| Summary: | Iliran-Kluang structure is a paradox inside the Rimau Blok. A major NW-SE trending
structure which controlling regional geology frameworks has yet to be geology
structure understood. Therefore the main goal of this study is to evaluate evolution
model of Iliran-Kluang structure through different tectonic regimes and its impact to
petroleum system in Rimau block. Structure mapping and palinspatic reconstruction
has been conducted to analyze the evolution and the behaviour of the structure. Most
of the deformations histories in the Rimau block are characterized by complicated
structural pattern, therefore depend on seismic interpretation only is insufficient to
constrain unique structural interpretation.
The results and analysis of palinspatic reconstruction indicate that there are two
deformation styles observed across study area. The deformation are extension event
occurred from Pre-Tertiary to MFS-10 at Early Miocene then the shortening event
occurred after SB-11 at Middle Miocene. Strain analysis of both deformations phase
within the basin indicate variation of strain values. The extensional and shortening
strain axes consistently show relative NE-SW and NW-SE of direction both during
extension and contractional deformations. Therefore, the evolution of basin and
structures in the Iliran-Kluang are closely relate to continuous strike-slip fault system
from Pre-Tertiary to Recent time.
The exposure of Iliran High basement area during syn-rift and poly-phase
deformations over the region has increased the potency of fractured basement
reservoir developed in the area. An exploration play concept of fractured basement
reservoir has been build to summarize all petroleum system components which have
to be considered to explore this unconventional play. |
