    HD3D comes to Australia

    Projects and Operations // November 16, 2005

    PGS Asia-Pacific has recently embarked on a long offset HD3D survey for ENI Australia. 

    Ramform Victory is deploying a 12 x 6,000m x 50m dual-source streamer array. 

    The survey has already established several records: the longest streamer offsets, the most streamers deployed, and the largest trace density for a  HD3D survey acquired in Australia. 

    After the completion of the survey Ramform Victory will acquire a campaign of several other high technology surveys, including a HD3D-4D baseline survey.  This will be the first customized 4D survey ever acquired in Australia.

    The PGS HD3D-4D acquisition strategy delivers excellent repeatability. Dense streamer configurations are towed on regular pre-plot shot lines, complemented by streamer overlap to maximize source-receiver azimuth repeatability. 

    HD3D-4D will also provide the critical spatial sampling benefits required for successful data processing and imaging in the North West Shelf of Australia.
