The terrane model was applied early in its inception to parts of the Pacific margin of Gondwana (Coombs et al 1976;Bradshaw et al 1981;Weaver et al 1984;Murray et al 1987). Now it is accepted almost universally that terrane-style tectonics are of major importance in the development of orogenic belts.…”

The Walloon Subgroup (WSG) represents a prolific coal seam gas (CSG) resource which, in part, underpins three large CSG to liquefied natural gas (LNG) projects operating along the Australian east coast. These mega-projects require long term forecasts of gas production, predictions which are often derived via the dynamic simulation of numerical reservoir models. Reservoir models consist of hierarchical collections of inter-related rock and fluid parameters. The facies model, representing palaeogeography, serves as the foundation of this linkage as it defines the three-dimensional (3D) geometry and distribution of coal seams. This thesis is comprised of complimentary studies aimed at investigating and enhancing the predictive capability of numerical facies models in the Walloon Subgroup.A preliminary screening study investigates CSG production behaviours to understand how reservoir parameters, including the distribution and continuity of coal layers, impact the predictions output by reservoir models. A database of open-source reservoir properties was compiled and used to construct representative reservoir models for three CSG development areas present along the WSG productive fairway in the eastern Surat Basin. Simulation experiments using these models confirms that the distribution and lateral continuity of coal facies are a significant control upon the late-stage production behaviour of CSG wells -a finding which provides impetus for further detailed investigation of WSG facies models.Construction of predictive facies models requires a comprehensive understanding of regional depositional trends, local facies architectures and depositional processes as well as computer routines able to translate this information into numerical 3D grids. Present gaps in the industry's understanding of the WSG highlight the requirement for further studies aimed at 1) refinement of the WSG's regional stratigraphic and palaeogeographic models, 2) delineation of the WSG's reservoir scale internal alluvial architecture, 3) identification of the processes or mechanisms controlling reservoir-scale facies relationships within the WSG and 4) development of workflows better able to represent alluvial facies in numerical reservoir models. The focus of this dissertation is to explore these conceptual gaps leading to improved numerical facies models of the WSG.Investigation of WSG facies models began with a regional study integrating newly available borehole image log data with sedimentological interpretations from cored wells and regional correlations to test and refine existing basin-wide palaeogeographic models for the WSG. This analysis offers a glimpse into fluvial styles and palaeoflow orientations present within the basin's interior and was 2 used to identify regional trends describing the spatial and temporal distribution of alluvial depositional styles. Synthesis of stratigraphic, sedimentological and palaeoflow interpretations developed during this study suggests the presence of a SE oriented trunk drainage system during depo...

“…The NEO is the easternmost and youngest component of the Tasmanides (Glen 2005), and its formation was mainly associated with supra-subduction processes from the Devonian to Triassic (Leitch 1975, Murray et al 1987. The majority of the exposed rocks belong to a Devonian-Carboniferous subduction system, and include, from west to east, arc-related, forearc basin and accretionary complex rocks.…”

Subsurface architecture of the Texas Orocline and its influence on in situ stresses in the overlying Surat Basin

Abstract:The New England Orogen in eastern Australia is a curved orogenic belt, with the Texas orocline being the most prominent curvature. The majority of the Texas Orocline lies beneath Permian to Mesozoic sedimentary basins (Bowen and Surat basins), which inhibit primary observation of the three-dimensional geometry of the orocline and its possible tectonic origin. The Bowen and Surat basins have recently been the target of coal seam gas exploration and production. Coal seam permeability is primarily influenced by fracture/cleat interaction with in-situ stresses. Permeability distribution appears primarily influenced by first order crustal scale structuring regardless of whether structures intersect actual coal bearing basins or whether structures terminate below the producing basins.The apparent influence of crustal structures, stress and ultimately coal permeability highlight the need for studies on the crustal architecture and its influence on the in situ stresses within the overlying basins. Consequently this thesis presents geophysical and well data that constrain the geometry and evolution of the Texas Orocline under the sedimentary cover, and characterize in situ stresses in the overlying basins.2D seismic, aeromagnetic TMI and Bouguer Gravity are used to identify the depth to the New England "basement" and to locate significant faults intersecting it. These data are used to produce a structural interpretation of the curved New England Orogen below cover, as well as a tectonic model for its formation. The orientation and magnitude of in situ stresses with relation to basement structures are mapped across the Surat Basin using wireline log data. The stress state ii across the entire Surat Basin is observed as highly variable, with a mean E-W maximum horizontal stress orientation. Locally, stresses rotate from WNW-ESE over the Lachlan and Thomson Orogens on the western margin of the study area, to NW-SE over the New England Orogen on the eastern margin of the study area. This is in stark contrast to previous studies of the stress state in the Bowen Basin to the north, which exhibits a consistent NNE-SSW maximum horizontal stress orientation. Differential tectonic stress is observed to increase with proximity to basement intersecting faults (Leichhardt-Burunga Fault System) and areas of uplifted basement. Additionally, Andersonian tectonic regimes are observed to change with depth from reverse, to strike-slip, to normal where sedimentary cover is thickest. This stress field complexity is attributed to complex boundary forces associated with Indo-Australian Plate collision being preferentially transmitted within basement lithology over basin lithology due to basement exhibiting a higher rigidity. Local structure is more influential than plate boundary forces on the in situ stress state of the study area due to its location within an "area of divergence" in the Brooke-Barnett, S., Flottmann, T., Paul, P.
