Conclusions (Cont...)

• 4. Future Exploration Should Focus on the NW
  Portion of Ex Block 78 (KARENE AREA and
  Further NW)
• Area With Less Burial History, Ro 0.5 Ro in Late
  Permian Shales
• Better Conditions to Discover Liquid
  Hydrocarbons Permian Ene
• Better Reservoirs than in Candamo
• 23 Porosity and 2-4 Darcies in Cretaceous

CONCLUSIONS

• Area adjacent to Candamo gas/condensate
  discovery
• 3 TCF and 120 MMBC
• Cretaceous/Permian reservoirs (Camisea)
• Proven triangle zone extends to Karene

• Remaining 16 prospects and Leads
• 9 in tested Candamo Triangle Zone
• Five in untested Frontal Thrusts (Camisea)

• High potential to find additional prospects with
  denser seismic grid

• Most prospective area in the FTB of Madre de Dios
  Basin
• High potential to find oil
• Excellent reservoir character
