Fluoroscopy is one of the methods of observation that gives primary information about reservoir content, by exposing the sample to ultraviolet light, the hydrocarbon inside the rock sample reflects light in deferent colors, the interpretation of reflecting area ratio and its color define which type of hydrocarbon embedded and its amount, lighter color means lighter type of hydrocarbon, darker color means heavier hydrocarbon.
The core sample in the photo expose blue stains that means this reservoir has a gas bearing.
Note: there is also indirect method of inspection includes a chemical reaction then observing the filtrate.
