Characteristic latest Neoproterozoic and Early Paleozoic acritarchs and associated organic-walled microfossils are recorded from the sediments of Marwar Supergroup encountered in BGW-A well (Bikaner-Nagaur Basin) from 1123-481 m depth. Six distinct acritarch assemblages, broadly comparable with globally known Ediacaran (Vendian) and Cambrian assemblages are recognised. The recovered microfossils provide precise age for different units of the Marwar Supergroup whose ages, till now, were poorly understood due to absence or paucity of invertebrate and other mega and microfossils. Jodhpur Group (1123-1105 m), the basal unit of Marwar Supergroup, records abundant ornamented sphaeromorphs (Lophosphaeridium spp.) alongwith various species of Leiosphaeridia, suggesting Late Ediacaran age. Occurrence of small micrhystrids (Asteridium spp.) and appearance of Dictyotidium birvetense, Pterospermella solida and Annulum squamaceum in lower part of Bilara Group (1105-1081 m), suggests latest Ediacaran to early Early Cambrian age. Hanseran Evaporite Group (1068-907m) is marked by abundant Retisphaeridium dichamerum, Dictyotidium birvetense, Cristallinium cambriense, Comasphaeridium sp. cf. C. strigosum and Archaeodiscina umbonulata indicating late Early Cambrian to early Middle Cambrian age. Microfossil contents in Nagaur Group (907-727m) are very poor. The succeeding Upper Carbonate Sequence (727-481 m) shows abundant Cristallinium randomense, Cymatiosphaera crameri and Asteridium spp., along with other species of Cymatiosphaera and Cristallinium, and also includes the early Late Cambrian marker forms, such as Striatotheca loculifera and Dorsenidium (Veryhachium) minutum that suggest late Middle Cambrian to early Late Cambrian age. The recorded acritarch assemblages suggest Late Ediacaran to early Late Cambrian (ca 570-500 Ma) age for the Marwar Supergroup, with demarcation of Precambrian-Cambrian boundary within the lower part of Bilara Group. Associated microfossils indicate intertidal/foreshore depositional environment for Jodhpur and Nagaur groups, whereas inner neritic to subtidal for the Bilara, Hanseran and Upper Carbonate units. Occurrence of an Early Permian palynoflora in the succeeding sequence (481-427 m depth) indicates a major hiatus of ca 200Ma between the Marwar and overlying Bap/Badhaura sequences which involves the absence of middle Late Cambrian to Late Carboniferous sediments in this basin. Latest biostratigraphic data from Ujhani (Ganga Basin) and Bhander (Vindhyan Basin) sediments suggest that the above two sequences are closely comparable with the Marwar Supergroup, and show the prospective exploration challenges as do the Marwar Supergroup. © GEOL.

New constraints on pressures and temperatures experienced by rocks of the Himachal Himalaya are presented in order to test models for the emplacement of the Himalayan crystalline core here. A variety of methods were employed: petrographic analysis referenced to a petrogenetic grid, exchange and net-transfer thermobarometry, Ti-in-biotite thermometry, and analysis of quartz recrystallization textures. Rocks along three transects (the northern Beas, Pabbar, and southern Beas transects) were investigated. Results reveal spatially coherent metamorphic field gradients across amphibolite-grade and migmatitic metamorphic rocks. Along the northern Beas transect, rocks record peak temperatures of ∼650-780°C at low elevations to the north of ∼32°10' N; rocks in other structural positions along this transect record peak temperatures of <640°C that decrease with increasing structural elevation. Rocks of the Pabbar transect dominantly record ∼650-700°C peak temperatures to the east of ∼77°55' E and ∼450-620°C peak temperatures farther west. Peak temperatures of ∼450-600°C along the southern Beas transect record a right-way-up metamorphic field gradient. Results are integrated with literature data to determine a metamorphic isograd map of the Himachal Himalaya. This map is compared to metamorphic isograd map pattern predictions of different models for Himalayan crystalline core emplacement. This analysis excludes models involving large magnitude (>20-30 km) extrusion and permits (1) models involving small magnitude (<20-30 km) extrusion that is discontinuous along the orogen and (2) tectonic wedging models, in which the crystalline core was emplaced at depth between a sole thrust and a back thrust in the Early-Middle Miocene. © 2013.

The burgeoning oil and gas consumption in India in recent years has necessitated looking into the Proterozoic basins of India, which are sparsely explored and have a scanty knowledge base. The rationale for hydrocarbon exploration in Indian Proterozoic basins is derived from the fact that they have large basinal areas, wide geographical distribution, varied geotectonic setting and sedimentary fill. The favourable tectonic settings of these basins, pronounced biological activity, known hydrocarbon gas seepages, and subsurface commercially viable oil and gas shows in the Bikaner-Nagaur and Vindhyan basins and analogous basins throughout the world necessitate proactive exploration strategies in these basins. The basins of Bikaner-Nagaur, Vindhyan, Cuddapah and Chhatishgarh include thick Neoproterozoic/basal Lower Palaeozoic (Cambrian) successions, in addition to Palaeoproterozoic and Mesoproterozoic sequences. The Neoproterozic sediments in these basins incorporate thick successions of shale, limestone and sandstone. These successions have rich organic matter of high-quality cyanophycean (stromatolites, acritarchs and filamentous algae) affinity that is proven to be high-quality (type one) source material for hydrocarbon generation and also involved in later structurization. However, the Neoproterozoic sedimentary pack in the Bhima-Kaladgi basins is comparatively less thick, and appears to have less prospectivity. The available geological and source-rock data are reassessed for their hydrocarbon prospectivity in order to help in planning a strategy for exploration in these basins. © The Geological Society of London 2012.

Indian oil industry has come a long way since the first oil discovery at Digboi in 1889 through concerted exploratory efforts. Production of oil from a 5 barrels per day level from a single field in Assam has grown to more than 750000 barrels per day from over 50 major oil and gas in seven sedimentary Basins and is projected to attain 1 million barrels per day mark in near future. After Independence, oil and gas exploration was accorded high priority and was taken up by National, Private and International oil companies across the 26 sedimentary Basins covering an area of about 3.14 million sq. kms. Of the 26 sedimentary Basins, 7 Basins are producing oil and gas today. Sedimentary Basins of India are categorised into four categories based on their degree of hydrocarbon prospectivity as presently known. At present India's estimated hydrocarbon resource is of the order of 28 billion tonnes of oil equivalent (BTOE) and an Initial In-place volume of about 11.18 billion tonnes of oil equivalent (BTOE). A project for re-assessment of the resource potential of Indian Sedimentary Basins has been initiated by Government of India with active participation of ONGC, OIL and DGH in view of extensive availability of new data from all the Sedimentary Basins. Currentefforts are to enhance the production from category-I Basins with a focus on upgrading the Category-II Basins to Category-I Basins. Present paper outlines the endeavours during last few years through opening up of new areas, especially frontier areas of Proterozoic Basins of Vindhyan and Satpura, Deep offshore Basins of Bay of Bengal and Arabian Sea within Indian exclusive economic zone, Andaman fore-arc and back-arc Basins, unconventional sources of hydrocarbons such as Basement exploration, CBM (Coal Bed Methane), shale oil and gas, gas hydrates and leveraging the technology advances in Petroleum exploration. © 2016 Printed in India.

Gas hydrate was discovered in the Krishna-Godavari (KG) Basin during the India National Gas Hydrate Program (NGHP) Expedition 1 at Site NGHP-01-10 within a fractured clay-dominated sedimentary system. Logging-while-drilling (LWD), coring, and wire-line logging confirmed gas hydrate dominantly in fractures at four borehole sites spanning a 500m transect. Three-dimensional (3D) seismic data were subsequently used to image the fractured system and explain the occurrence of gas hydrate associated with the fractures. A system of two fault-sets was identified, part of a typical passive margin tectonic setting. The LWD-derived fracture network at Hole NGHP-01-10A is to some extent seen in the seismic data and was mapped using seismic coherency attributes. The fractured system around Site NGHP-01-10 extends over a triangular-shaped area of ~2.5 km2 defined using seismic attributes of the seafloor reflection, as well as " seismic sweetness" at the base of the gas hydrate occurrence zone. The triangular shaped area is also showing a polygonal (nearly hexagonal) fault pattern, distinct from other more rectangular fault patterns observed in the study area. The occurrence of gas hydrate at Site NGHP-01-10 is the result of a specific combination of tectonic fault orientations and the abundance of free gas migration from a deeper gas source. The triangular-shaped area of enriched gas hydrate occurrence is bound by two faults acting as migration conduits. Additionally, the fault-associated sediment deformation provides a possible migration pathway for the free gas from the deeper gas source into the gas hydrate stability zone. It is proposed that there are additional locations in the KG Basin with possible gas hydrate accumulation of similar tectonic conditions, and one such location was identified from the 3D seismic data ~6 km NW of Site NGHP-01-10. © 2010.

Novel switching sequences have been proposed recently for a neutral-point-clamped three-level inverter, controlled effectively as an equivalent two-level inverter. It is shown that the four novel sequences can be grouped into two pairs of sequences. Using each pair of sequences, a hybrid pulsewidth modulation (PWM) technique is proposed, which deploys the two sequences in appropriate spatial regions to reduce the current ripple. Further, a third hybrid PWM technique is proposed which uses all the five sequences (including the conventional sequence) in appropriate spatial regions. Each proposed hybrid PWM is shown, both analytically and experimentally, to outperform its constituent PWM methods in terms of harmonic distortion. In particular, the third proposed hybrid PWM reduces the total harmonic distortion considerably at low- and high-speed ranges of a constant volts-per-hertz induction motor drive, compared to centered space vector PWM. © 2013 IEEE.

A high-amplitude anomaly was identified in the Upper Oligocene Daman Formation clastic sequence during initial interpretation of newly acquired 3D seismic data in the Tapti-Daman sub-basin offshore western India. This anomaly exhibited the depositional signature of a channel and was interpreted as bright spots associated with gas sands, consistent with the occurrence of thin gas pays in the sandstone reservoirs of Daman Formation in the area. Considering thickness and areal extent, thick gas sands were predicted, upon drilling; however, thick water-bearing sands were found. The predrill interpretation was mainly based on windowed amplitudes without validation through character of reflection events and other supporting evidence such as frequency, velocity, and AVO. © 2010 Society of Exploration Geophysicists.
