Abstract: Calculating hydrocarbon reserves in a reservoir sequence where the productive sands range from decimetres to only millimetres in thickness is very difficult using conventional downhole logging and core analysis methods. Petrographic image analysis (PIA) can be used to determine certain petrophysical parameters within these sands leading to more realistic estimations of both total and recoverable reserves.

Preliminary results from PIA analysis of twenty-four (24) samples from the Malay Basin are included to demonstrate how this new technology can improve reserves calculations.
