Abstract
Summary
Two continuous cores from a partially dolomitic, isolated platform in Central Luconia, Malaysia, have been newly described and analysed with data based on thin sections, poro-perm measurements, and a suite of logs, including compressional velocity, density, and neutron porosity. To improve reservoir characterisation, sequence stratigraphy and rock physics have been combined, working toward integrated carbonate reservoir rock types. Dolomitic rock types form the principal reservoir units. Preliminary results suggest the preferred dolomitisation of reefal associations dominated by massive and branching corals, which formed during decelerating sea level rise, stillstand, and eventual fall.
