A survey of the airborne hyperspectral images was performed in the Guarumen Exploratory Area, Sub Basin of Guarico in Venezuela, over 4000 Km2. The survey specifications were 3 meters spatial resolution (GSD) with the ProSpecTIR-VS sensor (VINIR-SWIR), 356 spectral bands and a spectra resolution of 5nm. The aim of this project consisted of determining the possible ones associated with hydrocarbon emanations. The hypothesis was based on the hydrocarbon microleakage model (Dietmar Schumacher 1996). The decision by PDVSA Exploration Management to use hyperspectral images was based on the primary function to detect anomalies in minerals and vegetation that are associated with hydrocarbon migrations on the surface, seeking greater exploratory reliability and obtaining a better understanding of the oil system in the study area.
Once with the laboratory results, the hydrocarbon -related hyperspectral anomaly data were integrated with surface geology, geomorphology, analysis of geochemistry, soil and vegetation laboratories to identify the areas with more significant potential for hydrocarbon exploration.
This technique has an advantage in planning seismic and geochemical surveys in detail, managing to precisely direct and focus the location of oil systems at a low cost and a low probability of success. This approach helps to minimize financial risk in acquiring 2D and 3D seismic surveys.
The conventional or traditional way of conducting hydrocarbon exploration through the use of 2D, 3D and Geochemical seismic survey technology is well known, however, every day the costs of these technologies increase, which is why many state and private oil companies currently resort to state-of-the-art techniques that minimize costs. That is why remote sensing technology has specialized in oil and gas exploration processes on the surface, since it allows planning and detection in these surveys, managing to precisely direct and focus the location of the oil systems.
