tupicommercialproductionstartuptobeanticipated
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

brazilianpresaltfrontierstoexpand
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.

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.

September 27, 2010

kongsbergdpsystemoverviewimg
A look at how DP systems work and their importance to ships, vessels and rigs working on offshore O&G operations. The main contribution Kongsberg has made to the offshore O&G industry was by developing DP systems for diving support vessels in the 1970s. This significantly increased the efficiency and safety of diving operations. Since then, the offshore and maritime industries have benefited from the advances made to their DP systems. In more recent years these advances have been applied to the cruise industry with dynamic positioning systems for maneuvering and the complex task of precise position keeping. For optimal deepwater drilling the Kongsberg Riser Management System (RMS) assists in all phases of the drilling operation.

subseapowergridtoenablelargescalesubseaprocessing
The future of O&G recovery most likely lies in deepwater reservoirs. Subsea processing opens the door to more cost-efficient developments, especially for long step-outs and, marginal and deepwater fields. Large-scale seabed processing facilities will require a subsea power grid system that is able to operate for long step-outs with total reliability withstanding extreme pressure and temperatures. As technology leader on land-based power grids, Siemens has configured complex power transmissions to suite multiple subsea operations. Siemens also has broad experience with subsea power concept studies as well as experience producing deep-sea transformers and compressors and ten years experience on subsea control and communication.

The Cost of Deepwater E&P

September 27, 2010

thecostofdeepwaterep
This cost isn´t only in equipment and manpower, it´s in lives, human and animal and destroyed ecosystems which will take at least a decade to recuperate. Safety must always come first. Even with the most reliable equipment and redundancy, there will always be the human factor. Nothing like a full on environmental tragedy to make for a vital attitude change: Safety first, and then all the profit scene. We all know now, that there is no infallible safety measure, well not man proof anyway. Pressure seems to be a wee bit of a problem too. Like the old saying goes: You only knows, when it blows! Well now we know, don´t we? This is the worst case scenario and it could not be correctly simulated.
