Abstract: FIELD: oil industry.  
     SUBSTANCE: invention relates to the oil industry, in particular to steam-thermal methods for the production of high-viscosity oil and natural bitumen. The method includes drilling a horizontal production well near the bottom of the formation, drilling a horizontal injection well above a horizontal production well parallel to it in a vertical plane at a minimum distance from the roof of the formation, pumping steam into the injection well and taking liquid from the production well. To create a hydrodynamic connection between the producing and injection wells, steam-cyclic well treatments are carried out. When steam is injected into the upper well, liquid is taken from the lower well, and when liquid is taken from the upper well, steam is injected into the lower well, the moment of establishing a hydrodynamic connection between the injection and production wells is fixed, and steam is continuously pumped into the upper injection well and products are taken from the lower production well until the end of the period of production of the displacement element.  
     EFFECT: oil production increases, the amount of produced water decreases, the steam-oil ratio decreases during the development of deposits, the rate of production of deposits increases.

Abstract: Residue-free production of ethanol and unicellular protein in a gas-fluidized bed, in which ethanol production takes place in a gas-fluidized bed (stirred fluidized bed, fluid column), the particle fraction of which consists of a wet microorganism mass, e.g. Saccharomyces cerevisiae. A nutrient solution with fermentable carbohydrates is sprayed onto the fluidized particles. The ethanol, which evaporates with the water, is precipitated in a condenser on the discharge side, so that the fluidized bed serves as bio-reactor as well as one-stage distillation plant (together with the cooling system). Thus, the mash column, which is normally used for alcohol production with the submersion method, is not needed in the present invention. In place of the residue, a protein-rich product with 30-40% dry mass is formed, which, during continuous operation, can be removed at certain intervals from the bioreactor and can be dried to the desired degree. The propagation of the microorganisms can be regulated through the oxygen content of the gas phase; the ethanol production can be regulated through the infeed of the nutrient solution. The gas used for fluidization is recirculated into the bed. The partial oxygen pressure can be controlled by adding other gases to the air, such as nitrogen or carbon dioxide, particularly carbon dioxide, which forms the yeast itself.
