Conceptual model of geomechanical facies in the Barra Velha Formation, northeastern Búzios Field, Brazil

Orthographic view of the 3D conceptual model depicting the spatial distribution of geomechanical facies within the Barra Velha Formation in the northeastern sector of the Búzios Field. The model, displayed with a 5× vertical exaggeration, highlights the relationship between GMFs and carbonate rock types (grain-size variability and evidence of subaerial exposure), as well as the main structural domains comprising shallow, slope, and bottom settings. The variation in Unconfined Compressive Strength (UCS) across the facies is indicated, illustrating its correlation with lake depth.
