Deepwater Well-Control Aspects for Slender-Well Drilling

The 2003 Brazilian deepwater drilling record was achieved with a slender well in 9,475-ft water depth in Campos basin. The well was drilled safely with a surface-blowout-preventer (SBOP) system. The full-length paper details two discussions. The first is on technical issues concerning well-control operations on the drilled well and on a hypothetical conventional well. The second is on aspects of the SBOP technology. The main objective was to broaden discussion regarding application of the SBOP concept to explore and develop deepwater and ultradeepwater reserves in Brazil, with emphasis on well control.
