Acquisition Report and Processing Report Imperial Broadmere 2019 2D Seismic Survey

Abstract

The onshore 2019 Broadmere 2D Seismic Survey was acquired within EP187 in Northern Territory between 2nd October 2019 and 12th November 2019. Velseis was the seismic survey contractor which acquired six lines totalling 223.24km.

The field records indicated the presence of reasonable signal at the target reflectors. Issues observed with surface volcanics in other parts of the Beetaloo Sub-basin were not observed over the survey area. This was due to the absence of surface volcanics, not through data acquisition.

Velseis Processing processed 223.24km of seismic data from the Broadmere 2D Seismic Survey in the Northern Territory. The processing was undertaken during November and December 2019 and were processed through a standard Trim Stack/FD Migration sequence as well as a Pre-stack Time Migration (PSTM) sequence.

The seismic data of the 2019 Broadmere Seismic Survey recorded in EP187 for Imperial Oil was of a high quality. This was most likely due to the use of Velseis' 80,000lb Renegade vibrators which provided sufficient power for deep signal penetration.
