PESA QLD Lunch, 24 October : Where comes the gas from, where does it go? – Southern Denison Trough CO2 storage possibilities from a geological perspective

This month PESA Queensland welcomes Alison Troup to present a technical luncheon looking at the CO2 storage potential of the southern Denison Trough.

The Technical Lunch will be held at the Brisbane Hilton Hotel, in Room 83 (Level 8).

For detailed directions, see explanation below.

Please note the Early Bird ticket pricing cut-off times described below.

Presentation Abstract:

The southern Denison Trough contains several depleted conventional gas fields, mostly reservoired in the Aldebaran Sandstone with secondary reservoirs in sandstones of the upper Reids Dome beds. These gas fields are naturally high in CO2 and may present a good opportunity from a geological perspective for CO2 storage. In support of this an updated interpretation of the depositional environment at Merivale, Westgrove, Yellowbank and Punchbowl Gully has been developed to examine changes in depositional environment along the Aldebaran Sandstone paleocoastline. Comparison of the production history of Merivale to the variability in the depositional environment shows that there is strong contribution from the depositional environment to production behaviour.

Sandstones and coal seams in the upper Reids Dome beds may present a secondary target to depleted gas field storage in the southern Denison Trough. Gas distribution in the Reids Dome beds coals shows that the Hutton-Wallumbillla Fault may be a migration pathway for magmatic CO2 into the unit. High CO2 concentrations and saturations within these coals demonstrate a natural analogue for storage within this system. The stratigraphic placement of these coal seams has been improved through the use of stable carbon isotope analysis.

Tickets for the Technical Luncheon can be purchased below.

Please be advised of the early bird cut-off date.

Early bird pricing will now remain available up until Monday, 21 October 12:00 PM after which, standard pricing will come into effect.

To avoid disappointment please register before that date and time.

Late ticket sales up to Wednesday, 20 October 12:00PM will be available for $95 for all tickets – subject to availability. Please note dietary requirements can not be guaranteed for late tickets.
