Woodside confirms successful Shwee Yee Htun-2 appraisal well offshore Myanmar

Woodside has announced that the Shwe Yee Htun-2 appraisal well in Block A-6, located offshore Myanmar, has successfully appraised the 2016 Shwe Yee Htun-1 discovery.

The Shwe Yee Htun-2 appraisal well was drilled down-dip from the Shwe Yee Htun-1 well and intersected a gross gas column of 168 m (measured depth rotary table (MDRT)) (143 m true vertical thickness).

A total of 41 m of net pay (true vertical thickness) has been interpreted within a high quality-reservoir. The gas column has been confirmed through wireline logging and pressure measurements, which have also demonstrated that the intersected reservoir is highly likely to be in pressure communication with the Shwe Yee Htun-1 discovery, which is approximately 10 km east of the current drilling location. The minimum total gross gas column based on wireline pressure data from both wells is now estimated to be approximately 237 m.

The Shwe Yee Htun-2 well was spudded on 20 July 2018 and reached a total depth of 4820 m (MDRT) in the main well bore. The well was subsequently sidetracked and drilled to a total depth of 4850 m (MDRT), which enabled the successful acquisition of conventional core, additional wireline logs and completion of a drill stem test. These tests have confirmed good reservoir quality, permeability and well production deliverability.

The drill stem test was performed across a 35 m section of the reservoir and flowed at ~53 mmscf/d on a 40/64” choke over 80 hours. The well will be plugged and abandoned as planned.

Woodside CEO Peter Coleman said the initial results from the Shwe Yee Htun-2 well were positive and helped to build Woodside’s knowledge of the resources in Block A-6.

“The well has encountered good quality reservoir, with a gas column at the high-end of our pre-drill estimates. We look forward to completing detailed analysis of the well results.

“The results are encouraging and we hope that the resources in the permit can contribute energy that will support Myanmar’s future economic development,” he said.

Woodside Energy (Myanmar) Pte Ltd holds a 40% stake in Block A-6 and is the joint operator of the block and operator of the Shwe Yee Htun-2 well. MPRL E&P Pte Ltd, with a 20% interest, is joint operator of Block A-6. Total E&P Myanmar holds the remaining 40% interest in the block.
