ABSTRACT:
A method of preparing a thin section sample includes affixing the sample to a receptacle using an affixing media that includes a material having a thickness-sensitive characteristic. The sample may then be shaped to have an asymmetric cross-section. The method may further include reducing a thickness of the material until the thickness-sensitive material exhibits a change in an optical characteristic. The added material, which may be quartz, may exhibit a predetermined optical characteristic at a specified thickness and/or exhibit a change in an optical characteristic in response to a change in thickness. In one application, the method may include retrieving the sample from a subterranean formation. For instance, the sample may be retrieved from a gas shale formation.
