Method for operating a production well in an oxygen driven in-situ combustion oil recovery process

Abstract: A method for operating a production well during an oxygen driven in-situ combustion oil recovery process comprising continuously injecting an inert gas such as nitrogen or carbon dioxide into the bottom of the production well at a predetermined low injection rate, preferably 0.1 to 2 MSCF/day, and continuously monitoring the oxygen concentration of the produced effluent gas and the bottomhole temperature of the production well. In the event that the oxygen content of the effluent gas increases to a value within the range of 5 to 20 volume percent or the bottomhole temperature of the production well increases to a value within the range of 200° to 300° F., the injection rate of the inert gas into the bottom of the production well is increased to a maximum rate until the oxygen concentration of the effluent gas and the bottomhole temperature are reduced to a safe level.

A Low-Tension Waterflooding Process

Abstract: Laboratory and field work using polymer and surfactant slugs for tertiary recovery in watered-out fields led to the conclusion that an oil bank can be formed in a sandstone reservoir using low-tension surfactants. It is essential that the mobility behind the bank be controlled to insure maximum recovery of mobilized oil. The surfactant used in the field tests was a commercial petroleum sulfonate blend with an equivalent weight of about 415. In order to protect the surfactant, an aqueous solution of sodium chloride was injected prior to the surfactant to screen the low-tension sulfonate from the reservoir brine and to base exchange the reservoir solids, replacing magnesium and calcium with sodium ions. Sodium tripolyphosphate or sodium carbonate, or both, is added to the rear portion of the surfactant slug to reduce adsorption and to improve water-wetness of the reservoir rock surfaces. The mobility control slug injected after the surfactant consisted of a water-soluble biopolymer in combination with sodium chloride of concentration less than the minimum that provides very low tension. Field testing was done on a producing sand in the Loma Novia field, Duval County, Texas. Recoveries were not given in terms of barrels per day or percent, although themore » author stated that oil cuts peaked in two wells at 20 percent and 12 percent.« less

Method and system for supplying hydrogen for use in fuel cells

Abstract: The present invention provides a method and system for efficiently producing hydrogen that can be supplied to a fuel cell (52). The method and system of the present invention produces hydrogen in a reforming reactor (12) using a hydrocarbon stream (21) and water vapor stream (25) as reactants. The hydrogen produced is purified in a hydrogen separating membrane (14) to form a retentate stream (42) and purified hydrogen stream (40). The purified hydrogen can then be fed to a fuel cell (52) where electrical energy is produced and a fuel cell exhaust stream (76) containing water vapor and oxygen-depleted air is emitted. In one embodiment of the present invention, a means and method are provided for recycling a portion of the retentate stream (42) to the reforming reactor (12) for increased hydrogen yields. In another embodiment, a combustor (94) is provided for combusting a second portion (48) of the retentate stream (42) to provide heat to the reforming reaction or other reactants. In a preferred embodiment, the combustion is carried out in the presence of at least a portion (92) of the oxygen-depleted air stream (76) from the fuel cell (52). Thus, the system and method of the present invention advantageously uses products generated from the system to enhance the overall efficiency of the system.

Composition of synthetic porous crystalline material, its synthesis

Abstract: This invention relates to a new synthetic composition of ultra-large pore crystalline material, a method for its preparation and use thereof as sorbent and in catalytic conversion of organic compounds. The new crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams anhydrous crystal at 50 torr and 25° C.
