3D GEOLOGICAL MODELING OF RESERVOIR X ANDY OF SAMARANG FIELD, SABAH, MALAYSIA

There are two mam objectives of this study; first is to model two reservOirs of
Samarang Field using RMS software version 8.1.1 and serves as the work platform of
dynamic modeling later on. Secondly is to calculate its Initial Hydrocarbon In Place to
have an idea of the remaining quantity potential left in the reservoirs. In order to
characterize the reservoir, geostatistic methods were used such as numerical detailed
reservoir description, 3D geological reservoir static modeling and dynamic
simulations. These techniques indeed make possible to simulate the reservoir internal
heterogeneity by respecting the well data and by offering the possibility to integrate
the seismic, production data and moreover allows associating with the uncertainty
result obtained. The work methodology consist of the following main steps started
from database building and quality control, building structural framework,
stratigraphic modeling, facies modeling, petrophysical modeling and volumetric. The
main result of this study is approximately coherent with the result of dynamic
synthesis in this case calculation of material balance which has done independently.
