NELP VII SAR Seep Study
Fig 1: NPA’s Circum India Coverage;
NELP 7 blocks in white, red = compliant NPA
coverage.
Rationale
Besides the continued success of further major gas discoveries,
the most significant offshore development in 2007 was the
first commercial Cretaceous oil discovery made by Reliance
in the Krishna-Godavari Basin plus an oil discovery in the
Cauvery Basin. The release of a further 38 new blocks in the
NELP 7 round, comprising 9 shallow-water and 29 deep-water
blocks, has now provided the industry with the potential for
further offshore oil discoveries.
Seep detection by SAR (Synthetic Aperture Radar) is a proven
technique for mapping surface oil seeps which could provide
the first indication of (black oil) petroleum systems in these
blocks.
NPA’s NELP VII study (Fig 1) will provide a minimum
of dual coverage over all blocks, and will include the addition
of more than 100 new interpreted scenes and establish which
blocks contain seepage slicks. All data will be provided in
ArcGIS format with all SAR scenes and seepage slicks hyperlinked
to display geographically.
Components of NPA India
Study (including NELP VII blocks)
- A total of 697 NPA SAR scenes with minimal dual coverage;
additional coverage to cover NELP VII blocks has now been
acquired.
- More than 6,494 slicks mapped, including more than 415
higher confidence seepage slicks, indicating presence of
oil petroleum systems in certain basins.
- Slick density and slick repeat data.
- Fully digital data available in modular USID format for
large or small areas.
Cost
Dependent on volume, with NPA archive data at discounted rates.
