Annotation:

The research is based on thermovision tomography of the Earth's Crust by processing the Landsat-8 spectral-zonal satellite image in the thermal infrared wavelength range (8…14 microns) with a spatial pixel resolution of up to 60 meters. Models of the thermodynamic field at the time of the survey were built - sections and maps of the thermal field and block-fault structures for the given depths with reference in geographic coordinates. Zoning of the MVIA block for hydrocarbons prospecting was accomplished in the Republic of Cameroon. The endogenous flux of thermal radiation was used to study the geological structure of the medium with the classification of inhomogeneities by shape. On the basis of mapping faults and rocks with improved reservoir properties, zones of fluid flows and accumulations have been established, which can be natural reservoirs of hydrocarbons. Using the TWT method, two types of structural oil traps have been established: near-fault, which was penetrated by a productive well, and the erosion one, located on the ledge of the foundation block within two project wells.
