Research Projects

The general theme of staff and student research in Petroleum Geoscience is Reservoir Studies. Specific topics that are currently being investigated are:

Facies models for sandstone reservoirs deposited in deltaic and shallow marine environments in tropical climates:
Conventional facies models for deltaic and shallow marine sandstones do not apply to tropical environments, especially within the semi-enclosed seas common to SE Asia. New models for predicting reservoir geometry, porosity and permeability will be developed from outcrops, modern systems and cores that can applied to subsurface reservoirs.
Principal Investigator: Joseph J. Lambiase

Fractured reservoirs of SE Asia:
Fractures in reservoirs are being increasingly recognized as significant controls on reservoir quality and producibility in oil and gas fields in SE Asia. This is true across a broad spectrum of producing lithologies in the region that encompass carbonates, granites, volcanics and siliciclastics. Many such SE Asian oil and gas fields are located in tectonically active settings where a combination of tectonics, subsidence and sedimentation controls both the position and diagenetic history of the relevant petroleum system. The aim of this research is to build a multidisciplinary group that will address the question of reservoir quality prediction in such fractured systems in the SE Asian region.
Principal Investigator: John K Warren

Seismic resolution of thin-bedded sandstones:
The seismic identification of potential sandstone reservoirs is becoming more difficult as the targets become thinner and less clean. Seismic inversion techniques will be assessed to improve resolution of these types of reservoirs, and linked to an assessment of sand body geometries within these depositional systems.
Principal Investigator: Philip Rowell

Syn-rift clastic reservoir facies:
Syn-rift reservoirs are an emerging reservoir play, especially in SE Asia. However, their depositional systems and reservoir properties are not well understood as there has been little advancement from facies models originally derived in the 1980s. These models will be updated from outcrop and core studies to enable better subsurface prediction.
Principal Investigator: Joseph J. Lambiase

World-scale controls on the evaporite-carbonate trap/reservoir association:
Evaporitic sediments, which constitute less than 2% of the world’s Phaneozoic sediments, are associated with more than 50% of the world’s known hydrocarbon reserves hosted in Phanerozoic strata (with evaporites most important as seals and halokinetic traps in the relevant petroleum systems). Quaternary evaporite deposits constitute less than 0.1% of the Holocene sediment volume. Clearly there were times in the past when evaporite deposition was more widespread and more voluminous than today. By an integration of GIS datasets and time-based paleogeographic reconstructions this research project aims to better understand the dichotomy of past and present evaporite distributions and so better understand and predict the hydrocarbon-evaporite association.
