| 總結: | Nika Field is one of the oil fields in the South Sumatra Basin. This research analyses facies,
depositional environment, structure, geometry, properties dan hydrocarbon reserves of
Reservoirs S dan W in the field. The data employed are from 11 wells. The method used includes
the application of sequence stratigraphy concepts dan three-dimensional (3D) static geological
modelling.
In the study area, there are six lithofacies: very fine to fine bioturbated sandstone (Sb), fine
parallel laminated sandstone (Sp), mudstone – parallel laminated siltstone (Mp), mudstone –
lenticular siltstone (Ml), mudstone – massive siltstone (Mb), dan cross-laminated sandstone (Sc).
These six lithofacies can be grouped into three facies associations: tidal sand bar, sand flat, and
mud flat which were deposited in a tide-dominated estuary environment. The results of the 3D
static modelling reveal an estimated hydrocarbon reserve of ~66.1 to 70.45 MSTB for Reservoir
S dan ~22.3 MSTB for Reservoir W |
