Abstract :

The amount of Total Organic Carbon (TOC) is one of the most important parameter in evaluating hydrocarbon source rocks. Therefore, it is necessary to estimate of source rock by a method. There are several methods for estimating the of source rocks. One of the earliest methods is the traditional method, which is very expensive and time consuming, so researchers are looking for more efficient methods. Given the high potential of remote sensing and spectral VIR spectra, the VNIR makes it possible to estimate the characteristics of the origin rock at a lower cost basis. Different quantitative and qualitative methods are used to establish a relationship between the concentration of rock elements and the spectrum obtained from remote sensing data. In this study, we tried to estimate the total organic carbon content of the total origin rock using the OLI Landsat 8 image sensor and using the MLP artificial neural network model. For this purpose, the band of 5 spectral ranges (0.845-0.8585) with Pearson correlation coefficient of 0.62 was chosen for the neural network. An artificial neural network with neurons in the secret layer with R2 = 0.79 and RMSE = 0.0008 were selected to generate a total organic carbon map.
