VetcoGray´s Metal-to-Metal Sealing Technology
The increase in exploratory O&G programs around the world and specifically the deepwater exploration programs being undertaken at the GOM, in West Africa and Brazil has caused major improvements and new technologies and materials to be employed in subsea equipment, such as BOPs, wellhead systems, risers, manifolds, flowlines, drilling fluids among others. GE´s VetcoGray has developed an interesting seal technology for its subsea wellheads. Named MS seal, it is based on Metal-to-metal sealing technology. All VetcoGray subsea wellheads use metal-to-metal sealing technology, which is superior to elastomer options because it prevents inevitable heat and corrosive fluids from damaging seal integrity. Both the wellhead and hanger have a sealing area of parallel wickers.
Coastal Monitoring, Preservation and Research Investments in Brazil
As huge investments are made in Brazil to develop the country`s O&G potential, actions targeting preservation of coastal and underwater ecosystems along the Brazilian coast are still lacking. With the Brazilian coast being 7,491 km long, it is even understandable that the Brazilian government, Petrobras and environmental agencies, find it difficult to expand coastal preservation projects to include the whole coast including the thousands of coastal islands. Petrobras has been making important investments in preservation of coastal and underwater ecosystem along the Brazilian coast, sponsoring far reaching projects in various areas, such as preservation of coastal flora and fauna, fisheries management and environmental education programs for coastal communities.
Subsea Processing Systems Expanding in Brazil
The advent of reliable subsea processing has taken a considerable time to develop. For a few years now, it has been looked at as a vital solution for deepwater O&G development. Subsea processing technology was first developed to overcome challenges posed by extremely deep wells but in time it has become a proven solution in mature fields by decreasing the amount of equipment on the surface, therefore lowering operational costs and of course by boost diminishing production from mature wells, normally through re-injection of fluids, such as water, into the wells to increase the pressure inside the well. It is also an important solution in locations where harsh surface weather conditions make it extremely risky to have an anchored production plant.
Petrobras Betting on Partnerships to Develop Deepwater Equipment and Solutions
Due to the extreme demands placed on subsea equipment used in the pre-salt E&P Petrobras has been forming various partnerships with local and foreign companies to develop specially designed equipment to tackle the hazards of deepwater pre-salt development. One of the newest partnerships implemented by Petrobras, was for a feasibility study on Flexible pipes for practical oil production in pre-salt area with Japan Oil, Gas and Metals National Corporation (JOGMEC). JOGMEC and PETROBRAS have a long history of research and development partnerships which started back in 2005, for collaboration on mutual benefit O&G exploration and production activities, HSE related matters, and R&D activities of the O&G sector.

New Deepwater Discoveries in Brazil
Petrobras, Brazil´s National operator hás recently disclosed new local and international O&G discoveries. The discoveries in Brazil are all in deepwater. In the Espírito Santo Basin the hydrocarbon accumulations were found in the Cretaceous reservoirs of a well known as Brigadeiro, down at 1,900 meters and located within the BM-ES-23 concession area in Block ES-M-525, 115 km off the coast of the State of Espírito Santo in southeast Brazil. This new deepwaterdiscovery at the very promising Espirito Santo Basin, was confirmed through wireline logging and fluid sampling, in t reservoirs located at around 4,200 meters.Petrobras is the operator of block BM-ES-23 (65%), which is also composed of Shell Brasil Petróleo (20%) and Inpex Petróleo Santos (15%).
Synthetic DYNEEMA Ropes for Deepwater MODU
With the increase in deepwater O&G exploration, the demand placed on mooring ropes for MODUs (Mobile Operating Drilling Units) has increased dramatically. Rope manufacturers have been developing products based on new materials and also adapting their manufacturing processes to accommodate new materials and more stringent requirements. In some deepwater plays mooring ropes will be going down to 2,000 or even 3,000 meters, which places massive stress on the ropes, due not only to its length and weight but also due to the action of subsea currents, ship movement caused by surface waves, currents and wind. Dutch rope manufacturer Lankhorst Ropes…

Ultra-Deepwater AUVs and ROVs show their value by finding AF 447s Fuselage
If the earlier searches for the debris had made a more intensive use of ultra-deepwater AUVs, finding the sunken fuselage, the black boxes and voice recorders may have taken considerably less than two years. However we must also consider that the total estimated search area was huge. The first idea of using submarines, just wasn´t enough with the extreme depth involved (3,900 meters). France had announced last February that it would begin the 4 phase of its search for the AF 447 debris, somewhere over 700 km from the north coast of Brazil, beyond the remote islands of Saint Peter and Saint Paul, a notorious shipwreck location. The new effort aimed to find the downed Airbus A330-200, which crashed on May 31 2009, killing all 228 passenger and crew members as it flew from Rio to Paris.

Rising Environmental Concerns greet the Woods Hole Group in Brazil
The Woods Hole Group (WHG), headquartered in East Falmouth, Cape Cod, Massachusetts, recently announced the launching of its first office in Brazil over increasing concerns about possible environmental problems which may be triggered by the continued increase in O&G exploration in Brazil. There are no local environmental organizations in Brazil that can match the experience, expertise and credibility of the WHG in terms of providing comprehensive solutions to challenges and consequences of environmental problems. Although Brazil´s official environmental impact agency “IBAMA” is undoubtedly experienced and even efficient in its environmental impact monitoring, it is still a government agency and therefore it can hardly be considered completely independent.
The Toucan and the Dragon
It took a while to happen, but Petrobras and Chinese oil and petrochemical companies finally reached partnership agreements. Considering the scope of the Brazilian pre-salt and the expected growth of the Brazilian O&G market, these partnerships may become vital, as much more investments will be needed along the next 10 years. These partnerships in research and O&G exploration and production have been in negotiations for a long time but it took an official Brazilian delegation, headed by Brazilian President Dilma Rouseff, going to China, in order make it happen. It was a certainty in the market that this partnership would eventually come to be, it was just a matter of when it would happen and what it would encompass.
Deepwater Umbilical Challenges in Brazil and Worldwide
In the past all umbilicals were made of thermoplastics, used mainly for transport of hydraulic fluids to open or close valves, with separate hoses connecting to each valve on a subsea tree. As the deepwater production increased, concerns over possible failures on thermoplastic umbilicals mounted, triggering the development of the steel tube umbilical. Efficiency and reliability are the keys for deepwater umbilicals. The modern subsea umbilical used by the O&G industry provides transmission of electric and fiber optic signals, electrical power, hydraulic fluids, and injection of chemical fluids from the surface to the seabed through electric and/or fiber optic cables encased in thermoplastic and/or steel tubes.
