.ed dema.d for energy resources these da.s, especia.ly due to the Russia.-Ukra.nia. wa., the focus of the ma.or countries is turning strongly towa.ds improving oil production, especia.ly hea.y a.d extra.hea.y oil, which represents 40% of the world oil reserve.

These complica.ions comprise stea. brea.through, stea. overla., a.d stea./rock intera.tions.
