Action Continues at the Santos Basin Deepwater Pre-Salt

June 21, 2013

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.

Petrobras Shows Its Strength

With Brazilian presidential elections imminent, and having just completed its successful shares offer, Petrobras finds itself in a privileged position with the new pre-salt legislation guaranteeing the company as sole operator of all the pre-salt blocks negotiated from the 11th bidding round onwards.Although some parts of the new legislation are still to be voted it is considered as a certainty that the bils concerning Petrobras´ greater influence in the pre-salt will pass. Since the discovery of the Tupi field in 2007, and other pre-salt fields discovered at the Santos Basin, there has been national and global excitement over the possible extent of Brazil´s pre-salt reserves.

FPSO Cidade de Angra dos Reis Beginning Production at the Tupi Field

The MODEC owned and operated FPSO Cidade de Angra dos Reis MV22 has been moored in 2,150 meters (7,053 ft) at its final operational location over the giant Tupi area in the Santos Basin. O&G production operations will begin in a few weeks after on-location tests.MODEC converted the VLCC "M/V Sunrise IV" into an FPSO at the COSCO (Dalian) Shipyard Co., Ltd. (“COSCO Dalian”) in China. The FPSO is classified by ABS as 29.7 meters in depth, 58.00 meters in breadth, and 318.46 meters in length. The conversion from VLCC to FPSO involved steel fabrication, module installation and integration, the installation of cables, pipe and equipment.

Tupi Commercial Production Start-Up to be Anticipated

Petrobras is likely to anticipate by 2 or 3 months commercial O&G production at the Tupi pre-salt field.The initial schedule for commercial O&G production at the Tupi pre-salt field held December 31 2010 as the maximum deadline for start-up. The revised schedule calls for commercial production start-up to begin in September or October 2010, anticipating the production by 3 months. This will make it possible for the government to have 2 pre-salt fields in commercial production before the presidential elections, scheduled for November 2010. Commercial production at Tupi is expected to be around 100 million barrels per day (bpd), from 5 production wells to be connected to the BW offshore FPSO Cidade de Angra, currently being adapted at a shipyard in China.

Brazilian Pre-Salt Frontiers to Expand

July 22, 2010

According to major Brazilian O&G market sources, the official Brazilian pre-salt area boundaries will have to be expanded due to various pre-salt discoveries beyond presently acknowledged frontiers.Companies such as Petrobras, Repsol, Anadarko and Shell have made important pre-salt discoveries away from the Picanha Azul area where the Tupi field is located and where all the blocks drilled presented commercial hydrocarbon accumulations. Repsol is making history in Brazil with block ES-T-737, where they are drilling to a goal depth of 7,500m (24,606ft). Repsol is hedging on finding oil under the salt layer in an area beyond officially recognized pre-salt boundaries.

Unique Corus Tubes for Tupi Project

July 9, 2010

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.

Aker Solutions do Brasil Ltda. was recently awarded a large subsea contract by Petrobras to supply subsea trees for two of Brazil's pre-salt areas. With this latest contract and the previous contract for subsea trees at the Tupi field, Aker Solutions has secured its presence in all the pre-salt fields presently being developed by Petrobras.Aker Solutions do Brasil Ltda. has signed a frame agreement with Petrobras to supply 40 subsea trees for the Iara and Guará fields, located in the challenging pre-salt area of the Santos basin offshore Brazil. The contract is of approximately USD 300 million. The scope of works includes engineering and manufacturing of 40 vertical subsea trees for 2.500 meter water depths, subsea control systems and 17 complete tool sets.

New Well Confirms Tupi´s Potential Recoverable Oil Reserves

New discovery at the Tupi field confirms Tupi potential and another new discovery in an ANP block, to be included in onerous concession contract with Petrobras.In early April 2010 Petrobras Petróleo Brasileiro S.A. announced that it finalized the drilling of another well in the Tupi field which confirms the potential of the pre-salt reservoirs in that field. The new well, 3-BRSA-795-RJS (3-RJS-666), and informally known as Tupi OW, is located in the area of the Tupi Evaluation Plan, at a depth of 2,131 meters, nearly 270 km of the coast of Rio de Janeiro, and 12.5 km northeast of the discovery well, 1-RJS-628 (1-BRSA-369), known as Tupi.

New Pre-salt Discovery has 4,5 billion barrels of Recoverable Light Oil

This new ANP discovery is the 2nd largest pre-salt discovery to date in Brazil and highlights the excellent potential of the Brazilian pre-salt.The ultra deepwater well (2-ANP-1-RJS ) was drilled at an area which has been named Franco, it lies 2.189 meters deep and the 4,5 billion barrels of light oil are of around 30º API. The well is located 195km from Rio de Janeiro and 41 km from the Iara pre-salt field, which has a recoverable oil potential of 3 to 4 billion barrels. Both are located at the Santos Basin. The Tupi field, also at the Santos Basin is still the largest discovery to date in Brazil, will a recoverable oil potential of 5 to 8 billion barrels.
