A proposal for the structure and organization of a drilling database and a knowledge base, is described. Previous studies formed the principal elements in the process of selection of drills for proposed drilling. The procedure was implemented as a computer system for the selection of tricone bits. A drilling bit database for three different Brazilian sedimentary basins was obtained for several wells drilled, and knowledge was collected from drilling engineers from different fields both electronically and also by means of interviews. It can be concluded that the selection process showed good results based on tests, which were carried out.15-22spaDrill bit selectionIntelligent systemKnowledge baseOil well drillingDatabase systemsSedimentary rocksIntelligent systemsKnowledge based systemsArtigoAcesso restrito2-s2.0-0042429103
