Block B Joint Venture, operated by TotalFinaElf (operator, 37.5%), has made a significant gas and condensate discovery in offshore Block B in Brunei Darussalam. The block is located approximately 50 kilometres north of the capital, Bandar Seri Begawan.

The discovery confirms the potential of the deep horizons of Block B. It was made at a vertical depth of around 4,400 metres, below the currently producing gas and condensate reservoirs of the Maharaja Lela Jamalulalam field. Well MLJ1-06 struck a column of hydrocarbons of around 100 metres.

TotalFinaElf is associated in Block B with Shell (35%) and local partners (27.5%). TotalFinaElf has also been selected for Brunei's very deep offshore Block J.
