Title
(EN) METHOD FOR AUTOMATED STRATIGRAPHY INTERPRETATION FROM BOREHOLE IMAGES
(FR) PROCÉDÉ D'INTERPRÉTATION DE STRATIGRAPHIE AUTOMATISÉE À PARTIR D'IMAGES DE TROU DE FORAGE
Abstract
(EN)
Embodiments of the present disclosure are directed towards systems and methods for automated stratigraphy interpretation from borehole images. Embodiments may include constructing, using at least one processor, a training set of synthetic images corresponding to a borehole, wherein the training set includes one or more of synthetic images, real images, and modified images. Embodiments may further include automatically classifying, using the at least one processor, the training set into one or more individual sedimentary geometries using one or machine learning techniques. Embodiments may also include automatically classifying, using the at least one processor, the training set into one or more priors for depositional environments.

Selon des modes de réalisation, la présente invention concerne des systèmes et des procédés d'interprétation de stratigraphie automatisée à partir d'images de trou de forage. Des modes de réalisation peuvent consister à construire, à l'aide d'au moins un processeur, un ensemble d'apprentissage d'images synthétiques correspondant à un trou de forage, l'ensemble d'apprentissage comprenant une ou plusieurs images synthétiques, des images réelles et des images modifiées. Des modes de réalisation peuvent en outre consister à classer de manière automatique, à l'aide du ou des processeurs, l'ensemble d'apprentissage en une ou plusieurs géométries sédimentaires individuelles à l'aide d'une ou de plusieurs techniques d'apprentissage machine. Des modes de réalisation peuvent également consister à classer de manière automatique, à l'aide du ou des processeurs, l'ensemble d'apprentissage en un ou plusieurs précédents pour des environnements de dépôt.
