The 2D seismic campaign was carried out with the Aquila Explorer seismic vessel and involved recording 3827 kilometres of 2D data with a 6km solid streamer recording cable in order to maximise imaging quality.
Neon said the survey was completed within budget and 16 days ahead of schedule.
"Initial indications are that the new data is of excellent quality and this will greatly enhance our prospect definition and ranking efforts," managing director Ken Charsinsky said.
Processing and interpretation of the new data is expected to be completed by the end of the year with prospects to be ranked for drilling thereafter.
Pending Vietnamese government approval of the recent farm-outs by Neon, the company's share of the seismic acquisition and processing commitment in both blocks will be fully funded by KrisEnergy and Enovation Resources.
Post farm-out approval, participants in both blocks will be Neon Energy (50%), KrisEnergy (40%) and Enovation Resources (10%).
