The Deepsea Metro 1, under contract to BG Group and Ophir Energy, tapped into a reservoir containing an estimated 1.03 trillion cubic feet (tcf) of natural gas according to a statement today by Ophir Energy.  For BG Group (80%) and Ophir Energy (20%), this marks an astonishing 16th consecutive discovery well in Blocks 1, 3 and 4.

The Gusto P10000 drillship, under management by Odfjell Drilling was operating in waters 1,379 meters deep and drilled to a depth of 3,969 meters when it encountered an 18 meter gas column in the Fulusi prospect.  From there, the rig drilled a sidetrack well and encountered another gas column of 140 meters in good quality reservoir sands within the adjacent Kamba prospect.

This discovery, plus recent volume updates on the earlier discoveries, increases Ophir’s estimate of the total Block 1, 3 and 4 mean (2C) recoverable resource to 17.1 TCF.

Ophir Energy says the Kamba-1 result provides critical mass for an LNG train to be supplied from the fields in Block 4 and also takes the overall resource volume to the threshold for a future potential third LNG train to be from Blocks 1 and 4.

The Deepsea Metro I drillship will remain in Tanzania and now moves to drill two operated wells for Ophir in the East Pande and Block
7 PSCs.
