India Deep Focus – Investigating Sub-basalt Plays Through Integration of High-Resolution Geophysical Data
(1) Fugro, West Perth, WA, Australia.
India Deep Focus is a regionally focused integrated project designed to meet industry requests to deliver a regional play fairway analysis of the West coast of India. The India Deep Focus project is an initiative by Fugro to acquire 2D long offset seismic data on the West coast of India, from the Indus Fan in the North to the Mannar Basin in the South.
This project has been carried out in conjunction with the Directorate General of Hydrocarbons (DGH) of India. Innovative seismic processing has provided a dramatic increase in data quality to enable enhanced imaging beneath the Deccan basalts.
The West coast of India is generally regarded as under-explored and current understandings of the region are based on sub-optimal heritage information. The modern data contained within this project, present a fresh understanding and reveals new play concepts especially beneath the basalts.
The India Deep Focus dataset (IDF) consists of long offset, long record length 2D seismic data acquired and processed by Fugro along the west coast of India.
Modelling of high-resolution potential fields data acquired along with the seismic data has aided interpretation of the Deccan Trap basalts. Integration of the potential fields data, with available well data and analysis of regional palaeogeographic evolution based on the Fugro Robertson Plate Wizard™ project has resulted in a coherent understanding of the regional geological history and the identification of a potential deepwater sub-basalt hydrocarbon province.
Synthetic Aperture Radar data used has been used to interpret the presence of seeps and identify areas with an active petroleum system. The seeps identified as potential natural slicks occur beneath a significant syn-rift section and in some cases are associated with faults which were reactivated during the Tertiary. The presence of deep Mesozoic grabens offshore the Kerala-Konkan basin, and evidence of oil seeps, suggests that a previously unrecognized active petroleum system maybe present beneath the Deccan Trap basalts.
