ConocoPhillips Australia is planning to undertake a three-dimensional (3D) marine seismic survey (Sequoia 3D seismic survey) in Exploration Permit T/49P to enable assessment of the natural gas reservoirs in the eastern offshore Otway Basin. The permit is located in waters west of Tasmania’s King Island.

In order to undertake the seismic survey, ConocoPhillips Australia is required to submit an Environment Plan (EP) to the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) for assessment. Only once NOPSEMA has accepted the EP can the seismic survey commence. It is anticipated that the seismic survey will be acquired in 2021. ConocoPhillips Australia has an 80 percent interest and operatorship of T/49P though a farmout agreement with 3D Oil Limited.
