The identification of potassium (K) and magnesium (Mg) salts prior to the well drilling is a
key factor to avoid washouts, closing pipes, fluid loss damage, and borehole collapse. The …

On the account of the absence of modern analogues, the interpretation of evaporite-bearing
basins relies extensively on seismic and well data. Recent studies describe the intrasalt …

The exploration of pre-salt reservoirs in the Santos Basin, Brazilian Offshore, requires
innovative approaches to improve the quality of reservoir seismic images below large salt …

The thick and heterogeneous salt section in the Santos Basin, offshore Brazil, imposes great
challenges in accessing the pre-salt hydrocarbon reservoirs, especially in relation to seismic …

Abstract The Santos Basin is located in the South Atlantic Ocean and is limited in the north
by the Cabo Frio High and in the south by Florianopolis High. It has an area of about 350 …

The pre-salt reservoirs in the Santos Basin are known for being overlaid by thick evaporitic
layers, which degrade the quality of seismic imaging and, hence, impacts reservoir studies …

Correct representation of the spatial distribution of physical and chemical properties of the
evaporitic section is of great importance for development of pre-salt section reservoirs. In the …

This paper presents the benefits of combining geological velocity modelling with Least-
Squares Migration to generate seismic images for the Brazilian presalt reservoirs. The …

Structurally complex areas, such as the pre-salt section in the offshore Santos Basin, SE
Brazil, is a challenge to represent the geology using seismic images. One of the main …

Presalt reservoirs in the Santos Basin are the main O&G accumulations of Brazil. It is
remarkable that the seismic data evolution regarding acquisition and processing, delivers …
