This Event is Proudly Sponsored by TGS:

PESA WA invites you to their October Young Professionals Speaker Night. This is the perfect opportunity to socialise with your industry peers and enjoy two technical talks given by Xuemei (Linda) Yang (Curtin University) with a second speaker TBA.

Talk 1: Xuemei (Linda) Yang

Gippsland Basin 3D forward modelling in Badlands 

Abstract:

The Gippsland basin geological history is modelled using the Badlands software constrained by a realistic 3D structural and stratigraphic model built in Petrel.  The aim is to assess and calibrate the theoretical tectonic and sedimentary models using empirical data for a rift basin.  The theoretical models are used to assess and measure the relative effect of significant variables for sedimentary basins, including climate, extension, subsidence, uplift, erosion and sedimentation.

The modelling results indicate several insights for the Gippsland Basin.  The initial paleo-topography at ~145 Ma was an extensive highland area.  The Early Cretaceous paleo-environment was intracratonic, with sediment transport from east to west, and at some stage included an inland sea. The Mid Cretaceous uplift caused emergence of the entire basin, substantial regional erosion and changed the basin architecture. Subsidence associated with Tasman Sea rifting formed the Central Deep and flipped the fluvial paleo-drainage system towards the east. Latrobe Group sediments filled the basin being progressively transgressed by rising sea level to flood most areas by the Oligocene. The models simulate the progradation of the carbonate shelf sediments, sub-marine channels and anticlines over the basin since then.

Key words: Gippsland Basin, Badlands, 3D basin modelling, palaeotopography, basin evolution.

 

Biography:

Xuemei Yang is a PhD Candidate in Petroleum Geology at Curtin University. She obtained a B.Sc. (Hons) in Petroleum Geology Engineering from China University of Petroleum, Beijing and a M.Sc. in Geology from Curtin University. She is interested in 3D basin modelling, basin analysis and petroleum geology.

Xuemei has participated in projects like “Diagenesis characteristics of sandstone reservoirs in Liaohe Oil Field”, “The thermal and tectonic history of typical superimposed basins” in China and “Structural evolution of the Gorgon Platform, North Carnarvon Basin, North West Shelf” in Australia.

 

Talk 2: Christian Proud

Improved Interpretation of large, near-field exploration Ocean Bottom Datasets

Abstract

Ocean bottom seismic has seen a renaissance in recent years. Acquisition companies have developed technology for faster deployment and recovery, more innovative shooting geometries leveraging increased sensor inventories, compressive sensing and simultaneous sources. It has thus become more economically viable to acquire larger near-field exploration ocean bottom datasets. Reservoir areas obscured by gas anomalies are a common challenge in South East Asia. Extensive AVO compliant preconditioning and a simultaneous PP-PS elastic inversion enable a clearer reservoir interpretation in the gas obscured areas. This is demonstrated by improved well ties over the PP inversion and by more geologically consistent elastic properties within the layers. In our case study, we demonstrated that density estimated from PP-PS simultaneous inversion of multicomponent seismic data is superior to one obtained from PP (P-wave only) seismic inversion. Superior results are obtained even in the gas cloud areas. The density estimated from PP-PS simultaneous inversion was used in reservoir delineation and characterisation.

Biography

Christian obtained a Bachelor of Science (Geophysics) with first-class honours in 2016 from Curtin University. He has been working as a Geophysicist at Qeye since 2017 and has completed a variety of quantitative interpretation studies including multicomponent, 3D and 4D simultaneous AVO inversions within Australia, New Zealand, West Africa and Malaysia.

Christian’s particular interests include rock physics, 4D quantitative interpretation and probabilistic inversion methods.
