What is a pre-salt basin?
The pre-salt layer is a diachronous series of geological formations on the continental shelves of extensional basins formed after the break-up of Gondwana, characterised by the deposition of thick layers of evaporites, mostly salt.
Where is Santos Basin?
Brazil
The Santos Basin (Portuguese: Bacia de Santos) is an approximately 352,000 square kilometres (136,000 sq mi) large mostly offshore sedimentary basin. It is located in the south Atlantic Ocean, some 300 kilometres (190 mi) southeast of Santos, Brazil.
What is Brazil basin?
a depression in the bottom of the southern part of the Atlantic Ocean, west of the South Atlantic Ridge. It extends approximately 3,000 km from north to south and is 6,537 m at its deepest point. The ocean bottom is covered with red clay in the east and foraminiferous silts in the west.
What is mero3?
The Mero 3 FPSO is expected to have a processing capacity of 180,000 b/d of oil and 12 MMcm/d of gas. Production is expected to start in 2024. The topsides modules will be designed and manufactured across Asia, with main engineering and execution activities done through Singapore.
What is the major religion in Brazil?
Roman Catholic
Roman Catholic was the most common religion affiliation in Brazil in 2018. In a survey carried out between July and August of 2018, around 58.1 percent of Brazilian respondents claimed to be of catholic faith, whereas the second most chosen religion was Evangelism, with 17.4 percent of the people interviewed.
What do you mean by basin?
A basin is a depression, or dip, in the Earth’s surface. Basins are shaped like bowls, with sides higher than the bottom. They can be oval or circular in shape, similar to a sink or tub you might have in your own bathroom. Some are filled with water.
Which is the main pre salt reservoir in Santos Basin?
The Barra Velha Formation comprises the main pre-salt reservoir in deep-water areas of the Santos Basin. After the main syn-rift stage, a >2 km-thick evaporite succession was deposited in the study area (Ariri Formation; Moreira et al., 2007) (Fig. 4).
Are there any seismic surveys in the Santos Basin?
The next phase for Santos Basin appraisal and development will require new seismic data that captures the pre-salt accurately. Top: Location of the XArray Triple Source project which will cover the Aram, Carcará and Uirapuru areas.
How big are the rocks in the Santos Basin?
The Guaratiba Group is 4,200 metres (13,800 ft) thick and includes four formations, from old to young the Camboriú, Piçarras, Itapema and Barra Velha Formations. The group is equivalent to the Lagoa Feia Group of the Campos Basin. The Camboriú Formation is 40 metres (130 ft) thick and includes the basaltic rocks with a basin–wide distribution.
How is pre-salt topography related to reservoir erosion?
An incomplete correlation between pre-salt topography, top reservoir erosion, and salt deformation in deep-water Santos Basin (SE Brazil) Salt deformation in deep-water SE Brazil was long lived. Folds and thrusts do not necessarily occur above pre-salt structures. Increased deformation in distal areas is associated with ridge-push phenomena.
