Myanmar seepage studySeepage detection by SAR (Synthetic Aperture Radar) is a proven technique for identifying active offshore oil seeps.

Myanmars Ministry of Energy have been offering both shallow and deepwater blocks since their original release in 2013. NPA have been undertaking a major upgrade of their seepage survey for this region.

The study now contains:

Over 550 weather-compliant and interpreted satellite SAR scenes

Over 1000 slicks, including possible seepage slicks and temporal repeats

BackgroundOnshore Myanmar has a long history of oil and gas discoveries, which stretches back to the 19th century, with the first onshore oil discovery in 1887.

Offshore, giant gas discoveries at Yadana (1983) and Yetagan (1992) extended this play-fairway offshore and the more recent discoveries at Schwe (2004) and Zawtika (2007) have been encouraging.

However, apart from associated condensate in Yetagan and other smaller fields, the evidence for a viable black oil play remains elusive and the study directly addresses this.

Myanmar 2015 seepage studyAs a world-leading satellite remote sensing service provider, NPA Satellite Mapping (NPA) detect, interpret, classify and monitor natural seepage and pollution slicks occurring in offshore environments.
