Western Tasmania Regional Seismic Data, Selected Reprocessed Lines from Seismic Surveys T69A and T70A

As part of the Commonwealth-funded Western Tasmanian Regional Minerals Program (WTRMP), Mineral Resources Tasmania (MRT) initiated a collaborative study of the offshore northern and western Tasmania (Figure 1), in partnership with Geoscience Australia (GA) and the National Centre for Petroleum Geology and Geophysics (NCPGG). Commercial inputs into the project were sought from Biostrata Pty Ltd, SRK Consulting, Fugro MCS and CSIRO. The aim of this work was to enhance the petroleum prospectivity of the northern and western regions of offshore Tasmania through an improved understanding of basin geology, an integrated petroleum systems analysis, and enhanced access to basic datasets critical to the exploration industry.


One issue raised during the scoping phase of the WTRMP projects was the limited availability of low-cost seismic data along the frontier margin of offshore western Tasmania. While a broad regional grid of vintage industry data existed, most of the data was not accessible in a digital format due to the condition of seismic field tapes and reports. This data was viewed as valuable in assessing prospectivity and play concepts in this frontier area. A module of the WTRMP was aimed at addressing this shortfall in information.


This Record (CD-ROM) contains SEG Y files of reprocessed seismic data for 12 lines from industry surveys T69A (1969) and T70A (1970) across the Sorell Basin, offshore western Tasmania (Figure 2). The data includes seven lines from Survey T69A and five lines from Survey T70A, for a total of 511.98 line kilometres of data (Table 1). The reprocessing job was commissioned by Mineral Resources Tasmania and coordinated by Geoscience Australia during 2001-02. The work undertaken by Geoscience Australia included access to seismic field tapes lodged in the Petroleum Data Repository under the Petroleum Submerged Lands Act (PSLA) 1967, management of contracts and QC/acceptance of the final dataset. Fugro Multi-Client Services (formerly Seismic Australia) and Robertson Research Australia Pty Ltd carried out the reprocessing as part of a commercial contract (Robertson Research Australia, 2002). Digital files of navigation (ASCII format), velocity data (WESTERN format) and a reprocessing report (PDF format) have been included with this Record. A simplified digital basemap is also included in JPG format.
