Geology & Geophysics technology advances will be greater to meet the challenges of fnding the smaller felds, more subtle traps and traps in hard-to explore areas and reduc- ing costs.
A typical question is often simply “How do we start?” followed by “How can an objective and audit- able assessment be made, what are the controlling factors, what data is needed and which factors are really important?” As always, the geology is the starting point and resource assessments are only meaningful if they take the petroleum system Visualize the interplay between regional tectonics, salt morphology, and the over- risk factors that control burden to identify potential oil and gas traps. Combine powerful 3D rendering and advanced edge-detection attributes with multi-Z salt interpretation for delineation and the development of the characterization diapirs, domes, and other salt structures.
