Depositional environments, diagenesis, and porosity of reservoir sandstones in the Malong Field, offshore West Malaysia

Abstract

Reservoir interval (?lower Miocene; c. 1500 m depth) includes three main types of sandbody: prograding shoreface; shallow marine; fluvial channel. Porosity and permeability primarily related to depositional environment; highest in fluvial channel and offshore shelf. Shoreface deposits slightly lower.
