October 10, 2014

banner fmi
As a world leader in construction and remote operations in deep waters, Petrobras has been developing new technologies and testing them with their partners in Brazil’s deepwater pre-salt fields for over a decade. Petrobras has historically opted for an incremental strategy to develop its technological capabilities to explore the Brazil’s offshore oil resources. As deepwater discoveries began to enter the production phase, Petrobras opted for using and FPSOs and wet x-mas trees. These discoveries of supergiant oil fields in the Brazilian pre-salt have offered Petrobras an opportunity for reviewing its technological path and it is becoming clear that the national operator has been increasingly inclined to move as much of the oil production systems to the seafloor as possible…

The system will connect Luanda in Angola, with Fortaleza in Ceará in northern Brazil and the u/w cable with have a capacity to transmit 40 terabits per second, or 40 trillion bits per second, which will greatly speed up trans-Atlantic media, O&G and general business connections. Eventually an extension of the cable will also reach Santos, on the coast of São Paulo and Miami. The initial project will have an investment of US$160 million, with another US$100 million destined to extra connections. This is the essence of the South Atlantic Cable System (SACS), which cable operator Angola Cables plans to install by 2015 or the beginning of 2016 in the region. According to company president Antonio Nunes, this will be the first u/w cable in the southern hemisphere linking Brazil to Africa.

January 23, 2014

Carcara map
The Carcará oilfield off the Brazilian coast is named for a bird of prey that is liberally known as the Brazilian Eagle, its scientic name is: Polyborus Plancus. Carcará located in Block BM-S-8 is believed to hold one of the thickest reservoirs ever discovered in Brazil's Santos Basin pre-salt cluster, with a reservoir thickness of 471 meters. The play is being developed by a consortium composed of Petrobras (66%), Galp Energy (14%), and Brazilian players QGEP and Barra Energia with (10%) each. Tested flow rates and reservoir conditions at the Carcará discovery are superior to the famous Lula field. The Lula field, which is currently producing about 100,000 bopd, is estimated to hold recoverable reserves of between 5 billion and 8 billion boe.

A Monster Named Libra

June 18, 2013

Libra 1
Back in 2009 I asked a good friend of my late father, who happened to be a long time Petrobras geologist, if he really knew the full potential of the pre-salt, after a while he looked up and said no not really, I know there are big fields out there, probably up to 10 billion boe in some reservoirs, possibly much more... Well, Petrobras kept on drilling and when Libra was found northeast of the Lula field (5 to 8 billion barrels boe), in 2010, the expectations ran high. Maybe 3.7 billion boe, maybe 15 billion boe. Probably 7.9, those are the numbers the ANP had in 2010. By May 2011 the ANP was downgrading it to 5 billion barrels boe.

Shallow Water Pre-salt Discovery to Spark More Driiling

June 18, 2013

2005
The recente Discovery of a shallow water pre-salt reservoir by Brazilian private operator OGX has definitely raised a few eye brows. This novelty is a first in Brazil as up to now all other pre-salt reservoirs have been found in ultradeep waters off the Brazilian coast and usually very far from the coast. This new discovery which is located in BM-S-57 Block, in the Santos Basin and is less than half the distance from the mainland as other pre-salt finds in the Santos Basin, exactly 102 km from the coast of Rio de Janeiro. The wellhead is only 155 meters deep and the well was drilled down to 6,135 meters, which is the normal depth where pre-salt reservoirs are expected to be found.

Laje Viva Institute - Divers take a stand

June 16, 2013

The Laje Viva Institute was born from the indignation of a group of divers towards illegal fishing that, unfortunately, is a reality in the Laje de Santos Marine State Park. Divers spotted fishing vessels at the park and became indignant and irate with this practice, leading them to take action. From this point on, a few divers decided to meet and start to take action having a clear objective: "Protect Laje de Santos from fishing and hunting". On July 1st, 1993, these divers founded the Laje Viva Institute, a non-profit organization with the objective of implementing actions to guarantee the preservation and protection of the Laje de Santos Marine State Park (PEMLS).

Even as Petrobras allegedly slows its exploration efforts, new discoveries are still being uncorked in the Santos Basin. While the national player announced the start up of the EWT in the Guará area in late December, yesterday a new deepwater pre-salt light oil accumulation is discovered in an adjacent area at the same BM-S-9 exploratory block. The Guara  EWT is producing through well SPS-55, and  is expected to last for five months with a daily production is estimated at 14,000 barrels of oil per day. The Guará area is located in block BM-S-9 and around 300 kilometers off the coast of São Paulo state. The recoverable O&G volumes in Guará are estimated at between 1.1 and 2 billion boe with a around 30º API.

After a nearly perfect drilling campaign on various fronts in 2010, OGX start 2011 with new discoveries in the Campos Basin. Although there was much skepticism at the start of OGX´s creation in 2007, after last year´s performance, the new Brazilian operator, which was created by Brazilian businessman and investor Eike Batista adding to the portfolio of his EBX Group can now easily be considered as a good investment, especially for those who bought in early. Eike´s strategy to hire and partner with Petrobras´s extraordinary geologist and executive Paulo Mendonça was vital not only to gain market value as to bring in deep knowledge of where do drill and how to plan the E&P campaign. It´s important to not that Petrobras´s exploratory success rate more than doubled after Mr.

Petrobras Considering New Strategy for Driller Orders

November 29, 2010

petrobrasconsideringnewstrategyfordrillerorders
Using its Norwegian branch to launch a drillship operator is one of the options that Petrobras is evaluating in order to administer the 28 drillships the company plans to order.This option would entail creating a holding company as a subsidiary to Petrobras Netherlands B.V. (PNBV) to administer the operation of the 28 drillers to be ordered in the coming years in order to fulfill the drilling needs of the company´s aggressive exploratory campaign in looking for major reservoirs along the Santos Basin pre-salt. The main reason for using a PNBV subsidiary would be to speed up the company´s creation so as not to affect the planned exploratory schedule and also to decrease the company´s direct investment.

chinesetryingtobuystakesofanogxplayatthesantosbasin
China Petrochemical (Sinopec) and the Chinese national oil company (CNOOC) are holding separate negotiations with OGX Petroleo e Gás in order to acquire 20% of an OGX deepwater play at the Santos Basin. In general we can see a marked increase in Chinese involvement and investments in Brazil.These negotiations are the most recent effort of Chinese oil companies in Latin America. Normally Chinese oil investments are driven to Asia, the Middle East and Africa, regions that historically concentrate the majority of Chinese imports in energy sources and raw material. As recently as May of this year, Sinochem Group, China’s biggest chemicals trader, agreed yesterday to pay $3 billion to Statoil ASA for 40 percent of the Brazilian offshore Peregrino field.

Unique Corus Tubes for Tupi Project

July 9, 2010

uniquecorustubesfortupiproject
Corus Tubes manufactured the thickest UOE 18” ever made especially for deepwater pipes at the Tupi field, in the Santos Basin.Corus Tubes has successfully manufactured 118km of 457mm x 31.75mm Grade X65 sour linepipe for the Petrobras Tupi project. This linepipe is designed to operate in Brazil’s Santos Basin at a depth of 2200m, and is thickest 18” UOE pipe manufactured to date. The design criteria allowed for fatigue and corrosion concerns as well as depth/collapse issues, and this led to the demanding and previously untried thickness to diameter ratio (t/D) of 0.0695. Some innovative steps were taken by Corus Tubes to control pipe shape, a critical element for subsequent laying of the pipe and collapse performance.
