This data release is a compilation of vitrinite reflectance (Ro) data from the Southwestern Wyoming Province in Wyoming, Colorado, and Utah. The data includes about 1,200 Ro measurements from...
-
The most commonly used parameter for thermal maturity calibration in basin modelling is mean random vitrinite reflectance (Ro). However, Ro suppression, or lower than expected Ro, has been noted...

Chemostratigraphic signatures were recorded in a 113 m thick outcrop of late Albian to early Campanian (~103–82 Ma) Hue Shale exposed on the bank of the Jago River in the coastal plain (“1002...

Conventional methods of assessing organic matter (OM) thermal maturity have limitations and often fail to reflect the geochemical heterogeneity between individual organic phases in mudstone...
-
For sample mounting, organic petrology laboratories typically use cold-setting epoxy-resin (e.g., 40°C, used by Oklahoma Geological Survey, OGS) or heat-setting plastic (e.g., 180°C, used by U.S....

Mean random vitrinite reflectance (Ro) is the most widely accepted method to determine thermal maturity of coal and other sedimentary rocks. However, oil-immersion Ro of polished rock or kerogen...

National Assessment of Oil and Gas Project - Southwestern Wyoming Province (037) Maturation Contours
The maturation contours show vitrinite reflectance trends and ranges for petroleum system horizons within the Southwestern Wyoming Province. The horizons are the base of the Niobrara Formation,...

The maturation contours show vitrinite reflectance trends and ranges for five key petroleum system horizons within the Uinta-Piceance Province. The horizons are the lower part of the Green River...
-
To test if reflectance increases to sedimentary organic matter (vitrinite) caused by broad ion beam (BIB) milling were related to molecular aromatization and condensation, we used Raman and...

This data release contains geochemical and petrographic data for the Eagle Ford Group in the USGS Gulf Coast #3 (GC-3) core and the Mowry Shale and Frontier Formation in the Nerd Gas Co. Oil...
-
The molecular composition of petroliferous organic matter and its composition evolution throughout thermal advance are key to understanding and insight into petroleum generation. This information...

The U.S. Geological Survey assessed undiscovered petroleum resources in the downdip Paleogene formations of the U.S. Gulf Coast in 2018. During the assessment new data and information were...
-
This study evaluated carbonaceous shales proximal to coal measures and coal samples via isothermal hydrous pyrolysis (HP) to compare differences in the maturation pathways of vitrinite in...

This work investigates the characterization of bituminite (amorphous sedimentary organic matter) in Kimmeridge Clay source rock via confocal laser canning microscopy (CLSM) and atomic force...
-
The thermal maturity grids are results generated from the petroleum systems model for five major source rock intervals, which include, from youngest to oldest, the Tyler, Mission Canyon, upper...
