The method includes obtaining a thermal maturity relationship and the source sample from a geological region of interest. The method further includes separating aromatic fraction from the source sample, and separating, measuring, and identifying responses of the aromatic fraction using gas chromatography-mass spectrometry (GC-MS) and determining a thermal maturity ratio using the responses. The method still further includes determining a thermal maturity indicator using the thermal maturity ratio and the thermal maturity relationship and determining the hydrocarbon type based on the thermal maturity indicator. The system includes a ball mill, a pipette column, a GC-MS system, and a computer processor.

Abstract: Compositions, devices, and methods relating to the use of mixed-matrix membranes containing metal-organic frameworks to separate gases are generally described. In some embodiments, branched nanoparticles made at least in part of metal-organic frameworks are described. In some embodiments, the morphology and size of the branched nanoparticles are controlled by the presence of a chemical modulator during synthesis. In some embodiments, the branched nanoparticles are uniformly distributed in a mixed-matrix membrane. In some embodiments, the mixed-matrix membrane is configured to separate one or more gases from a gas mixture. In some embodiments, the branched nanoparticles contribute at least in part to an increase in permeability, selectivity, and/or resistance to plasticization of the mixed-matrix membrane.

Abstract: A system includes a housing configured to be secured to the casing string. The housing has a ring shape defining a central orifice for passage of the fluid and an interior surface facing the central orifice. A reflectometer is mounted on the interior surface and is configured to emit a microwave signal into the fluid in the central orifice, receive a reflected microwave signal from the central orifice, and determine a microwave reflection parameter. An acoustic transceiver is also mounted on the interior surface and is configured to emit an acoustic signal into the fluid in the central orifice, receive a reflected acoustic signal from the central orifice, and determine an acoustic reflection parameter. A processor is configured to determine the property of the fluid from the microwave reflection parameter and the acoustic reflection parameter.
