    Abstract: An apparatus for making fast gas chromatography measurements of an oilfield gas includes an infrared laser configured to emit an infrared laser beam; an infrared sensor configured to receive the infrared laser beam; a Fabry-Perot gas cell deployed in a path between the infrared laser and the infrared sensor such that the infrared laser beam passes through the gas cell, the gas cell configured to receive the gas sample; a gas chromatography column assembly including an input port, a gas chromatography column, and an output port, the gas chromatography column assembly configured to provide the gas sample to the Fabry-Perot gas cell; and a controller in electronic communication with the infrared sensor and configured to process the received infrared laser beam to estimate a composition of the gas sample.

    Abstract: A system includes processing circuitry and a non-transitory, computer-readable medium that includes instructions that cause processing circuitry to receive logging data regarding a fluid. The logging data is indicative of a plurality of isotope ratios of a plurality of alkanes of the fluid. The instructions also cause the processing circuitry to determine, based on at least a first isotope ratio of the plurality of isotope ratios of the logging data corresponding to a first alkane of the plurality of alkanes, a thermal maturity of the fluid. Additionally, the instructions cause the processing circuitry to determine, based on at least a second isotope ratio of the plurality of isotope ratios corresponding to a second alkane of the plurality of alkanes, a gas-oil ratio (GOR) of the fluid. Furthermore, the instructions cause the processing circuitry to cause display of the thermal maturity of the fluid and the GOR of the fluid.

    Abstract: Various implementations directed to analyzing a reservoir using fluid analysis are provided. In one implementation, a method may include determining mud gas logging (MGL) data based on drilling mud associated with a wellbore traversing a reservoir of interest. The method may also include determining first downhole fluid analysis (DFA) data based on a first reservoir fluid sample obtained at a first measurement station in the wellbore. The method may further include determining predicted DFA data for the wellbore based on the first DFA data. The method may additionally include determining second DFA data based on a second reservoir fluid sample obtained at a second measurement station in the wellbore. The method may further include analyzing the reservoir based on a comparison of the MGL data and a comparison of the second DFA data to the predicted DFA data.
