Natural gas leak at Indonesian feed block

LNG Industry,

Inpex Corporation announced on Friday that a shallow gas release occurred on the development well on the Tunu field lying in the offshore Mahakam Block, located in East Kalimantan, Indonesia on Friday 8th November 2013.

The Mahakam block is a centre for the production of crude oil and natural gas. It represents the largest producer of natural gas in the country with an output of 1.7 billion ft3/d. Natural gas is supplied to the Bontang LNG liquefaction plant before being shipped as LNG to Japan.

According to the project operator Total E&P Inodonesie (Total), on 8 November a shallow gas release occurred on well TN-C414, operated by Total and being drilled using Raissa rig on the Tunu field in Anggana Sub-District, Kutai Kartanegara District, East Kalimantan Province, Indonesia. The gas being released is coming from ‘shallow gas’ consisting of a natural gas pocket contained in a geological formation located very close to the surface, with no evidence of liquids.

No injuries

There are no injuries reported and all onboard personnel were safely evacuated from the rig to neighboring accommodation facilities. The shallow gas release incident is being closely monitored and no fire has been declared. The area is fully secured by observation vessels. At this stage, based on an aerial survey, there is no evidence of oil spill around the area.

Total is currently deploying the necessary resources to mitigate this incident, which was reported to the relevant authorities.

So far the incident has had no major impact on the gas production of the Mahakam Block.
