Lecture organized by SPG India, MUMBAI Chapter on
“Utility of Geo-potential Method in Hydrocarbon Exploration”
Delivered by Prof. Anand S. P., Indian Institute of Geomagnetism, Mumbai
SPG Mumbai Chapter organised a technical presentation as a part of continuous and relentless efforts of SPG to share ideas and experiences to the geo-scientific community and to express & exchange views on “Utility of Geo-potential Method in Hydrocarbon Exploration” on 17th April, 2024, under the guidance of Shri B.S. Bora, ED-CGS, President and Shri Vikas Mohan, HGS, Secretary, SPG Mumbai Chapter. The technical presentation was delivered by Dr. Anand S. P., (Professor E), Indian Institute of Geomagnetism, Mumbai. The presentation was organised at ONGC NBP Green Heights Conference Hall and more than 60 participants from different work centres in Mumbai, including SPG members attended it.
Shri B.S. Bora, ED-CGS, President SPG Mumbai Chapter delivered the opening remarks. He introduced the distinguished speaker, Dr. Anand S. P. and the importance of the subject.
Brief biodata of Dr. Anand S. P., Prof. (E), Indian Institute of Geomagnetism, Mumbai
Dr. Anand S.P. is a Professor E at Indian Institute of Geomagnetism (IIGM) Mumbai with extensive experience and expertise in Sub-basalt imaging using Geo-potential methods, structure and evolution of Aseismic Ridges in the Northern Indian Ocean. With a distinguished career spanning over twenty years, he has made significant contributions to the field through his research, publications, and academic endeavours.
One of his important contributions to the field of Geoscience is the publication of composite magnetic anomaly map of India and its contiguous region, the first of its kind, where magnetic data collected from different platforms, organizations and agencies were integrated to generate the composite anomaly map. He carried out and was part of projects funded by ISRO (SAC-Space Applications Centre), ONGC, DST etc. In probably a first such exercise carried out in India, his survey planning, meticulous processing and interpretation of magnetic data helped to successfully delineate archaeological structures in the Keeladi archaeological site, Tamil Nadu. Currently, Dr. Anand is developing techniques for sub-basalt imaging using gravity and magnetic data in the Deccan Volcanic Province and the Western Continental Margin of India and also generating a lithospheric magnetic anomaly map of India from satellite data. Dr. Anand was a part of the Continuing Education Program of Society of Petroleum Geophysicists, member of National Aero-Geophysical Mapping Program (NAGMP) committee and has been invited by GSI to deliver lectures on Exploration Geomagnetism during orientation programs, workshops etc
The talk covered various aspects of geopotential method, its theory, application, usefulness and importance. Dr. Anand explained the theory of geopotential method in a very simple way, which was imprinted on the audience’s mind. He quoted from published papers about the improvements in Magnetic prospecting for hydrocarbon. Geopotential method for hydrocarbon exploration has transformed from a mere reconnaissance tool to a method that can now provide levels of detail that are compatible to those derived from other geophysical methods
Multiple case studies were also presented by Dr. Anand.
- Case studies of Frontier Basin-Basement Depth
- Mapping IS Sources and Basement and Intra sedimentary Mapping
- Seep-Induced Magnetic Anomalies &
- Magnetic imaging of intra-sedimentary anomalies and their association with hydrocarbon producing fields in the Niger Delta, Nigeria
Intra-sedimentary Mapping (ISMAP) for hydrocarbon exploration involves the use of highsensitivity, high-resolution aeromagnetic data to resolve very low amplitude (5nT) anomalies originating from structures within the essentially non-magnetic sedimentary column, as well as high amplitude features from the crystalline basement. ISMAP detects structures from within the sedimentary column as well as determining the depth to, and structure of, the magnetic basement. The benefits of ISMAP are realized through the improved data processing techniques used. These include tie-line levelling, micro-levelling, equivalent source corrections where appropriate, and signal enhancement filtering, which permits the retention of the high frequency component of the data during the contour mapping. ISMAP surveys are particularly useful in identifying linear or curvilinear features originating from sources within the sedimentary section
The talk was highly informative and succeeded in generating great interest among the audience. Geoscientists present in the session actively interacted with the speaker during the talk.
The technical session was followed by closing remarks by Shri Nandan Verma, ED-Basin Manager, WOB. SPG Mumbai chapter felicitated guest speaker Dr. Anand S.P. for his contribution with a memento as a token of appreciation. Finally, Shri Amit Kumar, SG (S), Jt. Secretary, SPG Mumbai Chapter delivered the vote of thanks.
Society of Petroleum Geophysicists (SPG) & Association of Petroleum Geologists (APG), (Vadodara Chapters)hosted their Annual Technical Meet jointly on 22nd July 2023 at ONGC Officers Club Vadodara. A large number of Geoscientists including retired senior officers from ONGC and students from MS Universityalso attended the event.
ED-Basin Manager Sh. P. R. Mishra presided over the meet. The event featured two distinguished geoscientists as speakers: Prof. M.G. Thacker, HOD, Department of Earth and Environment Science, KSKV Kachchh University and Prof. Dhananjay Sant, Faculty of Science, Maharaja Sayajirao University of Baroda.
The afternoon session witnessed delivering of two thought-provoking, interactive talks. The first one was by Prof. M.G. Thacker on the topic “Geo-tectonic evolution of Kachchh paleo-rift Basin”. It was followed by another very enlightening talk by Prof. Dhananjay Sant on the topic 'Kachchh Basin: New Insights'.
In the first presentation, Prof. Thacker explained in great detail the evolution of Kutch Basin from Late Triassic onwards. Kutch basin is a rift basin which formed when India separated from Gondwanaland in Late Triassic. Synrift sedimentation took place in Half-Grabenal settings during Mid to Late Jurrasic.
Post-Rift sedimentation took place during Early cretaceous. This was followed by Deccan volcanism and Indo Eurasian Collision. Quaternary tectonics are still active in Kutch and signs of that can be observed like fault cuts, folds etc
He also stressed upon how Kutch is one of the few places in India where great number of geological features have been preserved in pristine condition due to its Arid Climate. Sequence boundaries of various horizons are also clearly observed in Kutch. As ONGC forays into new plays to further explore new regions, Kutch Basin has come up as a front runner.
Recently APG VRC has also conducted 2 field trips to Kutch Basin to better understand its geology. Kutch has also been an integral region to study fossil evolution. Many fossils like dinosaur bones fragments, corals, trace fossils as well as completely preserved Ichthyosaurus have been discovered here.
The second talk was delivered by Prof. Dhananjay Santon the topic ‘Kachchh Basin: New Insights’. There he discussed Kachchh basin in context of major structural elements in the Indus basin. He also discussed about shallow subsurface mapping of major and minor faults and seismicity along Kachchh mainland fault.
He elucidated his research work on HVSR technique, as a tool to map the extension of rock outcrop / features in subsurface, and to demarcate distinct rheological contrasts up to depth of 2000m. Microtremor surveys use ambient noise as the signal. The ability of the survey to generate rapid single station records at required resolution and cost effectiveness of the operations, are some of the incentives of using a microtremor survey

Prof. Sant then presented his research work in Kachchh region, a maiden attempt to map shallow subsurface rheological interfaces laterally across the Banni Plains and to decode geometry of the antecedent faults associated with the Kachchh Mainland Fault using the microtremor method. Prof. Sant further clarified that the ambient noise encapsulates fundamental resonant frequency of the sediment layers. These resonant frequencies derived from the microtremors show strong correlation with the velocity of the Rayleigh waves and the thickness of the sediments
The technical event garnered significant participation and engagement from SPG and APG members of WON Basin. ED - Basin Manager Shri PR Mishra highlighted the importance of such technical sessions and encouraged the continuation of such programs.
The evening brought delightful entertainment with a mesmerizing cultural program presented by an Orchestra Group from outside, followed by an interactive dinner.
