Eni said July 24 that an exploration well in Block 114 in the Song Hong Basin offshore Vietnam has proven the presence of gas and condensate in the Ken Bau prospect.
Drilled to a depth of 3,606 m, exploration well Ken Bau 1X encountered several intervals of gas and condensate sandstone interbedded with Miocene age shale, with an estimated net reservoir thickness in excess of 100 m, Eni said in a news release.
Technical issues prompted the company to plug and abandon the well earlier than planned, but Eni said it believes “significant additional resources” could be found at deeper levels. The company said it plans to drill early next year to fully assess the upside.
Holding a 50% share, Eni Vietnam is the operator of the block. Partner ESSAR E&P holds the remaining 50%. Eni also operates neighboring Block 116.
Companies added three oil rigs in the week to Jan. 24, bringing the total count to 676, energy services firm Baker Hughes Co. said in its weekly report.
Most of the undiscovered technically recoverable oil resources are believed to be in the Brookian Sequence, the USGS report shows.
A Marcellus Shale discovery by EQT, Marathon’s Upper Three Forks completion and two horizontal Woodford producers top this week’s drilling activity highlights from around the world.
