Volcanic facies architecture of early bimodal volcanism of the NW Deccan Traps: Volcanic reservoirs of the Raageshwari Deep Gas Field, Barmer Basin, India

“…The thickness of the volcanic pile, the physical properties of different volcanic facies and the transition of volcanic facies into the underlying and overlying strata have a cumulative effect on the imaging potential of both intra‐ and sub‐basalt geology (e.g. Millett, Manton, et al., 2020). However, given firstly the significantly variable thickness of the Prithvi Member due to erosion, and secondly the amplitude and continuity of the Top Pre‐volcanic (PV) Mesozoic reflector, the difference in seismic character above and below the A1 horizon is interpreted as a genuine lithological response, rather than a reduction in seismic resolution with depth.…”

“…The RDG Field represents a key global example of a volcanic hosted reservoir (Chowdhury et al., 2014; Dolson et al., 2015), and as with other volcanic rifted margin associated sequences, evolved in association with sedimentary depo‐centres which have resulted in the discovery and development of important hydrocarbon resources (e.g. Dolson et al., 2015; Jerram et al., 1999; Millett et al., 2020; Senger et al., 2017; Vijayan et al., 2016). Detailed analyses of the RDG volcanic sequence is undertaken utilizing core, wireline, petrophysical and 3D seismic data analyses from four key wells in the field.…”

Discovery of Two Sub‐Volcanic Basins Below the North Atlantic Igneous Province (NAIP), Faroe Platform, NE Atlantic Ocean

“…This number correlates well with the maximum known original FIBG thickness, which was established on southern part of Suðuroy-at Lopra-1/1A well location-and estimated to be c. 4.4 km (Ólavsdóttir et al, 2019). Newly published work from the Vøring and Møre areas reveal the thickness of the volcanic landward flows are c. 3-4 km thick (Abdelmalak, Meyer, et al, 2016;Millett et al, 2020) which is comparable with the landward flows on the Faroe Platform. The estimated thickness of the volcanic package is obviously influenced by the chosen density of the rocks (Figures 4-7 & Table 1); the gravity data used in this study is based on published data and from the density log information in the wells drilled in the Faroese and surrounding areas, and display a range for the volcanic rocks from 2.41 to 2.87 g/cm 3 (Table 1).…”
