Good start for Woodside off Myanmar

First well in multi-well programme is a success for Australian independent

Woodside Petroleum has confirmed the success of its first appraisal well on the Thalin deep-water gas discovery off Myanmar, and has an added a fifth firm well to its current drilling programme.

The company spudded the Thalin-1B appraisal well in late February using the drillship Dhirubhai Deepwater KG2 to start a four-well plus three contingent campaign.

There was 99 metres of core recovered over the objective reservoir interval, and the lower section flowed at a sustained rate of 50 million cubic feet per day over a 50-hour period amid "excellent reservoir quality".

Flow testing of the upper reservoir will follow.

The Thalin-1B well will be followed by the Thalin-2 appraisal well also in Block AD-7.

The company has also added a fifth firm drilling target.

“In Myanmar, our interpretation of seismic data has identified an additional low-cost exploration target with upside potential in Block A-6, which contains the Shwe Yee Htun-1 discovery. This increases our Myanmar firm well schedule for 2017 to five," said chief executive Peter Coleman.

Woodside operates Block AD-7, where water depths are between 800 and 1300 metres, with a 40% stake and its sole partner is Posco Daewoo with a 60% interest.

In Block A-6, Woodside holds 40% while its partners are MPRL E&P) (20%) and Total (40%).
