Abstract: A policy-driven network traffic manager recommends to individual application programs that generate network traffic whether, and optionally under what conditions, they should generate network traffic. The network traffic manager has an interface, through which the application programs, prior to generating network traffic, call the network traffic manager and describe the traffic the application programs propose to generate. A policy repository stores a set of policies, which the network traffic manager uses to ascertain whether the application programs should generate the proposed network traffic. The policies can include considerations such as time, link cost, latency, congestion and availability. The network traffic manager then sends the recommendations to the application programs.

Abstract: The invention is a method of recovering hydrocarbons from underground hydrcarbon formations by injecting a mixture of carbon dioxide and a polar alcohol or polar glycol additive, said additive having less than about 9 carbon atoms. The mixture of carbon dioxide and additive is injected at a temperature and pressure above the critical temperature and pressure of carbon dioxide. The alcohol or glycol additive comprises about 0.1% to about 10% by weight of the injected mixture. After being injected through an injection well, the mixture is driven through the formation and the hydrocarbons and other fluids are recovered at one or more production wells.

Abstract: The disclosed invention is a group of steam foaming agents for injection with steam and a non-condensable gas to decrease permeability in steam swept zones and increase oil recovery. The foaming agents have the general formula:RO(R'O).sub.n R"CO.sub.2 Mwhere R is an alkyl radical, branched or linear, having from about 8 to about 24 carbon atoms in the alkyl chain, R' is ethylene, propylene or a mixture of ethylene and propylene, n has an average value of about 3 to about 11, R" is methylene or ethylene, and M is an alkali metal or ammonium ion.

Abstract: The disclosed invention is a method of injecting steam foaming agents in conjunction with steam and usually, a non-condensable gas into production wells producing a substantially high water to oil ratio. The most preferred production wells for foaming agent injection are corner production wells of flooding patterns such as inverted 5- and 9-spots, especially when the flooding pattern contains infill wells between the central injection well and the corner production wells.Although the method of injecting foaming agent, steam and usually, a non-condensable gas is effective with any foaming agent, the method works particularly well with foaming agents of the general formula:RO(R'O).sub.n R"SO.sub.

Abstract: The disclosed invention is a group of steam foaming agents for injection with steam and a non-condensable gas to decrease permeability in steam swept zones and increase oil recovery. The foaming agents have the general formula:RO(R'O).sub.n R"SO.sub.3 Mwhere R is an alkyl radical, branched or linear, or an alkylbenzene, alkyltoluene or alkylxylene group, having from about 8 to about 24 carbon atoms in the alkyl chain, R' is ethyl, propyl or a mixture of ethyl and propyl, n has an average value of about 1 to about 20, R" is ethyl, propyl, hydroxypropyl or butyl and M is an alkali metal or ammonium ion.

Abstract: The disclosed invention is a group of novel steam foaming agents for injection with steam to decrease permeability in steam sept zones. They are effective without the coinjection on a non-condensable gas.The foaming agents have the general formula:RO(R'O).sub.n R"SO.sub.3 Mwhere R is an alkyl radical, branched or linear, having from about 15 to about 21 carbon atoms in the alkyl chain, R' is ethyl or propyl, n has an average value of about 2 to about 5, R" is ethyl, propyl, hydroxypropyl or butyl and M is an alkali metal or ammonium ion.
