  • Patent number: 9146225
    Abstract: A method for detecting hydrocarbons with an underwater vehicle equipped with one or more measurement components is described. The method includes navigating the UV within the body of water; monitoring the body of water with measurement components associated with the UV to collect measurement data. The collected data from the UV is used to determine whether hydrocarbons are present and at the location.

  • Publication number: 20150167588
    Abstract: Catalyst compositions suitable for use in the exhaust gas recycle stream of an internal combustion engine are provided. Such catalyst compositions typically provide significant amounts of methane in addition to syngas. A reformer incorporating such a catalyst for use in an exhaust gas recycle portion of an internal combustion engine powertrain is described. A powertrain incorporating such a reformer, a method of increasing the octane rating of an exhaust gas recycle stream, and and a method of operating an internal combustion engine using methane-assisted combustion are also described.

  • Publication number: 20150127313
    Abstract: A method of determining a presence and location of a subsurface hydrocarbon accumulation from a sample of naturally occurring substance. An expected concentration of isotopologues of a hydrocarbon species is determined. An expected temperature dependence of isotopologues present in the sample is modeled using high-level ab initio calculations. A clumped isotopic signature of the isotopologues present in the sample is measured. The clumped isotopic signature is compared with the expected concentration of isotopologues. Using the comparison, it is determined whether hydrocarbons present in the sample originate directly from a source rock or whether the hydrocarbons present in the sample have escaped from a subsurface accumulation. The current equilibrium storage temperature of the hydrocarbon species in the subsurface accumulation prior to escape to the surface is determined. A location of the subsurface accumulation is determined.

  • Publication number: 20150119542
    Abstract: An electrochemical conversion method for converting at least a portion of a first mixture comprising hydrocarbon to C2+ unsaturates by repeatedly applying an electric potential difference, V(?1), to a first electrode of an electrochemical cell during a first time interval ?1; and reducing the electric potential difference, V(?1), to a second electric potential difference, V(?2), for a second time interval ?2, wherein ?2??1. The method is beneficial, among other things, for reducing coke formation in the electrochemical production of C2+ unsaturates in an electrochemical cell. Accordingly, a method of reducing coke formation in the electrochemical conversion of such mixtures and a method for electrochemically converting carbon to C2+ unsaturates as well as an apparatus for such methods are also provided.

  • Publication number: 20140303895
    Abstract: A method is disclosed for determining for determining a presence, type, quality and/or volume of a subsurface hydrocarbon accumulation from a sample related thereto. The method may include determining a noble gas signature of a sample and at least one or more of determining a clumped isotope signature of the sample and characterizing the ecology signature of the sample. Then, the method integrates signatures to determine information about the subsurface accumulation, such as the location, fluid type and quality, and volume of a subsurface hydrocarbon accumulation.

  • Publication number: 20140288853
    Abstract: A method is disclosed for determining a presence, type, quality and/or volume of a subsurface hydrocarbon accumulation from a sample related thereto. The method may include obtaining sample data associated with a subsurface hydrocarbon accumulation, wherein the sample data includes a noble gas signature, a clumped isotope signature and/or a ecology signature. From the signatures, relationships between the noble gas signature; the clumped isotope signature and the ecology signature are identified and stored in memory.

  • Publication number: 20140256055
    Abstract: A method for detecting hydrocarbons is described. The method includes performing a remote sensing survey of a survey location to identify a target location. Then, an underwater vehicle (UV) is deployed into a body of water and directed to the target location. The UV collects measurement data within the body of water at the target location, which is then analyzed to determine whether hydrocarbons are present at the target location.
