Sumario:	Compositional determination of crude oil as well as its API degrees are extremely important for its identification and subsequent processing. Currently, this information is obtained using laborious laboratory techniques, which require time and complex experimental infrastructure. In this study, we determined the presence of elements found in crudes extracted from different fields using the LIBS technique, and we present a method to quickly determine crude's quality based on the relationship between API degrees and the CN line's intensity, the later determined by LIBS. Tanto la determinación composicional del petróleo crudo como el grado API son extremadamente importante para la identificación y ulterior procesamiento. Actualmente, esa información es obtenida utilizando técnicas de laboratorio laboriosas, que requieren tiempo e infraestructura experimental costosa. En este estudio, se determina la presencia de elementos en crudos obtenidos en diferentes regiones, aplicando la técnica LIBS, y se presenta un método para evaluar la calidad del crudo, basada en la relación entre el grado API y la intensidad relativa de la línea CN.
