| Summary: |
In the oil and gas industry, basins containing fractured basement have garnered much
interest due to the fractures’ potential as a hydrocarbon reservoir (Sircar, 2004)
through its secondary porosity. However, since these basements are typically made
of meta-sediments or igneous rock located at a deeper depth, it is difficult to analyze
the fracture network based on seismic images, due to poor resolution (attenuation of
higher frequency, and lack of sedimentary layers with contrasting acoustic
impedance). Thus, imaging, locating and interpreting the fracture network within the
basement proves to be a challenge, and results in a higher risk of inaccurate drilling
decisions to be made. Having surface outcrops which can serve as a good analogue
to the subsurface provides an opportunity for in-depth studies at a fraction of the cost
for well-based studies. Hence, this study aims to image the basement fractures in
Anding field better through seismic processing, and correlate them with the fractures
found on onshore outcrops at the coast of Terengganu, peninsular Malaysia. |
