SYSTEMS AND METHODS FOR ESTIMATION OF INTRA-KEROGEN POROSITY OF DOWNHOLE FORMATION SAMPLES FROM PYROLYSIS TESTS AND BASIN MODELING DATA

摘要

A method for determining kerogen porosity of a formation for downhole operations, comprises: obtaining pyrolysis data from a plurality of wellbores disposed in a formation; determining a time-temperature burial history of the formation; calculating a kerogen porosity at each of the plurality of wellbores based, at least in part, on the corresponding pyrolysis data and the time-temperature burial history of the formation; generating a kerogen porosity map of the formation based on the calculated kerogen porosity values; and using the kerogen porosity map, determining a new kerogen porosity value for a wellbore without available pyrolysis data.
