Italian oil major Eni has contracted Vietnamese offshore drilling company PV Drilling’s jack-up rig PV Drilling VI for its upcoming drilling campaign offshore Vietnam.

The drilling programme, the details of which were not divulged, is scheduled to start this month.

No dayrate was revealed for the charter although Oslo-based rig brokerage, advisory and project development company Bassoe Offshore reportedly estimates the dayrate to be around $65,000 with the contract expected to last until April.

PV Drilling will also provide other technical services including directional drilling and surveying and oil spill response.

Eni last year drilled the Ken Bau-2X well on Block 114 in the Song Hong Basin offshore Vietnam, which confirmed a significant hydrocarbon accumulation on the 2019 Ken Bau discovery.

Swift route

Preliminary estimates of the Ken Bau accumulation are between 7 trillion and 9 trillion cubic feet of raw gas in place with 400 million to 500 million barrels of associated condensate.

Eni last July said it and partner Essar were making efforts to “swiftly appraise Ken Bau despite the significant operational challenges posed by the Covid-19 pandemic”.

Eni Vietnam operates Block 114 on behalf of equal co-venturer Essar.

The Italian operator also has plans for new drilling and seismic acquisition in the Song Hong basin, where it also has 100% equity of neighbouring Block 116.

The 2015-built PV Drilling VI jack-up, constructed by Keppel, can operate in water depths of up to 121 metres and drill to a maximum sub-surface depth of 9000 metres.
