System and methods for estimation of intra-kerogen porosity of downhole formation samples from pyrolysis tests and basin modeling data

Systems and methods for determining kerogen porosity of a formation for downhole operations are described herein. An example method may include obtaining core pyrolysis data from a wellbore disposed in a formation. A thermal characteristic of the formation proximate to the wellbore, such as a time-t...

More Information
Summary:Systems and methods for determining kerogen porosity of a formation for downhole operations are described herein. An example method may include obtaining core pyrolysis data from a wellbore disposed in a formation. A thermal characteristic of the formation proximate to the wellbore, such as a time-temperature burial history of the formation, may also be determined. A kerogen porosity of the formation may be calculated based, at least in part, on the pyrolysis data and the thermal characteristic, and a downhole operation may be performed based, at least in part, on the calculated kerogen porosity.
