East Coast India has proven its potential with exploration successes from the Ganges Delta to Krishna-Godavari Basin, and has seen exploration in shallow and ultra-deep waters. The clear logic of discovering indigenous gas supplies close to the world’s fastest growing energy market that otherwise would be reliant on its native coal reserves has long been seen by exploration industry as critical in the human race’s journey to low carbon energy sustainability. Searcher is now leading the mission by seeking new understanding of the source and reservoirs on this outstanding margin.
Many global studies have now validated the technique of using seismic amplitude characteristics to not only identify hydrocarbon presence in reservoirs, but also to seek the source rocks they came from. Developed by studying the UK’s Kimmeridge Clay formation, this was a major de-risking tool in the validation of the source rock for the super-giant Venus-1 discovery in Namibia in 2022. This technology has proven application on modern reprocessed data and this will be directly applicable offshore East India.
Searcher’s Phase 1 reprocessing of 10,000km multi-vintage 2D seismic data, has commenced with Shearwater GeoServices in India. The modern broadband processing flow on this regional dataset is designed to focus on preserving amplitudes, increasing signal bandwidth and AVA/AVO friendly data improvements. Using the latest 2D denoise and demultiple algorithms, the new data has removed artefacts and significantly improves signal to noise of the key prospective intervals which when used on a regional scale allows us to hi-grade source kitchens and better constrain sedimentology of reservoir units.
This state of the art reprocessed regional 2D grid is a cost effective route to discovery of new giant hydrocarbons systems, which will be the focus for low carbon energy exploration in India over the coming decades. Searcher is lighting the road for the industry on this margin and revealing it to be one of the least explored prolific basins on Earth.
The East Coast India 2D Reprocessing final processed products will be available in Q4 2022.
