PEP 381200 Seismic Interpretation Report

This report summarises the seismic interpretation in PEP 381200 for the period June 2008 to August 2011. The interpretation incorporates the newly acquired 2D MSS data of the OMV07 survey. The aim of the interpretation was to provide greater definition of the Vulcan-Hestia lead, a four way dip closure formed by the compaction drape of Late Cretaceous sediments over a Late Cretaceous extrusive volcano. Two separate depth closures exist at the Late Cretaceous level. Vestia with a 160.4km2 closure (LCC 3500m) and Hestia with a 232.4km2 closure (LCC 3510m). The key geological risk factors in the permit are reservoir presence and charge. Recommendations for reducing uncertainty on these key risks include the acquisition of 3D seismic data over the lead, acquisition of a 2D tie line to the Tane-1 well and incorporation of any additional well data that may become open-file.
