Devon Energy has informed ANP (Brazil´s National Petroleum Agency), that it has discovered indications of hydrocarbons in block CM-471 at the Campos Basin. This block is operated by Devon in a 50%/50% partnership with Brazil´s national operator Petrobras.Block CM-471 was acquired by Devon and Petrobras back in 2005, during ANP´S 7 round of bidding along with block C-M-473, both making part of block BM-C-34. Earlier this year Devon had disclosed the existence of potential O&G reservoirs in the adjacent block BM-C-32. Devon plans to extend the drilling in both blocks down to the pre-salt depths. Well 6DEV18PRJS in block CM-471 is located at a depth of 2,484 meters, being one of the deepest of the deepwater wells in Brazil.

Petrobras has announced it will start producing today the first oil from the pre-salt layer of the Baleia Franca Field, which is located about 85 km from the city of Anchieta (state of Espírito Santo), in the Parque das Baleias area.The Baleia Franca Field´s pre-salt accumulations were discovered in December 2008. The Production will start through the connection of well 6-BFR-1-ESS to the FPSO Capixaba, chartered to Petrobras by SBM and previously operated in the Golfinho Field. Aiming to anticipate the production at the Cachalote and Baleia Franca fields, the platform was moved to Parque das Baleias, after some changes in its process plant. The Baleia Franca pre-salt well will start producing approximately 13,000 bpd of light oil, estimated at 29º API.

New Discovery Confirms the Campos Basin Pre-Salt Potential

September 27, 2010

newdiscoveryconfirmsthecamposbasinpresaltpotential
The recent discovery of hydrocarbon accumulations under the Albacora Leste field´s pre-salt layer confirms there potential of the Campos Basin to be a significant pre-salt producer.The recent oil discoveries in pre-salt layers under certain Petrobras concession areas in the Campos Basin are already being considered significant and tend to offer the possibility of production start-up in a much shorter time frame than the major pre-salt discoveries in the Santos Basin. This is due to the fact that the fields under which these new discoveries are located already have production infrastructure in place and whatever new subsea wellheads are installed will only need to be connected to one of the FPSOs, FSOs or rigs already in place.

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.

May 21, 2010

presalttechnologicalchallengesimg
Although not considered a major challenge by Petrobras, drilling two thousand meters below the water line, through about three thousand meters of sediments, and through two thousand meters of salt is done at the frontiers of technology.Drilling at a depth of two thousand meters is not a problem. Petrobras already has several wells at this depth, in Brazil and in the Gulf of Mexico, and produces at 1,886 meters in the Campos Basin, a mark that was once the world record (Shell currently holds the record, at more than two thousand meters from the water line in the Gulf of Mexico). The biggest challenge is the layer of salt, which, under high pressure and at high temperatures…

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.

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.
