Surface Geochemical Exploration for Oil and Gas Course
Introduction:
The great majority of oil and gas pools and mature source rocks have recognizable surface geochemical expression. The O&G industry devotes significant time and resources in finding and defining traps, but little or none in establishing the likely presence of hydrocarbon in those traps, especially for older onshore basins.
This program will cover surface geochemical and non-seismic detection of oil and gas, the variety of surface and near-surface methods for high-grade basins and plays, and the pre-drilling prediction of hydrocarbon charge. Explorationists will learn the techniques and methodologies that will help refine the economic evaluation of reservoirs before investing in new plays. Explorationists will be able to learn how surface geochemical exploration methods can be complementary to existing seismic and geological methods. This will be tackled during the discussion sections on survey design, frontier basin evaluation, high grading leads and prospects, applications for field development, data interpretation and integration, and scores of exploration examples. The course is illustrated from a wide range of international basins and plays, structural and stratigraphic case studies, onshore and offshore examples, and also the application to shale-chalk plays. The methods that will be discussed in this course can help reliably predict 70%-80% of subsequent commercial discoveries, and about 90% of the eventual dry holes.
Course Objectives:
- INTEGRATE the surface geochemical data from hydrocarbon detection surveys to value add to geologic and seismic exploration methods
- APPLY surface geochemical data to identify traps most likely to be charged with hydrocarbons
- GAIN understanding of hydrocarbon seepage and microseepage, as well as seepage characteristics, mechanisms, and rates
- APPLY direct and indirect geochemical, remote sensing, and non-seismic geophysical methods available for hydrocarbon detection
- ANALYZE varied surface and near-surface expressions of hydrocarbon seepage and microseepage - geochemical, mineralogic, and geophysical
- EXECUTE proper survey design and survey method selection
- AVOID pitfalls in acquisition and interpretation of geochemical and non-seismic data
