Genetic relation of C02 and its suitable usage in the Peninsular Malay Basin.

Reservoirs with high C02 content are connnon throughout the Asia Pacific region,
notably the Gulf of Thailand, Malaysia, Indonesia and Vietnam. In Malay Basin,
C02 production ranges from 5 to 90% mol. The high production of C02 is
concentrated in certain region in the Malay Basin. The most notable high
production of C02 is the northern region near Thailand and the center of Malay
Basin. The comprehensive study on C02 genetic relation and its source haven't
been established yet. For this project the authors have studied the origin of
produced C02 in order predicts the continuous supply for field development
program. The author also made a comprehensive study on the tectonic framework,
stratigraphy, various plays and geothermal gradient of Malay Basin to relate with
the existence of associated gas. For the development program EOR operation is
preferable among others since it is the suitable due to numerous of C02 supply
from the field. The C02 flooding operation will be discussed in this report where
the details modeling for reservoir and well are established to predict the
performance of the reservoir with C02 flooding. Results from the modeling
indicate C02 flooding as EOR may be suitable for further development plan to
increase the production of oil up to 20 % from naturally flow well. In the fmal
chapter of this report, the author relates the statigraphy, heat flow and plays in
Malay Basin to conclude the finding on origin of C02 in Malay Basin. The high
production of C02 is mainly originated from inorganic origin while low
production of C02is from organic origin; The isotopic value of o 13C is used to
distinguish between these two types of C02.
