Art of Petroleum Geoscience Exploration                                                                                                                   Duration: 5 Days

Most of the petroleum exploration and development geoscientists have spent a great deal of their careers working in the same country or sedimentary basin, where they amassed substantial professional expertise and have mastered familiar conditions and complexities with prepared available solutions. Any successful geoscientist must possess this quality, but one should be more qualified. But for them to advance as explorers, high-caliber professionals working on high-impact and high-risk opportunities must undergo extensive training in the science and art of exploring other parts of the world in a variety of tectonic and geological environments.
Why is it crucial for geoscientists to comprehend the geological circumstances and exploration difficulties in places where they had no idea working in the future? It is more likely that you will be able to relate them to the fields in which you have worked and think about them in ways that differ from conventional wisdom, giving you an edge over others, the more acquainted you are with other world basins.

Oilfields Economics
The petroleum economics is the study and analysis of the financial and economic aspects of the discovery, production, distribution, and use of oil and gas resources. It entails assessing expenses, income, market trends, investment choices, and the petroleum industry’s overall economic impact.

Innovative Exploration – New Plays and Reservoir
* How to define new plays * what are their essential to establish them as a viable target * Deeper or new reservoirs and untested Plays * Application of new and advanced technologies

Corporate Strategies for the Exploration
These strategies give a quick overview of the many different methods used in petroleum exploration and production to increase productivity, profitability, and sustainability.
* Conventional reservoir exploration * Unconventional resource development * Flexible Exploration Approach * Scenario Planning * Long-Term Vision * Enhanced Oil Recovery (EOR) * Integrated Reservoir Management * Risk Mitigation and Diversification * Explore diverse basins and regions to mitigate risk * Sustainable practices * Technological innovation * Embrace cutting-edge technologies like AI, data analytics * Advanced drilling techniques * Enhance efficiency, reduce costs, and improve accuracy * Collaborative partnerships * Portfolio management * Market-Oriented strategies * Role of new technologies in further exploration

Exercises
Teams will work together to analyse the cases that are given throughout the course while developing innovative exploration and production strategies. Their task would be to develop a convincing plan that complemented management’s objectives and partner expectations. What is the end goal? a business that effectively integrates sustainability and commercial profitability.
Decision making for the risk-based prospects needs to be a very careful task given to the exploration team as the management of the oil companies mainly depend on the wisdom of their decision. What factors need to be evaluated carefully and how risk mitigation is possible, both theoretically and with practical standpoint will be taught in the course.

The course will provide hands-on exercise for the participants to cope with the situation a exploration usually encountered in their professional routines.

The course contents will provide insight into the theory and application part of the exploration business due to the trainer’s own expertise in local and global experience who remained part of some of the key oil and gas discoveries.

Presentations
On the final day of the course, every student who participated in the team exercises in the classroom may be given a chance to discuss their findings. However, it will depend on how long the course lasts because we’ll try to complete all the assignments in the allotted time.
