摘要： To assist electric submersible pumps in producing highly viscous crudes from oil wells, injection water is conveyed to the pump assembly, injected into the crude, and mixed with it to form an oil-in-water emulsion. This effectively decreases the viscosity of the produced fluid and helps to control pump operating temperatures. The water injection is done in a shroud at the base of the submersible pump.

摘要： A process is provided in which carbon dioxide is injected into an oil-containing reservoir as an aid in recovering oil from the reservoir. Oil can be produced from at least one production well in the reservoir and carbon dioxide-containing hydrocarbon gas will be produced with the oil. Heavy ends are stripped from the carbon dioxide-containing hydrocarbon gas and substantially all of the carbon dioxide in reinjected into the oil-containing reservoir.

摘要： This invention relates to a method of producing supercritical carbon dioxide from a well along with minor amounts of kill water having formation salts dissolved therein. The salt water is the result of killing the well with fresh water during pump installation and/or removal operations at which time the water enters the CO.sub.2 producing formation and dissolves soluble salts which come into the well when the kill water returns to the well when it is put on production. Precipitation of salts carried by the kill water in the pump is prevented by continuously injecting water into the vicinity of the pump intake so as to dilute the returning kill water before it, or at least a portion of it, is vaporized into the water phase of the supercritical carbon dioxide. The volume of injected, substantially fresh water must be sufficient to handle the vaporization of water into the carbon dioxide in the pump as well as dilute the returning kill water so that the salts carried thereby remain in solution.

摘要： A packing assembly which is connectable to reeled tubing and which can be inserted in and pushed through a wellbore tube by the reeled tubing. The packing assembly is hydraulically set in a locking and sealing position in the wellbore by fluid introduced from the reeled tubing and, after use, is hydraulically released and removed from the wellbore. An actuating apparatus is provided for hydraulically actuating the packing assembly and can be converted in a manner to pull the packing assembly from the wellbore. Prior to the removal of the packing assembly from the wellbore, the wellbore fluid pressure is equalized across the packing assembly.

摘要： A method and system for flue gas recirculation is disclosed which will minimize NOx production from hydrocarbon combustion. In the present invention a furnace having an oxygen-bearing primary source of combustion air, a mixing chamber, a combustion chamber in downstream communication with the mixing chamber and an exhaust section downstream of the combustion chamber is provided with a flue gas recirculation line. The recirculation line establishes communication between the exhaust section and the mixing chamber for the return of combustion products as a secondary source of combustion air which is relatively lean in oxygen and is combined with the primary source of combustion air in the mixing chamber. The ratio of flow rates for the primary and secondary sources of combustion air is controlled by a signal generated by a sensor which senses the oxygen concentration in the mixing chamber.

摘要： A fireproof boom for containing flammable pollutants on water includes a flotation member and at least two layers of heat-resistant, water-sorbent material surrounding the flotation member. The flotation member is a series of cylindrical metal cans held end-to-end by the heat-resistant material. The heat-resistant, water-sorbent material draws water around the heat-sensitive flotation member, forming steam in the presence of flaming pollutant and allowing only the outer layer of heat-resistant material to become slightly singed.
