Results of the Buffalo-10 oil appraisal well offshore Timor-Leste are inconclusive, with the joint venture reporting a small oil discovery but with unresolved issues.

The operator Carnarvon Energy said the well was drilled to a total depth of 3415 metres in an 8.5-inch hole section.

Observations from logging while drilling tools have identified the primary reservoir has been intersected, with indications of hydrocarbons as anticipated in the Elang formation.
