A 2015 appraisal drilling program saw three wells drilled in the NTRL5 permit area. Results from two of the appraisal wells were in line with expectations, with one well at the higher end of the expected range.

A new 3D seismic acquisition program was completed over both permits in 2016.

A further two appraisal wells, Barossa-5 and Barossa-6, were drilled in NTRL5 in 2017.

These results better informed us of the size and quality of the field. The data obtained from the appraisal program was integrated into subsurface models to support the FEED entry decision.
