HOUSTON -- ION Geophysical Corp. has acquired an additional 6,200 km (3,852 mi) of regional seismic data offshore India's western coast as part of its ongoing IndiaSPAN program. Another 3,800 km (2,361 mi) is currently being acquired off the east coast of the country. The additional data from the west coast, now being processed by ION's GX Technology (GXT) subsidiary using the latest pre-stack time (PreSTM) and depth migration (PreSDM) techniques, will be available prior to the eighth round of the New Exploration and Licensing Policy (NELP VIII) later this year.

NELP VIII is expected to offer seventy new offshore blocks covering approximately 163,500 sq km (63,128 sq mi). IndiaSPAN is a basin-scale seismic program designed to provide a comprehensive regional understanding of the petroleum systems offshore the east and west coasts of India.

IndiaSPAN II West was designed to image through the Deccan Basalts offshore west India using a deep-tow methodology for better signal penetration and improved imaging resolution beneath the basalts in the area. The program should further develop and validate concepts generated from IndiaSPAN I, including the presence of a thick Cretaceous-Jurassic sediment section and the identification of extensive, compressional rift-related structures underneath the basalts, the company says.

IndiaSPAN II East is intended to validate the new play concepts that emerged from the IndiaSPAN I program. Key areas of focus include the ultra-deep coastal graben in the East Coast along with the E-85 ridge, Cauvery basin, and the possible salt basin in the Gulf of Mannar.
