CAMEROON OBJECTIVES

• Cameroon objectives are
• Domestic gas market supply
• Lpg and condensate supply to local market and
  export of excess
• Export of dry gas to eg lng train 2

4
CAMEROON GAS RESERVES

• Cameroon is unexploited in term of gas
• Non associated gas 5,5 Tcf (156 billion m3)
• Associated gas 0.035 TCF (1 billion m 3)
• Non risk exploration about 20 Tcf (570 billion
  m3)

5
CAMEROON GAS MASTER PLAN

• Following the gas master plan, three main
  development cases were studied
• RDR scheme 1
• This development scheme comprised the kita, edem
  and ekoundou fields
• RDR scheme 2
• This case consisted of developing the
  non-associated gas and associated gas in the
  wider kita area and also the northern fields
• Greater gas development scheme 3
• This case consisted of developing all discoved
  gas fields in cameroon that were perceived to be
  economically developable

CONCLUSION

• A LARGE INTEGRATED GAS EXPORT DEVELOPMENT WOULD
  PROVIDE THE BEST LONG-TERM PLATFORM FOR GAS
  COMMERCIALISATION FOR THE COUNTRY AND FOR
  DELIVERY OF COST-COMPETITIVE GAS POWER GENERATION
  IN CAMEROON.
• ANY GAS DEVELOPMENT, EVEN SMALL, DECIDED BEFORE A
  BETTER UNDERSTANDING OF VOLUMES HAD BEEN
  DEVELOPED COULD ERODE THE LIKELIHOOD OF
  LARGE-SCALE DEVELOPMENT SEEKING TO MAXIMISE THE
  UTILIZATION OF CAMEROONS GAS RESOURCE OVER A
  PERIOD OF 20-30 YEARS.

15
CONCLUSION

• DUE TO THE INSUFFISANT PRODUCTION OF LPG WITHIN
  THE COUNTRY, THE BEST SCHEME IS THE GREATER ONE
  WITH LIQUID RECOVERY IN CAMEROON AND LEAN GAS
  SENT TO EG LNG AT PUNTA EUROPA IN BIOKO ISLAND.
• TO PROGRESS A SUCCESSFUL CAMEROON
  COMMERCIALISATION SCHEME, SUBTENTIAL ADDITIONAL
  VOLUMES WOULD NEED TO BE MATURED AS SOON AS
  POSSIBLE THROUTH DEDICATED GAS EXPLORATION AND
  APPRAISAL ACTIVITIES.
