    摘要: The present invention provides stationary CT architecture for imaging at a faster temporal resolution and lower radiation dose. In embodiments, the architecture features stationary distributed x-ray sources and rotating x-ray detectors. Provided is a stationary source computed tomography (CT) architecture comprising: a detector disposed on a rotatable gantry; an x-ray source disposed on a fixed ring; wherein the detector is disposed on the gantry in a manner such that the detector is capable of rotating around a subject and of receiving a signal from the x-ray source. Embodiments of the invention include a CT-MRI scanner comprising the stationary CT architecture.

    摘要: A method of recovering crude oil from a subterranean hydrocarbon containing formation which comprises (a) injecting into said formation an aqueous solution containing an effective amount alkali metal, alkaline-earth or ammonium salts of alcohol ether sulfonates derived from unsaturated alcohol ethers, and (b) displacing said solution into one or more injection wells and recovering the oil from one or more production wells. The unsaturated alkoxylated alcohol contain various amounts of ethylene oxide, propylene oxide and butylene oxides elected to optimize their interfacial properties with different types of crude oil with different brines.

    摘要: The present invention discloses a process for producing polyalkylated arylalkyl sulfonic acids by reacting arylalkyl sulfonic acids with olefins. The polyalkylated arylalkyl sulfonic acids may be further neutralized with alkalis or amines to form the corresponding sulfonated salts. The present invention also makes possible manufacture of polyalkylated arylalkyl sulfonic acids as first intent products using an inexpensive and simple reaction. The structure of the polyalkylated arylalkyl sulfonic acids produced using the process described in the present invention is shown below: Where R1, R2 and R3 are each separately and independently H, alkyl (branched or linear C1 to C30), (—CH2CH2O)a, (—CH(CH3)CH2O)b, or (—CH2CH2O)c(—CH2(CH3)CH2O)d, m+n=8 to 28 R4=CH2CH3, CH2CH3Y or Y(CH2)pCH(CH2)qY p+q=0 to 27 a=1 to 30 b=1 to 30 c+d=2 to 30 Y=CH3, COOH, CH2OH, CH2(—CH2CH2O)a, CH2(—CH(CH3)CH2O)b, CH2(—CH2CH2O)c(—CH2(CH3)CH2O)d, aromatic, or substituted aromatic.

    摘要: A process for recovering heavy oil with the steps of: a) injecting into one or more injection wells an aqueous injection fluid containing one or more surfactants designed to form a pseudo-emulsion between the injection fluid and the heavy oil, and, b) recovering the oil from one or more producing wells. The process does not require the addition of outside mechanical or thermal energy or solvents to recover the heavy oil and does not form emulsions between the injection fluid and the heavy oil that may be difficult to break when brought to the surface or may cause increased viscosity and injectivity problems within the reservoir.
