Abstract: The present disclosure generally relates to the utilization of a fine mineral matter in the process of upgrading the liquid products obtained by thermolysis or pyrolysis of solid plastic waste or biomass or from cracking, coking or visbreaking of petroleum feedstocks. More particularly, the present disclosure is directed to a process of stabilization of the free-radical intermediates formed during thermal or catalytic cracking of hydrocarbon feedstocks including plastic waste and on a process of catalytic in-situ heavy oil upgrading. The fine mineral matter may be derived from natural sources or from synthetic sources.

Abstract: Provided are a system and method for actively recovering thermal energy, hydrocarbons, and other energy resources from a formation. In one example, multiple fluid conduits are inserted into a borehole. Combustion fluid is injected into the formation via one of the conduits. The combustion fluid is used to ignite and maintain a combustion zone by burning fuel in the formation. To extract thermal energy, cool fluid is circulated through the borehole via another conduit and heated by the thermal energy in the combustion zone. Thermal energy may be recovered from the heated fluid or other processing may be performed for various types of energy recovery. A fluid flow and composition of the combustion fluid and a fluid flow rate of the cool fluid may be individually controlled for purposes such as regulating heat transfer, balancing thermal energy recovery with enhanced oil recovery (EOR), and regulating temperature and pressure for safety.

Abstract: A heavy oil thermal recovery method based on staged injection of a supercritical multielement thermal fluid, comprising: extracting light crude oil in response to detecting that the oil storage stratum having an ignition temperature through preheating the oil storage stratum; increasing a temperature of the oil storage stratum through igniting heavy oil in the oil storage stratum having the ignition temperature; and injecting, sequence to heating the oil storage stratum to a required temperature, a multielement thermal fluid into the oil storage stratum, and extracting crude oil sequence to an operation of closing in. Reaction temperature is increased by heat released by the crude oil during combustion, and a supercritical state of water is reached. The addition of a catalyst can promote the reaction, and therefore, when the temperature drops below a critical point in partial regions, the catalyst can ensure the reaction is continuously and efficiently carried out.

Abstract: A carbon dioxide to hydrocarbon conversion device and method are disclosed. A partially produced hydrocarbon subterranean reservoir comprising residual hydrocarbons is provided. A carbon dioxide source is provided, positioned on a surface proximate to the reservoir. A surface mounted high-pressure fluid injector system connecting the carbon dioxide source and the reservoir is provided. A backflow preventer is disposed in-line between the injector system and the reservoir. The injector system injects a catalyst-free feed stream, comprising carbon dioxide, into the reservoir up to an operating pressure. The backflow preventer maintains the operating pressure in the reservoir and sequesters the feed stream in the reservoir. The sequestered carbon dioxide reacts with water and at least a portion of the residual hydrocarbons over a time period to produce additional hydrocarbons. The water is present in the reservoir, provided by the feed stream, or both. The additional hydrocarbons are recovered after the time period.

Abstract: Methods of stimulating subterranean formations are given in which thermite is placed downhole and then ignited. The thermite may be ignited with a downhole tool, the fracture may be mapped, and the thermite-affected region of the formation may be reconnected to the surface after the thermite reaction through the original or a second wellbore.
