Abstract: Modern carbonate environments have been respected as natural laboratories to extract dimensional data about carbonate sediment distribution patterns, which can help geologists better explain carbonate sedimentary distribution and is critical to oil exploration and development. With the rapid development of remote sensing technology, the observation technology based on imaging spectral theory has also become mature in recent years. This paper introduces the readers to the mapping technology, which is based on the satellite multi-spectrum data through non-supervised classification and sedimentary data calibration and analysis for mapping sedimentary facies, and its practical application, taking the Great and Little Bahama Banks as examples. The facies maps provide a tool for geoscientists to make global comparisons and analyses so as to improve predictive capabilities in hydrocarbon exploration and production.
