ABSTRACT
Miocene carbonate buildups
are extensively developed in the Luconia Province offshore Sarawak, Malaysia.
Some 200 carbonate buildups have been seismically mapped. In the early
exploration days, the carbonate structures were mainly defined using 2-D
seismic data.
The advances of 3-D seismic
data allow seismic attributes to be used in the development of carbonate
gas fields, both for structural mapping and for stratigraphic interpretations.
Both vertical and lateral porosity variations in carbonate reservoirs can
be calibrated to seismic amplitude and acoustic impedance. This paper outlines
a method that highlights the relationship between the thickness of the
reservoir and seismic isochore values. These techniques can be used to
select the optimum location for development wells. |
