... and CH4 in the kerogen and clay structures needs quantitative investigation. In this paper, we aim to (a) quantify the effects of kerogen composition, pore structure, and thermal maturity on the CO2:CH4 competitive adsorption behavior, (b) quantify the effects of clay surface chemistry on the CO2 and CH4...

Paper Number: URTEC-3860229-MS
.... It’s important to note that the selected retort temperature regime for Formation X in Basin A may very well be different than Formation Y in Basin B due to variations in source rock (kerogen) type, thermal maturity and/or a number of other factors. Therefore, a tailored experimental set up...

.... The purpose of the basin modeling was to refine the thermal maturity estimates through additional geochemical core and well calibration data. No changes were made to the one-dimensional (1 D) model. Changes to the threedimensional (3 D) model include a modified temperature scaler to better match well...

..., economics, and field thermal maturity patterns. For single source hydrocarbons, thermal maturity is highly correlated to the thermally evolved fluid chemistry eventually produced at the surface. Production measurements such as gas density, oil density, and gas-oil ratio, directly reflect the evolved...

Paper Number: URTEC-3863429-MS
.... When the samples were heated during pyrolysis, water made a difference in the content of Rock-Eval (RE)-derived parameters. During AHP and HP, the analyzed samples changed in terms of thermal maturity, organic matter (OM) quantity and quality, and remaining hydrocarbon generation potential. Unresolved...

... the solid organic matter. As Sh2 increased, the total solids obtained from NMR increased. A trend of increase in the solids vs. thermal maturity was evident, and a correlation between NMR solids and TOC of the Norwood in the three coreholes was observed. Since the Antrim Shale cores had been stored for many...

... as a function of wellbore placement as well as regional geology. Within the context of thermal maturity, our study addresses whether Niobrara oils exhibit unique geochemical signatures stratigraphically among landing zones and regionally across the basin. We use high-resolution gas chromatography (HRGC...

Paper Number: URTEC-3720274-MS
.... Previously we showed using a combination of experimental methods and molecular simulation studies that kerogen type, thermal maturity, and reservoir temperature conditions affect the contact angle of the water droplet on kerogen surface, and therefore, wettability of kerogen. Wettability affects...

... studies have shown that organic pores can have variable wettability depending on the geochemistry of the rock. However, there is no comprehensive study on the impact of kerogen type and thermal maturity on the adsorption of methane. Moreover, methane adsorption is shown to be scientifically affected...
