Consumption of petroleum products continues to grow steadily. In 2020, oil consumption numbers surpassed exploration's, indicating a possible market imbalance. That said, the demand for new oil reserves becomes essential. Prospecting techniques for these commodities are used to have greater accuracy before drilling a well. Different Geological, Geophysical, and Geochemical methods are applied with different principles in their search, with Seismic being the most widely used technique. Sniffers have gained ground among geochemical methods, and new technologies are emerging. Despite many methods, none is conclusive and should be used in conjunction with others, whether in the prospecting area or for leak monitoring.
