Overview This study establishes a critical risk-mitigation protocol for reservoir characterisation in core-poor drilling campaigns. By quantifying the inherent limitations of using borehole images (BHI) alone, the research demonstrates that ...
How can artificial intelligence support high-resolution geological interpretation in one of the Middle East’s most prolific and complex deltaic reservoirs? This study delivers a detailed characterisation of the Lower Cretaceous Zubair Formation across the ...
This R&D initiative enhances an existing Random Forest–based workflow for predicting sedimentological genetic elements in uncored wells by integrating Large Language Models (LLMs). The multi-agent Retrieval-Augmented Generation (RAG) framework addresses the limitation ...

For a holistic characterisation of fine-grained unconventional reservoirs, our integrated approach utilises coherent, reproducible datasets and refined work practices carried out within a comprehensive quality management system. A typical reservoir characterisation includes integration of sedimentological, ...
