Australia’s Santos yesterday reported a gas discovery offshore Bangladesh, explaining that Sangu-11 has penetrated a new gas reservoir in the Sangu area with approximately 20 metres of good quality gas pay.
The well will be completed and tied into the Sangu facilities and will provide incremental gas to Chittagong in the coming months once marketing arrangements have been finalised.
Work is continuing to assess volumes and flow potential of the reservoir. After completion of Sangu-11, the Seadrill jack-up drilling rig Offshore Resolute will be demobilised.
Sangu-11 was the third well of a three-well drilling campaign in Block 16 PSC that commenced in September 2011. The first well, South Sangu-4, found gas in one target but was unable to add further reserves due to encountering anomalously high formation pressure, and had to be abandoned prior to reaching its primary objective. The second well, NE Sangu-1, drilled in December 2011, failed to encounter commercial hydrocarbons and was also abandoned.
John Chambers, President of Santos in Bangladesh, said: “We are pleased to have found new volumes of gas that can supply the Chittagong market. Further gas discoveries will still be needed to supply the market in the medium to long term. The mixed success of this program is a reminder of the risks and challenges associated with gas exploration and appraisal, and underlines the importance of providing the right investment framework to encourage further exploration in the Bay of Bengal.”
