Harbour hits gas off Indonesia
Harbour Energy has completed drilling at the Timpan-1 exploration well off the coast of Indonesia's North Sumatra region, the London-listed independent said on July 11, tapping into a material gas accumulation in a result that the company said was encouraging.
Harbour that the well flowed back 27mn ft3/day of natural gas during testing, in addition to 1,884 barrels of oil/day of associated API condensate. Further work will need to be carried out before Harbour decides if the discovery is commercial. The well was drilled to a total vertical depth of 13,818 ft subsea, and encountered a 390-ft gross gas column in fine-grained sandstone reservoir.

Timpan-1 is situated in the Andaman II offshore production area. Harbour Energy operates the licence with 40% equity interest, working in partnership with BP (30%) and Mubadala (30%). Timpan-1 is the first well to be drilled in the production area by the current Andaman II consortium.
Harbour Energy also owns 50% operated interest in the Tuna offshore block, situated close to the Indonesian-Vietnam maritime border. Tuna contains an estimated 100mn barrels of oil equivalent, of which 55% is expected to be gas. First production at Tuna is expected in 2026.
In Indonesia's producing Natuna Sea Block A asset, Harbour Energy currently has a 28.67% operated stake. The licence is a major supplier of gas to Singapore, comprising seven producing fields connected to Singaporean markets via the West Natuna Transportation System.
Gary Selbie, Harbour Energy president director for Indonesia, said: "We are encouraged by the result of this play-opening exploration well.
"We look forward to working with our partners and the government of Indonesia to determine the potential for commercialisation of this important discovery.”
