Abstract: An embodiment of a method for unsupervised analysis of borehole image data is provided in which a borehole image is divided into a plurality of image patches, and missing or degraded measurements within at least a portion of the image patches are reconstructed. The method further provides for generating feature embeddings for the reconstructed image patches and processing to enable grouping of image patches that exhibit similar geological texture characteristics. The resulting group assignments are then mapped back to depth-indexed intervals of the borehole image, thereby producing an automated representation of recurring geological textures without requiring labeled training data.
