Calibration of charge and retention models for the Gidgealpa Oilfield: implications for seal potential in the Eromanga Basin
- Publication Name: PESA's Eastern Australasian Basin Symposium II
- Authors: L. Johnson, M. Lisk, A. Gartrell and P. Boult
- Reference Type: Book Section
- Date Published: December 2004
Abstract:
The hydrocarbon charge history of the Gidgealpa Oilfield has been investigated to test an existing trap integrity model proposed for the Hutton-Birkhead reservoir-seal couplet. Conventional oil show data have been supplemented with grains with oil in...
Top seal and reservoir continuity: hydrodynamic evaluation of the Hutton-Birkhead Reservoir, Gidgealpa Oilfield
- Publication Name: PESA's Eastern Australasian Basin Symposium II
- Authors: J. Underschultz and P. Boult
- Reference Type: Book Section
- Date Published: December 2004
Abstract:
The Gidgealpa Oil Field of the Eromanga Basin is characterised by stacked hydrocarbon accumulations where the
principle control on column heights is considered to be variable top seal capacities. The Hutton Sandstone forms the main reservoir at Middl...
Subsurface plumbing of the Crayfish Group in the Penola Trough: Otway Basin
- Publication Name: PESA's Eastern Australasian Basin Symposium II
- Authors: P.J. Boult, P. Lyon, B. Camac, D. Edwards and D.M. McKirdy
- Reference Type: Book Section
- Date Published: December 2004
Abstract:
The Penola Trough is host to five commercial gas fields containing an estimated 127 petajoules of gas, while seven, possibly eight, wells have intersected residual or palaeo-gas and oil columns. Most gas accumulations are, or have been, full to struc...
A review of basin evolution, sequence analysis and petroleum potential of the frontier Arrowie Basin, South Australia
- Publication Name: PESA's Eastern Australasian Basin Symposium II
- Authors: W-L Zang, J.B. Jago, E.M. Alexander and E. Paraschivoiu
- Reference Type: Book Section
- Date Published: December 2004
Abstract:
Cambrian sediments of the Arrowie Basin were deposited on a rifted continental margin on the southwest palaeo-Pacific part of Gondwana. Depositional regimes range from the western tectonically stable shelf, platform ramp to the eastern slope and trou...
Hydrodynamic analysis of the Early Cretaceous aquifers in the Barrow Sub-basin in relation to hydraulic continuity and fault seal
- Publication Name: The Sedimentary Basins of WA
- Authors: A.L. Hennig, J.R. Underschultz & C.J. Otto
- Reference Type: Book Section
- Date Published: December 2002
Abstract:
Formation pressure measurements from the Mardie Greensand and the Barrow Group were of sufficient quantity and quality to enable a hydrodynamic analysis of the flow systems to determine how flow systems interact laterally and across formations. This ...
Pressure seal and deep overpressure modeling in the Barrow Sub-basin, North West Shelf, Australia
- Publication Name: The Sedimentary Basins of WA
- Authors: S. He & M. Middleton
- Reference Type: Book Section
- Date Published: December 2002
Abstract:
A deep overpressured system occurs in the thick Jurassic sequence, and parts of the Cretaceous BarrowGroup of the Barrow Sub-basin. This has been confirmedby repeat formation tests and drill stem tests which reveal
excess pressures ranging from 24 MP...
Diagenesis impacts fluid pressures, reservoir quality, and seal integrity of deep Jurassic targets, Norwegian Sea
- Publication Name: The Sedimentary Basins of WA
- Authors: J.C. Matthews & H.M. Helset
- Reference Type: Book Section
- Date Published: December 2002
An Empirical Approach to Evaluating Regional Seal Capacity and Hydrocarbon Migration Characteristics in South-Eastern Australia
- Publication Name: Eastern Australian Basins Symposium 2001
- Authors: G.W. O'Brien, D. Heggie, G. Lawrence and A. Williams
- Reference Type: Magazine Article
- Date Published: November 2001
Abstract:
Over the last decade, the Australian Geological Survey Organisation (AGSO) and its industry partners have acquired and interpreted a wide range of geochemical and other remote sensing data in south-eastern Australia includincr aeochemical sniffer and...
Mechanisms of Dynamic Seal Failure in the Timor Sea and Central North Sea Basins
- Publication Name: The Sedimentary Basins of WA
- Authors: Richard R. Hillis
- Reference Type: Book Section
- Date Published: December 1998
Abstract:
The seals to hydrocarbon reservoirs in the Timor Sea and central North Sea often fail, despite being thick shales that should not be prone to capillary leakage. It is likely that fracturing of these seals, herein termed dynamic seal failure, contribu...
