Abstract

The Andaman Sea Basin, India has proven hydrocarbon potential. Positive indicators have been seen on the reprocessed seismic data: reservoir, source, maturity, migration, seal and trapping geometries. The top and base of proven limestone reservoir horizon can be directly mapped from the reprocessed seismic. Trapping geometries have been seen in many different locations in a number of different plays, both structural and stratigraphic, in limestone as well as clastic intervals. Positive indicator show thermogenic in addition to biogenic gas source intervals may be present. Bright and flat spots, gas clouds and chimneys and Bottom Shadowing Reflectors (BSR's indicative of gas hydrates) have been seen on the reprocessed seismic data at many different locations within the project area which imply generation and migration of hydrocarbons. Prospective trends have been observed in and can be extrapolated into both unlicensed and NELP IX acreage. Reprocessed seismic data is available immediately as PSTM & PSDM versions in SEG-Y format; within acreage on offer in the current Indian Licence Round (NELP-IX).
