Environmental Risks of Drilling the Brazilian Equatorial Margin
With the 11th round of tendering for O&G block in Brazil set to start next week, it is important to look at some of the serious risks involved in drilling for O&G in Brazil’s Equatorial Margin. Most of the offshore blocks being tendered in this 11th round of bidding are located along Brazil’s northeast and north coasts. This, according to the Brazilian government, is being done in order to de-centralize O&G production in Brazil, where most of the oil and gas E&P is done along the southeast coast, basically centered off the states of São Paulo, Rio de Janeiro and Espirito Santo. This is all well and good, when considering the need to redistribute O&G wealth to other parts of the country…
Offshore Port for Pre-salt Oil in 2012
Petrobras has decided on a novel way to transfer pre-salt oil to export and local market tankers from a maritime operations base. The projects named “Unidade Offshore de Transferência e Exportação” (UOTE) or Offshore Transfer and Export Unit (OTEU), will work as a floating port terminal. Due to the distance from land of pre-salt plays such as Tupi, which is nearly 300km from the nearest coast. The national operator chose to use an DP enabled FSO anchored in shallow waters, 80 to 90km from the coast Rio, in around 70 meters of water to receive and store production oil from shuttle tankers loaded at the production FPSOs, over the pre-salt plays. The FSO will have a capacity to store 2 million barrels of oil and will be connected to underwater pipelines.
Maritime Infrastructure Projects Targeting Brazil O&G Market
As Petrobras announces that it will go through with five more deepwater pre-salt drilling projects this year, totaling 16 pre-salt wells drilled in 2010, a number which will probably increase in 2011 and more pre-salt, deepwater and shallow water plays keep being uncovered, new shipyard and new port projects are getting underway to make up the some of the infrastructure deficit in Brazil.OSX has finally defined that its shipyard will be build next to the Açu Port and Industrial Complex in the northeast coast of the state of Rio de Janeiro. The final decision was decision was based on the competitive advantages of UCN Açu, as attested by the results of comprehensive engineering…
Two Discoveries in One Well Raise Potential for the Campos Basin Pre-salt
The two new discoveries in one well, announced by Petrobras last Thursday, strengthen the thesis pertaining to the possibility of the existence of a great reservoir beneath the salt layer of the Campos Basin. The Campos Basin pre-salt shows its potential even if volumes are less than at the Santos Basin, as various factors related to logistics, production timeline and development costs make this possibility very attractive to players and specially to Petrobras. As is widely known, the Campos Basin is presently responsible for over 80% of the Brazilian O&G production. The discoveries indicate the existence of hydrocarbons in both the pre-salt and the post-salt layers in a single well at the Barracuda field in the Campos Basin, 100km from the coast of Rio de Janeiro.
