Abstract
A method, comprising receiving input data representing a subterranean formation, defining a grid representing the input data, with the grid including cells. The method also includes identifying at least one of the cells in which kerogen is present based on the input data, simulating hydrocarbon movement within the kerogen using the grid, and generating a model of hydrocarbon expulsion to pore space based on the simulating.

A method, comprising:
- receiving input data representing a subterranean formation;
- defining a grid representing the input data, wherein the grid comprises cells;
- identifying at least one of the cells in which kerogen is present based on the input data;
- simulating hydrocarbon movement within the kerogen using the grid;
- and
- generating a model of hydrocarbon expulsion to pore space based on the simulating.
A computing system comprising:
- one or more processors;
- and
- a memory system comprising one or more non-transitory computer-readable media storing instructions that, when executed by at least one of the one or more processors, cause the computing system to perform operations, the operations comprising:
- receiving input data representing a subterranean formation;
- defining a grid representing the input data, wherein the grid comprises cells;
- identifying at least one of the cells in which kerogen is present based on the input data;
- simulating hydrocarbon movement within the kerogen using the grid;
- and
- generating a model of hydrocarbon expulsion to pore space based on the simulating.
