FIELD: development of deposits.
SUBSTANCE: group of inventions relates to the development of deposits of hard-to-recover hydrocarbon reserves. The composition for intensifying the production of hard-to-recover hydrocarbon reserves contains a transition metal tallate selected from the group: iron Fe, nickel Ni, cobalt Co, copper Cu, tungsten Wo, molybdenum Mo, manganese Mn, aluminium Al, zinc Zn, chromium Cr; donor-hydrogen organic solvent; nonionic, or ionic, or amphoteric surfactant in the following ratio, wt.%: tallate 1-45; solvent 45-98; surfactant 1-10. Tallate contains, wt.%: ligand based on distilled tall oil 88.4-93.8; transition metal 6.2-11.6, and the distilled tall oil includes, wt.%: monobasic unsaturated fatty acids 50-65; resin acids 30-40; unsaponifiable substances - the rest.
EFFECT: enhanced oil recovery due to in-situ upgrading and reduced viscosity and density of high-viscosity, super-viscous, bituminous oils and natural bitumens.
