ENI Discovers Gas Reserves In Vietnam’s Oil Well
BY TAYO ELEGBEDE
Eni has confirmed that its exploration well, Ken Bau-2X, located in Block 114, Song Hong Basin, offshore Vietnam, has a significant hydrocarbon accumulation on the Ken Bau discovery, further expanding its potential.
According to the company, Ken Bau 2X was drilled 2km apart from the discovery well in 95 m of water depth till a total depth of 3658m below sea level and encountered a pay in excess of 110m in several intervals of Miocene sandstones interbedded with shale.
The company noted that preliminary estimates of Ken Bau accumulation provide a range between 7 and 9 trillion cubic feet (Tcf) of raw gas in place with 400 – 500 million barrels (Mbbl) of associated condensates, and that the well will now be plugged and abandoned.
This development has occurred barely a year after they made public discovery of proven presence of gas and condensate in it’s exploration well, located in block 114, Song Hong Basin, offshore Vietnam in the Ken Bau prospect.
Ken Bau 1X well was plugged and abandoned ahead of the original plan due to technical issues, prior to reaching deeper levels that could hold significant additional resources.
And obviously their plans on a drilling campaign early this year
to fully assess the substantial upside of the discovery has been realised with this new development.
“Two mini drill stem tests (DST) were conducted, coupled with an extensive data acquisition campaign comprising fluid sampling,” the company stated.
They also remarked that despite significant operational challenges posed by the COVID-19 pandemic since early this year, Eni Vietnam’s and its partner Essar Exploration and Production’s efforts to swiftly appraise the full extent of the accumulation was in course, adding that Ken Bau 2X results confirm the importance of the discovery made in 2019.
Eni Vietnam is the Operator of Block 114 with a 50% share, while Essar E and P holds the remaining 50%.
Eni Vietnam with its partner is currently planning additional drilling and testing on Ken Bau discovery coupled with new drilling and seismic activity in the Song Hong basin, where Eni operates with a 100% share the neighbouring Block 116.
The gas market in Vietnam according to them is rapidly growing, which is driven by the Country’s consistent Gross Domestic Product (GDP) progression and consequent development of gas-to-power plants supplied by domestic resources and, in the future, imported Liquified Natural Gas (LNG).
Therefore Ken Bau discovery will potentially provide a fast-track solution to meet the increasing energy demand of that market.
Eni has been in Vietnam since 2013, and currently operates four blocks all located in the underexplored Song Hong and Phu Khanh basins, offshore central Vietnam
