... reconciling scalar differences between measurements and depth control divergence during acquisition poses a challenge. Current depth matching methodologies, often manual and based on naturally occurring radioactivity measurements may not have a high applicability for pre-salt carbonate rocks, where...

... ABSTRACT Carbonate rocks are responsible for a considerable amount of hydrocarbon reservoirs worldwide. In Brazil, a huge part of petroleum reserves is associated with carbonatic facies formed during Aptian and Albian times, specially on offshore basins of east coast. These sedimentary...

... poses challenges due to the vertical and lateral variations in petrophysical properties. These properties are governed by rock fabric or spatial arrangement of grains and pores. In carbonates, rock fabric is affected by several factors including postdepositional processes, interplay of diagenesis...
