Abstract
A rock testing system includes a rock sample having organic matter provided on a stand in a testing device and a photothermal laser that emits a selected wavelength corresponding to an absorption peak of the organic matter. Methods for testing the rock sample include irradiating the rock sample with the photothermal laser to selectively heat the organic matter and monitoring porosity of the rock sample as the organic matter is heated.
