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.
Petrobras Introduces Oil-Water Separator at the OTC 2010
The Petrobras oil-water subsea separator pilot project includes the qualification test, design and construction of a prototype to be installed in the Marlim Field, at the Campos Basin.During the OTC 2010 in Houston, Petrobras unveiled its subsea oil-water separation, which is being developed by FMC Technologies. This system will push the limits of the subsea three-phase separation envelope to deep waters and heavy oil. Petrobras and FMC are performing an extensive qualification test program for the key components of the separation unit. The increasing produced water rate, its respective treatment costs and limited processing capacity at the existing platforms are the main drivers for Petrobras to move towards a subsea three-phase separation and reinjection system.

Sevan Driller – New One of a Kind Deepwater Driller in Brazil
The Sevan Driller is a one of a kind deepwater and harsh environment driller which has arrived in Brazil and is preparing to start operations for Petrobras in the Campos Basin.Sevan Marine has developed a cylinder shaped floater, suitable for all offshore environments, using their own proprietary technology. Presently, Sevan Marine has four FPSO contracts, including the Goliat Sevan 1000 FPSO, and three drilling contracts with clients. One of their cylindrical FPSOs, the Sevan Piranema is already in operations in Brazil for Petrobras on an 11 year fixed contract with 6 x 1 year options + 5 x 1 year mutually agreed . The FPSO Sevan Piranema has performed with consistently high production uptime levels since its start up in October 2007.
The World´s First All-Electric Intelligent Completion System – Back to the Future
The all-electric intelligent completion system has evolved for deep and ultra deepwater. When the world's first all-electric intelligent completion was installed in a subsea deepwater well in the Campos Basin, it was the culmination of five years of development, testing and trials. System acceptance was mild, but with the improvements that have been made and the vital role this system will have in ultra deepwater plays, its future looks very bright.On Aug. 3, 2003, the world's first subsea, deepwater, all-electric intelligent completion system was installed in the 8-MLS-67HA-RJS well, in 3,540 ft (1,180 m) of water at Marlim Sul field. The well is about 60 miles (100 km) offshore at the Campos basin, Rio de Janeiro, Brazil.
Anchoring Flowlines, FPSOs and Rigs in Deepwater – The Torpedo Pile
Among the many challenges facing E&P in the Brazilian deepwater pre-salt plays, is that of anchoring the flowlines, platforms, FPSOs and even buoys to the seabed which can be over 2000 meters deep. Petrobras has developed a simple and efficient method of doing this through the Torpedo Pile.In the case of the deepwater pre-salt plays in Brazil, specially at the Santos Basin, the distance from land to some of the proven plays like Tupi and Iara, which are around 300km from shore and pose complex logistics problems even on surface structures. Challenges, such as how to anchor a deepwater rig or FPSO to the seabed 2,200 meters down must be resolved. It is a long distance for anchors to travel, normally four or more anchors are used and these anchors need to be aligned.
Deepwater Challenges in Brazil
From seismic data analysis to intelligent wells, the challenges facing deep water O&G production in Brazil are being faced.Just five years ago, many of the technologies we now take for granted in subsea systems development, would have been considered improbable, at best. Although, these same technologies have been under development by players and specially by the major subsea systems providers for a decade and in many cases quite a bit longer than that. There is no doubt in the subsea industry that most deepwater subsea system experiments started in the North Sea and some old deepwater projects in the GOM, with few early projects being conducted in the very peculiar Brazilian Deep.
The OGX Exploratory Campaign Maintains Its High Success Rate
OGX Petróleo e Gás Participações S.A., the largest Brazilian private sector oil and gas company in terms of offshore exploratory acreage, announced today that it has completed the drilling of well 1-OGX-5-RJS, located in block BM-C-43, in the shallow waters of the southern part of the Campos Basin. OGX holds a 100% working interest in this block. The well OGX-5 was drilled to a depth of 4,100 meters, resulting in the detection of hydrocarbons in carbonate reservoirs in the Albian and Aptian sections. Cable tests performed after the conclusion of drilling also identified an oil-bearing column in the Maastrichtian section, from which oil samples were collected.

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.
