COURSE OVERVIEW:

Gravity and Magnetics for Explorationists provides a deep dive into the use of potential field methods for subsurface mapping and resource identification. While seismic data remains the primary tool for detailed imaging, gravity and magnetic surveys offer a cost-effective and essential regional perspective, particularly in frontier basins and areas with complex salt or volcanic cover. This course explains the physical principles of density and magnetic susceptibility contrasts and how these variations are measured from air, sea, and land platforms to reveal the hidden architecture of the Earth's crust.

The coverage includes the processing and enhancement of raw potential field data through filtering, derivatives, and downward continuation to sharpen anomalies. Participants will learn how to integrate these datasets with seismic and well data to build more accurate structural models. The scope extends to the interpretation of basement depth, the identification of igneous intrusions, and the mapping of regional fault networks that control hydrocarbon migration. By understanding the "non-uniqueness" of potential field solutions, explorationists can use gravity and magnetics to constrain geological models and reduce exploration risk in both conventional and unconventional plays.

Furthermore, the course explores the latest advancements in technology, such as satellite-derived gravity and high-resolution gradiometry. The training focuses on the practical application of 2D and 3D modeling and inversion techniques to convert potential field anomalies into meaningful geological cross-sections. This integrated approach ensures that explorationists can identify "sweet spots" and evaluate basin-scale potential more effectively. By the end of the course, attendees will be equipped to design potential field surveys and interpret the results to provide a competitive advantage in the search for energy resources.

TARGET AUDIENCE:

Exploration Geologists, Geophysicists, Basin Analysts, and Interpretation Geoscientists who want to enhance their structural and regional mapping capabilities.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
