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.

Abstract: A locking structure applied to lock a first housing of a server cabinet to a second housing includes a main body, a control portion, a driving portion, and a hand-held portion. The main body is positioned at the first housing. The control portion is positioned inside the main body. One end of the driving portion is rotatably mounted to the control portion. One end of the hand-held portion is rotatably connected to the main body and other end of the driving portion.

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 measured wetness of and a ?13C associated with a gas sample from a hydrocarbon formation is received wherein the wetness is a percentage of C2+ by mass. Calculated wetnesses of and ?13C values 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 ?13C is determined from among the ?13C values that corresponds to the measured wetness of the gas sample. A gas maturity for the gas sample is determined using the determined ?13C.
