Abstract: A measured wetness of and a carbon isotope ratio associated with a gas sample from a hydrocarbon formation is received wherein the wetness is a percentage of C2+ by mass. The carbon isotope ratio is a ratio of carbon-13 isotopes over carbon-12 isotopes. Calculated wetnesses of and carbon isotope ratios associated with a plurality of gas samples taken from one or more analogous hydrocarbon reservoirs is received. Each wetness is calculated as a percentage of mass within the gas sample. The measured wetness received for the gas sample from among the calculated wetnesses is identified. A carbon isotope ratio is determined from among the carbon isotope ratios that corresponds to the measured wetness of the gas sample. A gas maturity for the gas sample is determined using the determined carbon isotope ratio.

The first rotating arm has first and second ends and the second rotating arm includes third and fourth ends. The first and third ends are rotatably fixed to the bottom plate. The fourth end defines a sliding groove into which the second end is slidably fixed. When the second end rotates around the first end toward the bottom plate, the second end slides along the sliding groove and the third end rotates toward the bottom plate. An elastic member is between the first rotating arm and the bottom plate and when the first rotating arm rotates, the elastic member abuts against the bottom plate to drive the first printed board to move toward the second printed board.

Abstract: Carbonate samples are received from a wellbore formed in a geologic formation. An oxygen isotope ratio and carbon isotope ratio present within each of the carbonate samples are determined. A mineral composition of each of the carbonate samples is determined. A plot showing the determined oxygen isotope ratios versus a depth from where within the wellbore each of the carbonate samples was obtained is created. One or more negative oxygen isotope shifts are identified based on the plot. Natural carbonate cement levels within one or more of the plurality of carbonate samples that correspond to the one or more negative oxygen isotope shifts identified in the plot are determined. One or more production sweet spots are determined based on the identified negative oxygen isotope shifts and the determined natural carbonate cement levels.

Abstract: A core sample with carbonate veins is obtained from a well formed in the hydrocarbon reservoir. Formation water samples are obtained from the well. Mineralogy of carbonate in the carbonate veins is analyzed. An oxygen isotope ratio between oxygen isotopes in the formation water and an oxygen isotope ratio between oxygen isotopes in the carbonates are determined. A formation paleo-temperature value is determined based on the determined oxygen isotope ratio using a model that relates the formation paleo-temperature value and the oxygen isotope ratio.
