Aptian carbonate rocks of Santos Basin in the Brazilian southeastern continental margin
show a highly heterogeneous reservoir quality conditioned by many controlling factors. This …

Flow units (FUs) have been widely used for rock typing in many reservoirs, especially where
there is no direct correlation between petrophysical properties and geological …

Planar structures including stylolites, solution seams, dense streaks, bedding and cross-
bedding surfaces, and fractures of carbonate Early Triassic Kangan Formation were …

In this study, based on stereographic projections, two sets of planar structures were
identified in the Mozduran reservoir, a prolific reservoir in Northeast Iran. The first set …

The Pre-salt strata are idealized as a lake-dominated breakup depositional sequence
recorded between the South American and African continental margins to which there is no …

Presalt lacustrine carbonate rocks forming highly productive Santos Basin discoveries below
Aptian evaporites are described and interpreted here. Based on rock calibration to well logs …

Residual oil saturation (Sor) is a petrophysical parameter of great relevance, as it is used for
flow simulation, production forecast, and reserve estimation. However, oil trapping is rarely …

Abstract The Barra Velha Formation encompasses the most important hydrocarbon
reservoirs of the Pre-salt section of the Santos Basin, SE Brazil, and its lacustrine carbonates …

Digital petrophysics investigates the properties of rocks from images, especially core
computed tomography (CT scan). The purpose of these investigations is to develop new …

Activities related to the offshore exploration and production of oil and natural gas provide
economic development and an essential energy source. However, besides the risk of …
