Abstract
Building subsurface models requires the incorporation of geological knowledge that often comes in the form of text. Such knowledge is typically first converted into mathematical formulation and then used as part of an inverse problem as a penalty or constraint. Stable diffusion models can be used for conditional image generation thus digitizing the geological information into spatially varying priors that can later be used in inversion. Here we show how such priors can be generated and conditioned using well logs. In particular, we create a new small dataset where we extract patches from well-known public seismic models. The dataset of less than 50 samples extracted from public geological models and annotated using a large language model with vision capability is sufficient to fine-tune an open-source stable- diffusion pipeline. This approach allows a new way of working with geological descriptions or any other information with minimal effort.
