Abstract: A system for acquiring a marine seismic survey makes use of a propelled vessel (40) towing at least a seismic source assembly (100) behind it. The navigation control system (42) of the propelled vessel is instructed to steer the propelled vessel in response to position information repetitively generated by a source global positioning system (GPS, 130) which forms part of the seismic source assembly being towed. The position information from the source GPS is thus used to navigate the seismic source assembly to a target location. The position information from the source GPS is also used to trigger activation of the seismic source when the seismic source is located within a pre-determined distance from the target location.

Abstract: Implementations of the disclosed subject matter provide a method for producing glycols from an anhydrosugar feed. The method may include contacting, in a reactor under hydrogenolysis conditions, the anhydrosugar feed with a bi-functional catalyst system. The bi-functional catalyst system may include a retro-Aldol catalyst and a hydrogenation catalyst. A product stream may be obtained from the first reactor including ethylene glycol and propylene glycol.

Abstract: A hydroprocessing catalyst composition that comprises a chelant treated metal containing support material having incorporated therein a polar additive. The catalyst composition is prepared by incorporating at least one metal component into a support material followed by treating the metal incorporated support with a chelating agent and thereafter incorporating a polar additive into the chelant treated composition.

Abstract: The present invention is a method to determine where fractures are created within a wellbore during a formation fracturing operation, the method comprising the steps of: providing at least one sensor within a carrier capable of measuring and recording a pressure difference across the carrier as a function of time; releasing the sensor into fracturing fluids; injecting fracturing fluids into a wellbore during a fracturing operation; after at least one fracture has formed, permitting fluids to flow back from the fractured formation into the wellbore and to a surface facility; capturing at least one sensor from the fluids which flowed back from the fractured formation; reading recorded data from the captured sensor; and determining the relative size of at least two different fractures based on the recorded data.

Abstract: Processes for producing ethylene carbonate and/or ethylene glycol, and associated reaction systems are similarly provided. Specifically, a process is provided that comprises supplying an overhead absorber stream withdrawn from an absorber to a vapor-liquid separator to yield an aqueous bottoms stream and a recycle gas stream; supplying an aqueous process stream comprising one or more impurities to a distillation apparatus to yield an overhead impurities stream and a purified aqueous process stream; supplying at least a portion of the purified aqueous process stream and an ethylene oxide product stream to the absorber; and contacting the ethylene oxide product stream with the purified aqueous process stream in the absorber in the presence of one or more carboxylation and hydrolysis catalysts to yield a fat absorbent stream comprising ethylene carbonate and/or ethylene glycol.

Abstract: A discrete fracture network model is upscaled to a simulation grid having effective permeabilities for each grid cell. Prior to computing the effective permeabilities, the grid cells are grouped in distinct grid cell clusters, such that flow via fractures is only possible between grid cells that mutually belong to the same grid cell cluster. This is achieved by grouping fractures into distinctive fracture clusters, whereby all fractures that are physically connected with each other by intersection, either directly or indirectly via a number of other physically connected fractures, exclusively belong to one fracture cluster. Each grid cell is assigned to exclusively one fracture cluster. After defining the grid cell clusters, effective permeabilities are calculated for each grid cell using only the fractures of the fracture cluster to which the grid cell is assigned while fractures from other fracture clusters are ignored. Inter-cluster flow impediment data is assigned to selected grid cells.

Abstract: An integrated process for making high molecular weight hydrocarbons from a synthesis gas feed to a Fischer-Tropsch unit. A carbon monoxide resistant gold-on-palladium membrane system (membrane system) is used to control the hydrogen-to-carbon monoxide molar ratio of a feed to the Fischer-Tropsch unit. The membrane system is operatively connected between a steam reformer and the Fischer-Tropsch unit. The membrane system receives a synthesis gas stream and provides for the removal of hydrogen from the synthesis gas stream to provide a retentate stream having a desired H2/CO molar ratio that is fed to the Fischer-Tropsch unit.
