摘要： A closed loop system for increasing yield, reducing post process pollution, reducing energy consumed during and after extraction of fuels or contaminants in formations and for sequestering of carbon dioxide C02 from various sources is converted to a critical fluid for use as a flushing and cooling medium. Electrical energy heats a hydrocarbon rich formation resulting in the extraction of hot fluids which are fed to heat exchangers, gas/liquid separator, and steam turbine whereby oil, electric power, carbon dioxide and methane are produced for reuse in the system or for external use. Further, a method for sequestering of carbon dioxide in a formation comprises the steps of injecting CO2 into the reservoir, flushing with cool pressurized CO2 for heat removal, infiltrating with ultra-fine low density suspended catalyst particles of dry sodium hydroxide in CO2, pumping water moistened CO2 into the reservoir to activate the catalysts, binding the CO2 with reacting materials and capping the reservoir.

摘要： Increased foam quality and resistance to hydrocarbon defoaming for foams used in well boring and stimulation processes as well as secondary and tertiary oil recovery is obtained using imidazoline-based amphoacetates of higher purity, containing essentially negligible amounts of unalkylated amido amines, lower amounts of glycolic acid salts and monochloroacetate salts.The higher purity amphoacetates can be obtained via processes utilizing precise pH control during the reaction of imidazoline, or its open-chain derivatives, with alkylating agents, e.g. sodium monochloroacetate. These higher-purity amphoacetates contain essentially fully alkylated products and lower amounts of glycolic acid derivatives, even though a ratio of monohaloalkylate to substituted imidazoline, or its open-ring derivative, of less than 1.5:1.0 and close to 1.0:1.0 is used.

摘要： The invention is a foam method for improving conformance during a steam flood or carbon dioxide flood in a subterranean, oil-containing formation penetrated by at least one injection well and at least one production well. In a steam flood oil recovery process, sweep efficiency is improved by injecting steam until steam breakthrough occurs at the production well after which a mixture of steam, a noncondensible gas, and an aqueous surfactant-polypeptide solution is injected into the formation. The aqueous surfactant-polypeptide solution forms a stable foam with the formation oil at formation conditions that reduce the permeability of the highly permeable steam swept zones thereby diverting the steam to other portions of the formation containing unswept oil. The polypeptide is used as a partial substitute for the surfactant to improve the cost of the foam-forming mixture without reducing its effectiveness in increasing sweep efficiency. In another embodiment of the invention, the mixture of steam, surfactant-polypeptide solution and noncondensible gas may be injected into the formation surrounding a production well that has previously experienced severe steam breakthrough to significantly decrease the permeability of steam-swept zone surrounding the production well.
摘要翻译：本发明是一种用于在由至少一个注入井和至少一个生产井穿透的地下含油地层中的蒸汽洪水或二氧化碳洪水期间改善一致性的泡沫方法。在蒸汽泛油回收过程中，通过注入蒸汽来提高吹扫效率，直到在生产井发生蒸汽渗透，然后将蒸汽，不可冷凝气体和表面活性剂 - 多水溶液的混合物注入到地层中。水性表面活性剂 - 多肽溶液在形成条件下形成稳定的泡沫，其中地层油降低了高渗透性蒸汽扫过区的渗透性，从而将蒸汽转移到含有未除油的地层的其它部分。多肽用作表面活性剂的部分替代物以改善泡沫形成混合物的成本，而不降低其提高扫描效率的有效性。在本发明的另一个实施方案中，可以将蒸汽，表面活性剂 - 多肽溶液和不可冷凝气体的混合物注入到先前经历过严重蒸汽渗透的生产井周围的地层中，以显着降低围绕生产井的蒸汽扫过区的渗透性。
