Abstract


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.

Author Keywords: Band, Principal component analysis, Band ratio, lineament.


Abstract: (french)


La zone d’étude étant traversée par les méridiens et les parallèles, la proposition des découpages en blocs pétroliers s’est faite sans études géoscientifiques préalables et les blocs pétroliers ne sont rien d’autres que des degrés carrés. Mais les traitements d’images satellitaires LandSat 8 nous ont permis de repérer les linéaments d’origine probablement tectonique afin de ressortir un bon modèle géologique des formations. L’analyse en composantes principales, les rapports des bandes, leur filtrages ont permis d’extraire les linéaments recherchés, de les valider avec d’autres modèles en l’occurrence les validations basées sur le couplage des différentes cartes, les cartes existantes, les images SRTM et les données de terrain afin de les retenir et s’en servir pour une bonne pré-exploration.

Author Keywords: Bandes, Analyse en Composantes Principales, Rapport des bandes, Rehaussement.
