Comprises details of the operations, field acquisition, results and interpretation of the seismic survey. A total of 1763 km of Vibroseis reflection seismic was recorded. In addition, a number of surveys were carried out for development purposes involving 643 km of 2D profiling (total includes ATP 259P in Qld) and three 3D surveys. Included are : i) acquisition and processing reports (Murta Development, Nappacoongee-Murteree Development, Patchawarra Southwest Development, Moomba Development, Toolachee Development, Patchawarra Central, Patchawarra East, Merrimelia-Innamincka Development, Lake Hope, and Gidgealpa South Dome interim); and ii) geophysical interpretation reports as detailed below. Separate geophysical interpretation reports were produced for each block, given area or prospect and contain a detailed discussion of the geology of the area, the existing geophysical information, the mapping technique used, and the results of the survey. Herein are: Patchawarra Southwest Block; Dirkala 3D; Strzelecki Block; Patchawarra East Block (Tallerangle/Streeton-Candra prospects); Patchawarra East Block (Keleary/James Shelf region); Naroonowie-Coobowie Trend; Moomba-Big Lake Reservoir Study - Revised Structural Interpretation; Toolachee Field Review - Post Toolachee 50; Bookabourdie Field; Kirrallee area; Patchawarra Central Block (including Wills and Duncan seismic surveys); Lake Hope 3D; and Gidgealpa Unit 3D.
