PYROLYSIS TO DETERMINE HYDROCARBON EXPULSION EFFICIENCY OF HYDROCARBON SOURCE ROCK

摘要

Some examples of pyrolysis to determine hydrocarbon expulsion efficiency of hydrocarbon source rock can be implemented by performing an open system pyrolysis of a hydrocarbon source rock sample obtained from a natural system. Sample includes hydrocarbon source rocks having an equivalent spherical diameter of substantially at least one centimeter. After the open system pyrolysis, the sample can be crushed and thermally vaporized. A hydrocarbon expulsion efficiency of hydrocarbon source rock in the natural system can be determined based on hydrocarbons recovered in response to the open system pyrolysis and in response to the crushing and thermal vaporization.
