Identificação de fácies em perfis com algoritmo heurístico

Abstract

The development of oil well drilling techniques and the optimization exploitation of various hydrocarbon reservoirs on the same time, an issue has drawn attention from researchers from the oil industry: identification of sedimentary facies in wells not core available. Therefore, this paper proposes the use of a heuristic algorithm based on the behavior of insects, which contributes to the interpretation of M-N Graphic on computational way. Using wells logs and plot your data in graphic M-N, we have aimed to sort of well log points in relation to fixed points, using the creation of groups (clusters) of data that have some similarity or symmetry, based on what we call attractiveness. Using the creation of these groups of points of the well log, in the neighborhood of fixed points through which suffered major attraction, we can do the identification of multiple data families which, in this work, will be taken as layers, depending on which mineral fixed point are closer, can have their main mineral composition identified without the help of the core and thus obtain the sedimentary facies knowledge overpassed by the well.
