India's Hydrocarbon Outlook – 2022-2023

105 DGH: 3 DECADES OF UNLOCKING INDIA'S HYDROCARBON POTENTIAL Figure 3.4: (a) Time slice at 5500 MS of 2D cubed volume of entire East Coast India (b) Zoomed-in slice of KG-Cauvery region (a) (b) Paleo-structural analysis and study of depositional environments have been carried out for older sedimentary units within Chhattisgarh basin to be published at upcoming 84th EAGE Annual Conference & Exhibition, 2023 to be held between 5-8 June 2023 in Vienna, Austria. 4) A statistical analysis to estimate the average rig time and easiness of drilling in the Indian Sedimentary Basins A statistical tool was developed to estimate the average rig time, easiness of drilling, and target depth, in the Indian Sedimentary Basins using data analytics. This statistical tool may help potential investors by providing a ready reference on the time and money required for drilling basin-wise which may assist them in decision making while bidding for any exploratory acreage and thereafter before venturing into any E&P project. The outcome of the paper will be presented at the Global Scientific Congress on Geology and Earth Science to be held on May 08-9, 2023 Dubai, UAE. Data rejuvenation, reprocessing and reorganization through Value-addition model of NDR: Under the provision of Article 3.7 of NDR Data Policy 2017, M/s TGS has carried out East Coast India 2D cubed seismic reprocessing project comprised of generating a set of 2D matched and merged migrations 2D cubed volumes. Through this project, M/s TGS has generated 570,000 Sq. km of seismic volume in East Coast India covering Cauvery, Krishna- Godavari (KG), Mahanadi and Bengal offshore basins. Total 250,000 LKM of Pre-Processed 2D seismic data were used to generate 2D cubed volume. For this project, M/s TGS used ‘2Dcubed’ algorithm, represents a new interpolation technique, which provides a 3D seismic volume based on relatively dense 2D seismic grids. This 2D cubed volume is suitable for regional interpretation over the all East Coast sedimentary basins.
