Pre-salt Production Start for P-58
Petrobras’s P-58 FPSO started operations at Parque das Baleias, off the state of Espírito Santo, on the north sector of the Campos Basin through well 7-BFR-7-ESS, another pre-salt producer, which is showing an excellent productivity. P-58 is part of the North project of Parque das Baleias, which encompasses production from Baleia Franca, Cachalote, Jubarte, Baleia Azul and Baleia Anã plays. P-58 is moored approximately 85 km off Espírito Santo, at a water depth of 1,400 meters. In the upcoming months, 15 production other wells, being 8 pre-salt and 7 post-salt, as well as 9 injection wells will be interconnected to it through 250 km of flexible pipelines and two subsea manifolds.
O&G reserves in the South China Sea: Tempers Flaring
Geopolitical location, an abundance of fish and huge O&G reservoirs make the South China Sea (SCS) particularly attractive to the countries that all lay claim to parts of it, such as China, Taiwan, the Philippines, Malaysia, Brunei, Vietnam, Indonesia, Singapore, Thailand and Cambodia. While the Chinese National Offshore Oil Company (CNOOC) estimates the SCS holds around 125 billion barrels of oil and 500 trillion cubic feet of natural gas in uncorked reserves, the U.S. Energy Information Administration (EIA) estimates the SCS contains only approximately 11 billion barrels of oil and 190 trillion cubic feet of natural gas in proven and probable reserves, although the EIA admits this figure could increase pending geological surveys of peripheral locations.
Flexible Risers in Deepwater Production – Reliability Concerns
Flexible risers are being extensively used worldwide for deepwater O&G extraction, offering many advantages over rigid risers. However concerns still exist about the overall safety of the system, especially concerning failures leading to hydrocarbon leaks in the ocean environment.The flexible risers being used in deepwater are designed to work for a period of around 20 to 30 years, which is the expected lifetime of an O&G field. A flexible riser failure could happen due to a number of reasons, such as hostile environmental hazards and material fatigue and if the failure is catastrophic, it could lead to high economic and environmental consequences. Flexible risers comprise multiple layers, and the main layers of concerns are the tensile armor layers which exist to withstand tension loads.
Rio Grande Naval Complex - Dedicated to Brazil´s Pre-salt
The launching of the Rio Grande Naval Complex completes another key project for pre-salt production, as the complex will house the hybrid pre-salt FPSO production line, which already has an order book for 8 units. Petrobras has launched today the Rio Grande Naval Complex, in the city of Rio Grande, southern state of Rio Grande do Sul. The complex is considered so vital to the Brazilian pre-salt production that the outgoing president of Brazil, Luiz Inácio Lula da Silva was in attendance. The complex consists of a 430,000 m² infrastructure designed for the construction and repair of offshore units for the O&G industry. The complex will be capable of building drillers and production rigs.
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.
ROV Demand Still Increasing in Brazil
With a number of new O&G discoveries popping up nearly continuously in Brazil, both in shallow and deepwater, there has been a significant increase in ROV demand by operators, not only the major players but by all players involved on the Brazilian oil boom. In general the delivery of a complete ROV system may take around nine months, this includes the delivery of key equipment such as heavy duty winches, power and control umbilicals, flotation foam blocks, control modules, tooling kits and backup equipment. Here in Brazil, ROV manufacturers, which are basically all foreign companies with local offices, have been increasing their local stocks of ROV systems.
OSX looking at building drill rigs for Petrobras
With the work on its new shipyard underway, OSX, the shipbuilding and ship rental company belonging to the EBX Group, is planning on entering tenders in order to try and get a piece of the contracts for 21 drillers for Petrobras. The OSX shipyard is being built within the Açu Port area (the Açu Port is also in construction and is also owned by the same EBX Group). Sete Brasil is administering the construction of the 21 drillers, which will then be leased to Petrobras. Petrobras itself will oversee the tender process. Sete Brasil is one of the local companies participating in the tender and they have already been awarded the contract for construction of the seven first drillers, which are being built at the Atlantico Sul shipyard in the Brazilian northeast state of Pernambuco.
Saipem Going Strong in Brazil and Expecting more Growth
Eni owns 43% of Saipem, which is organised in three Business Units: Offshore, Onshore and Drilling, with various activities in remote areas and deepwater. Saipem is also specialized in providing engineering, procurement, project management and construction services. In 2010 Saipem was awarded by Petrobras the EPIC contract for the P55-SCR project, encompassing the engineering, procurement, transportation and offshore installation of flowlines and risers serving the semi P-55 to be installed in the Roncador field, in the Campos Basin, off the coast of the Rio de Janeiro State, in Brazil. For this contract Saipem will be working with companies specialized in subsea construction, such as Advanced Subsea and others, while utilizing various subsea support equipment, such as AUVs and ROVs.
Guará Pre-salt EWT Halted due to Subsea Production Pipe Failure
Like I recently stated, bad thing happen real fast, in this case no one even knows exactly why things happened but no real harm was done since the Dynamic Produce FPSO, belonging to Brazilian contractor Petroserv, was down for maintenance since last Sunday, with the well being plugged and the pipes purged of O&G. Therefore, when the a pipe section connecting the FPSO to the well ruptured (it´s still not clear at what depth the rupture occurred or even how many ruptures there were), there was nothing in them to spill out, avoiding what would have been the first serious pre-salt production accident resulting in a oil spill. It is also…
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.
Wellstream the Leading Flexible Riser Manufacturer in Brazil
