The rig is currently in transit to the offshore location in 30 m (98.4 ft) of water in the Timor Sea in the TL-SO-T 19-14 production sharing contract. In a problem-free case, the well could take around 35 days to drill.
If successful, the well will be suspended with an unperforated liner, and cemented across the reservoir for re-entry and completion for production at a future date.
In 2016 Carnarvon acquired the permit containing the Buffalo field, which was shut down by previous operator BHP.
Reprocessing of the 3D seismic dataset using modern full waveform inversion (FWI) technology suggests the presence of an attic oil accumulation remaining after the original development.
The well will test the extent of this accumulation while drilling through the Elang reservoir in the 8-½-in. hole section, where Carnarvon expects to penetrate both the existing oil column and assess the extent of the attic column.
Carnarvon will assess information on the height of the attic and reservoir/fluid properties, acquired during drilling, following completion of the well operation.
