Abstract: The seismic data in EP18 acquired in 1990 and 1991 was reprocessed in 1992. This report presents an interpretation of the reprocessed data. Four seismic horizons were interpreted: the Base Cambrian Unconformity, the Near Top Jamison Sandstone Seismic Marker, the Base Jamison Sandstone Unconformity and the Top Moroak Sandstone. The tops of the two sandstone units and the Base Jamison Sandstone Unconformity are mapped in depth. Isochrons of the seal units, Hayfield Mudstone and Kyalla Member, are also included. The structure maps of the top and base of the Jamison Sandstone shows larger variations in relief than the top of the Moroak Sandstone. Four conceptual models, wrenching; thinning; unconformity topography at the base of the Jamison Sandstone; and bar sand, are presented as possible explanations. However, the variations could also be due to noise in the data.
