British oil company Salamander Energy said that the Dambus-1 exploration well in the Kutai PSC, offshore Indonesia, has been plugged and abandoned after seeing hydrocarbons in volumes thought to be sub-commercial.
The Dambus-1 exploration well, operated by Serica Energy was spudded on 4 September 2010 to investigate a stacked sequence of Miocene reservoir sands.
The well was initially drilled as a deviated well to a TD of 3,225m and encountered hydrocarbons in the gross interval 2,070-2,110m with indications of further hydrocarbons below 2,760m.
A sidetrack Dambus-1ST was drilled to TD of 2,800m to allow an extensive program of logging and sampling to be completed.
The company said that excellent quality gas-bearing sands were logged in the interval 2,025-2045m, together with oil shows, and the pressures were evaluated.
Following assessment, the discovery was deemed to be sub-commercial and the well has been plugged and abandoned.
The Trident drilling rig will now move to drill the Marindan exploration well, at the southern end of the Kutai PSC.
Salamander Energy has a 23.4% interest in the Kutai PSC.
