Geochemistry of shale is a valuable tool for oil and gas exploration. In this study laser induced breakdown spectroscopy (LIBS) was used for elemental analysis of shale rock obtained from Bakken formation in the United States. LIBS is a rapid analytical technique that can provide elemental information of every element in the Periodic Table of a given sample. Analysis of H and C can be useful in obtaining information on the gas generation potential of a shale. The technique can also be used for elemental mapping, which is useful in determining mineral phases and chemical zonation within a mineral. The shale samples were analyzed using a 266 nm Nd:YAG nanosecond pulse duration laser and a grid pattern that covered 8 mm X 8 mm area. The data collected were used to construct 2D elemental maps and efforts were made to quantify elements of interest. This study shows that the LIBS can provide a rapid analysis of shale samples.
