History

  • 1988 - Cangoá Field is discovered
  • 1996 - The Peroa Gas Field is discovered
  • 2006 - Peroa gas field production started
  • 2006 - Aker Kvaerner awarded subsea contract for phase II development
  • 2009 - The Cangoá Gas Field starts production

Geology

  • The main Peroá reservoir is channelized Oligocene turbidites sandstones deposited in the base of escarpment toward diapirism salt channels. Petrophysics and log data point out good to very good porosity (17% to 24%) and gas permeability (50 mD to 200 mD), Sw from 15% to 36% . Original reservoir pressure is from 209 and 290 kgf/cm2, 2460 to 2700 m TVD.
