Deccan Trap Basement: Evolution and Processes

Om Prakash Pandey om_pandey@rediffmail.com

(India)


J P Shrivastava

(India)


Dr. O.P. Pandey, borne on May 12, 1950 is an internationally known scientist, who graduated from Indian School of Mines, Dhanbad and Victoria University of Wellington, New Zealand. He has worked extensively on multidisciplinary geoscientific subjects like, terrestrial heat flow, lithosphere structure, geophysical, geological, and geochemical and geodynamic evolution of continents, catastrophic events, seism genesis, global volcanism and earth resources development. His innovative contributions are highly recognised by national and international researchers. He is fellow of several geoscientific societies


Prof. J. P. Shrivastava, borne on 22nd June, 1955 and graduated from university of Saugar, is an international authority on origin and evolution of Deccan Volcanic Province. His research interests include petrology and geochemistry. He has published around 150 research papers on such topics. His innovative contributions are globally well recognised. Currently, he is holding a position of professor at the department of geology, University of Delhi. He has won several prestigious awards in geosciences

Deccan Traps, Geological evolution, Crystalline basement, Geodynamics, Peninsular India.

The Indian shield is known to have been quite active, having undergone several cycles of degeneration and restructuring of underlying lithosphere during the entire course of geologic history, thus differs considerably from other stable areas of the Earth. It has been one of the most mobile continents on surface of the Earth since its breakup from the Gondwanaland, during which, it has witnessed several rifting and continental breakup episodes, multiple plume interactions, K-T boundary bolide impact and massive intra-plate volcanism (e. g. Deccan and Rajmahal Traps). Out of these two volcanic eruptions, Deccan Traps are considered as one of the largest eruptions on the surface, covering 0.51 × 106 km2 area in the west and central India. Its eruption coincided with the K-T boundary biological mass extinction, perhaps the most violent in the Earth’s geological history. Besides, this terrain remains highly earthquake prone, having witnessed large number of damaging earthquakes in the recent past, such as 1967 Koyna, 1993 Killari, 1997 Jabalpur and 2001 Bhuj.

In spite of several geological, geophysical and seismotectonic investigations, the nature of the crystalline basement concealed below the thick volcanic cover however, seems to be studied least. Insignificant information is available that too is primarily based on the scanty seismological investigations or from the rocks exposed close to its periphery. To understand thoroughly, physical, compositional and thermo-geodynamical nature of the underlying Neoarchean crust which lie below the Deccan Traps, has become a major challenge for geoscientific community. The objective of this workshop is therefore, to invite innovative contributions based on multi-parametric geological, geochemical, mineralogical and geophysical investigations, to understand evolutionary nature of the crystalline basement and underlying mantle processes that may provide a new insight into the crustal evolution, particularly of this segment of the Peninsular shield.

Carbon Capture and Utilization as a Pathway to Reliable Storage


Jennifer Wilcox jlwilcox@wpi.edu (USA)


Jennifer Wilcox is the James H. Manning Chaired Professor of Chemical Engineering at Worcester Polytechnic Institute, USA. Jennifer Wilcox works on ways to test and measure methods of trace metal and carbon capture, to mitigate the effects of fossil fuels on our planet.

Prof. Wilcox has previously worked at Colorado School of Mines and Stanford University.

CO2 capture, utilization, storage, economic incentives of CCUS

It is well-known that CO2 utilization does not scale in regards to both magnitude and time of carbon storage required to positively impact climate. However, since utilization of CO2 most often requires high-purity CO2 as a feedstock, purification of CO2 from a dilute stream (e.g., air, industrial sources, natural gas or coal-fired power plant exhaust streams) is a required component of the utilization pathway. This purification step, whether it involves concentrating CO2 from air or a more concentrated point source, will be a required step for both utilization and geologic storage. Due to the lack of economic incentive today to inject and permanently store CO2 underground, utilization provides a pathway toward the generation of a carbon market. Research that focuses on the broad range of CO2 utlliization opportunities is of interest as the promising technologies will lead to demonstration-scale projects and public acceptance of displacing natural CO2 with anthropogenic CO2. Increasing demonstration-scale projects for utilization will inevitably lead to a decrease in the cost of the purification step, which will directly lead to reduced costs for conventional carbon capture with subsequent reliable storage. Hence, in the absence of adequate economic incentive to capture and permanently store CO2, utilization is a necessary intermediate step.

CO2 trapping; Coupling process; geological CO2 sequestration; energy geoscience; reservoir engineering

The mitigation of carbon dioxide (CO2) emissions has become one of big issues in the world. Subsurface storage and utilization of captured anthropogenic CO2 (CCUS) provides a promising technology to decrease the rate of increase of CO2 in the atmosphere. The CCUS is characterized as an interdisciplinary R&D technology in energy geosciences between the basic science (geology, geophysics and geochemistry) and the reservoir engineering (site selection, reservoir geomechanics and potential evaluation). This symposium focuses on the fundamental aspects of understanding the fate of CO2 injected into deep reservoirs, the multi-physical, biogeochemical, and coupled interactions among CO2-brines, minerals, and hydrocarbons, and utilization strategies of CO2 in the subsurface (e.g. enhanced geothermal system, subsurface energy storage, and unconventional resources recovery by CO2). This symposium also welcomes innovated laboratory technologies and field investigations associated with fault reactivation and seal remediation during the large-scale sequestration and utilization of CO2.

CO2 Storage Associated with Enhanced Oil Recovery

Richard A. Esposito raesposi@uab.edu (USA)


Richard has over 28 years of experience in the electric utility industry in various roles and currently serves as Southern Company’s R&D Program Manager of Geosciences & Carbon Management. He works with a wide range of energy-related issues including Carbon Capture, Utilization, and Storage (CCUS), utility-scale energy storage, geothermal power, and deep well disposal of wastewater. Richard has a B.S. and M.S. degree in Geology and a PhD in Engineering with a focus on geologic storage capacity estimation in saline reservoirs, CO2-EOR pilot injection testing and certification of storage associated with CO2-EOR.

ISO TC 265 - CO2 Storage Using Enhanced Oil Recovery

Enhanced Energy Recovery using CO2

Regulatory frameworks for Certification of CO2 storage in oil and gas fields

CO2-Enhaned Oil Recovery (CO2-EOR) is the process of using wells to inject CO2 at pressures where CO2 mixes with the oil, changing its properties, and increases the volume of oil extracted from an oil field. At the same time, oil fields provide the geologic framework for large scale storage of CO2 both associated with CO2-EOR operations or after the oil field is depleted. CO2-EOR projects are designed as a closed-loop system whereby some of the injected CO2 is co-produced with the oil and then separated in above-ground recycling facilities prior to being re-injected into the oil field. Each cycle of injection results in a volume of CO2 that is trapped is referred to as “associated storage”. This “associated storage” volume of CO2 has direct environmental benefits as the oil field can serves as a safe and long-term storage opportunity that values the injected CO2 as a commodity. Demonstrating the safe long-term containment of CO2 in association with CO2-EOR and documenting the quantity of that CO2 stored is a driver in the expansion of EOR operations with use of anthropogenic CO2 that would otherwise be emitted to the atmosphere. The understanding oil field operations and the documentation of “associated storage” is important to CO2 generators especially given a price on carbon or tax incentive for secure storage. This symposium invits case studies from oil fields whereby CO2-EOR operations were performed to evaluate this value proposition including parallel efforts such as the development of standards for storage of CO2 in oil fields.
