Sand Injectites - Research Project

Mission

The project aims to document the characteristics of remobilised sands and to understand their causes and consequences.

The project will be carried out through a multidisciplinary approach provided by the integration of outcrop, subsurface and petrophisical data.

The Sand Injectites - Phase 2 Research Project started in October 2005. The objectives of the this phase is:

1. Timing of sand injection
2. Depth of burial
3. Geometrical organisation and spacing of intrusions
4. Relationships between parent sand bodies and intrusions
5. Sand injections and long-term basin flux
6. Relationships between in situ stress and sand body geometry
7. Petrophysical characterization of injectites
6. Reservoir modelling
7. Fluid Mechanics of injectites

The research project has its roots in the Sand Injectites - Phase 1 Research Project which has been concluded in 2002.While many of the results are confidential and embedded in the Phase 1 Final Report, the key published outcomes are listed below:

Defined classes of reservoir scale sandstone intrusion as conical sheets and wings, with seismic identification criteria for each class.

Defined core recognition criteria, with guides to separating injection and remobilization facies and discrimination from mass flow deposits.

Defined textural (poroperm) and petrophysical differences between injectite facies and depositional facies to aid in log interpretation and reservoir modelling.

Defined generalized basin models for remobilization-intrusion system to allow prediction in an exploration play context.

Defined role of injectites as long-term fluid migration conduits through isotope geochemistry and petrological analysis.

Defined relationships between intrusion and host caprock sequences especially in areas of polygonal faulting.
