Geological features, hydrocarbon accumulation and deep water potential of East Indian basins

Post-drill geophysical characterization of two deep-water wells of Cauvery Basin, East Coast of India

“…in). The accumulation of hydrocarbon has been proven in the fractured basement and clastic sediments (mainly deep-water turbidite sandstone) of the Albian-Cretaceous age by public and private E&P companies (Qin et al 2017;Zhang et al 2019). The present study attempts a comprehensive analysis of the post-drill geophysical data of two exploratory wells drilled by Reliance Industries Limited (E&P) in the deep-water Cauvery Basin.…”

“…The deep-water hydrocarbon potential of East Indian passive margin sedimentary basins has been well-established in the last two decades (Qin et al 2017;Zhang et al 2019). The Krishna-Godavari (KG) and Cauvery Basin are considered Category-I basins having several producing fields and huge unlocked potential of hydrocarbon presence in their deepwater areas.…”

“…This rifting phase resulted in the formation of NE striking series of horst-graben structures (Fig. 1), which is indicative of extension and crustal stretching (Narasimha Chari et al 1995;Chand and Subrahmanyam 2001;Twinkle et al 2016;Qin et al 2017). These parallel trending subsurface highs are separating depressions from one another and extend into the offshore area (Fig.…”

“…During the postrift thermal subsidence (Late Cretaceous), regional unconformities were formed in almost all the eastern margin basins of India (Qin et al 2017). After the Late Cretaceous period, Cauvery Basin started growing in a shelfslope setting and subsequently matured as a passive margin basin (Sastri et al 1973;Chand and Subrahmanyam 2001).…”

Carboniferous Oceanic Basin Sediment-Gravity Flows in the Margin of the Junggar Basin, NW China: Characterisation and Implications for Hydrocarbon Potential and Evolution Pacing

“…During the last two decades, deep-sea exploration has discovered oil and gas in various parts of the world, including the Gulf of Mexico, West Africa (Cai et al ., 2016; Gee and Gawthorpe, 2006; Han et al ., 2012; Heiniö and Davies, 2007), the Campos Basin in Brazil (Ragagnin and Moraes, 2008), the UK North Sea (Dmitrieva et al ., 2012), the Nile Delta Basin (Samuel et al ., 2003), the Luwuma Basin in East Africa (Castelino, Reichert, and Jokat, 2017; Chen et al ., 2016), and the Bay of Bengal (Qin et al ., 2017; Ridd and Racey, 2015). Deep-sea oil and gas exploration in China has become increasingly common (Hu, Bao, and Hu, 2013), with discoveries in the Baiyun collapse, Pearl River Mouth Basin, South China Sea, Central Canyon Waterway, and Qiongdongnan Basin (Zhang et al ., 2017; Zhu, 2010).…”
