Oil blocks have been delimited by parallels and meridians squares since years up to now in DRC. This technics is not suitable and common, that is why in order to better limit the different oil blocks in the West-Congolian sedimentary basin, we used the Lansat 8 data to bring out lineaments which help to set geological structural model. Lineaments probably coming from tectonic movements have been identified throughout the surface of lithological units in the West-Congolian basin. The principal component analysis, the band ratio and some filterings helped to get more details about that. Data coming from existing maps combined with groundtruth data have been compared to teleanalytic data.
