No prior knowledge in geology is assumed and the course starts from basic geological concepts (e. minerals, igneous rocks, sedimentary rocks, metamorphic rocks, rock deformation and geological time) then moves onto the petroleum system (e. source rocks, reservoir rocks, sealing rocks, maturation, migration and trapping of hydrocarbons) and finally introduces the tools used in petroleum exploration (seismic surveying, drilling and logging). 8/25/2015 Thai Ba Ngoc – Faculty of Geology & Petroleum Engineering - HCMUT 4 Content Throughout the semester one lecture per week is also given by a guest speaker from different sectors of the petroleum industry in order to provide an overview of the petroleum industry.
Theoretical concepts introduced during the lectures are applied during an overnight feilf trip, which provides a small group discovery experience as students work in small teams to make a geological map. 8/25/2015 Thai Ba Ngoc – Faculty of Geology & Petroleum Engineering - HCMUT 5 Objectives • Understanding the major physio-lithology of oil and gas reservoir • Understanding the principle and mechanism of trap. • Understanding the basic principles and approach in seal study • Understanding and determining the hydrocarbon generation and migration • Understanding and analyzing the subsurface in hydrocarbon generation and preservation • Application of subsuface map and X-section • The habitate of hydrocarbon in sedimentary basin • The ability to determine the appropriate hydrocarbon exploration methods 8/25/2015 Thai Ba Ngoc – Faculty of Geology & Petroleum Engineering - HCMUT 6 A bit about me •Education:B., Hydrogeology & Engineeringgeology, Ho Chi Minh City University of Technology, Vietnam, 2009., Petroleum Geology_Application, Ho Chi Minh City University of Technology,Vietnam, 2012. •Lecturer at The University of Technology, 2009– Present • Academic Awards ü Outstanding graduates 2009 ü Fellowship of spe 2005 ü Typical young teachers ü Chaired many scientific topics ü Published many scientific articles in journals and conferences • Work Experience Description: teaching and participating research in the field: Reservoir Engineering, Reserve Estimation, Modeling and Simulation, Applied Hydrogeology for O & G exploration, O & G formation evaluation, Geotechnics, Geostatistics, Applied Mathematics for Petroleum Science.

Geology itself is firmly based on chemistry, physics, and biology, involving the application of essentially abstract concepts to observed data.
In the past these data were basically observational and subjective, but they are now increasingly physical and chemical, and therefore more objective. Geology, in general, and petroleum geology, in particular, still rely on value judgments based on experience and an assessment of validity among the data presented. It is now appropriate to consider in more detail the roles of chemistry, physics, and biology in petroleum exploration (Fig. 8/25/2015 Thai Ba Ngoc – Faculty of Geology & Petroleum Engineering - HCMUT 19 Relationship of Petroleum Geology to Science Figure 1.
The relationship of petroleum geology to the pure sciences 8/25/2015 Thai Ba Ngoc – Faculty of Geology & Petroleum Engineering - HCMUT 20 Chemistry and Petroleum Geology The application of chemistry to the study of rocks (geochemistry) has many uses in petroleum geology. Detailed knowledge of the mineralogical composition of rocks is important at many levels. In the early stages of exploration, certain general conclusions as to the distribution and quality of potential reservoirs could be made from their gross lithology. For example, the porosity of sandstones tends to be facies related, whereas in carbonate rocks this is generally not so.
Detailed knowledge of the mineralogy of reservoirs enables estimates to be made of the rate at which they may lose porosity during burial, and this detailed mineralogical information is essential for the accurate interpretation of geophysical well logs through reservoirs. Knowledge of the chemistry of pore fluids and their effect on the stability of minerals can be used to predict where porosity may be destroyed by cementation, preserved in its original form, or enhanced by the solution of minerals by formation waters. Organic chemistry is involved both in the analysis of oil and gas and in the study of the diagenesis of plant and animal tissues in sediments and the way in which the resultant organic compound, kerogen, generates petroleum. 8/25/2015 Thai Ba Ngoc – Faculty of Geology & Petroleum Engineering - HCMUT 21 Physics and Petroleum Geology The application of physics to the study of rocks (geophysics) is very important in petroleum geology.
In its broadest application geophysics makes a major contribution to understanding the earth's crust and, especially through the application of modern plate tectonic theory, to the genesis and petroleum potential of sedimentary basins. More specifically, physical concepts are required to understand folds, faults, and diapirs, and hence their roles in petroleum entrapment. Modern petroleum exploration is unthinkable without the aid of magnetic, gravity, and seismic surveys in finding potential petroleum traps. Nor could any finds be evaluated effectively without geophysical wireline well logs to measure the lithology, porosity, and petroleum content of a reservoir.
8/25/2015 Thai Ba Ngoc – Faculty of Geology & Petroleum Engineering - HCMUT 22 Physics and Petroleum Geology 8/25/2015 Thai Ba Ngoc – Faculty of Geology & Petroleum Engineering - HCMUT 23 Biology and Petroleum Geology Biology is applied to geology in several ways, notably through the study of fossils (paleontology), and is especially significant in establishing biostratigraphic zones for regional stratigraphical correlation. The way in which oil exploration shifted the emphasis from the use of macrofossils to microfossils for zonation, has already been noted. Ecology, the study of the relationship between living organisms and their environment, is also important in petroleum geology. Carbonate sediments, in general, and reefs, in particular, can only be studied profitably with the aid of detailed knowledge of the ecology of modern marine fauna and flora.
Biology, and especially biochemistry, is important in studying the transformation of plant and animal tissues into kerogen during burial and the generation of oil or gas that may be caused by this transformation. 8/25/2015 Thai Ba Ngoc – Faculty of Geology & Petroleum Engineering - HCMUT 24 Relationship of Petroleum Geology to Petroleum Exploration and Production Geologists, in contrast to some nongeologists, believe that knowledge of the concepts of geology can help to find petroleum and, furthermore, often think that petroleum geology and petroleum exploration are synonymous, which they are not. Theories that petroleum is not formed by the transformation of organic matter in sediments have already been noted. If the petroleum geologists' view of oil generation and migration are not accepted, then present exploration methods would need extensive modification.
Some petroleum explorationists still do not admit to a need for geologists to aid them in their search. In 1982 a successful oil finder from Midland, Texas, admitted to not using geologists because when his competitors hired them, all it did was increase their costs per barrel of oil found. The South African state oil company (SOEKOR) was under a statutory obligation imposed by its government to test every claim to an oil- finding method, be it dowsing or some sophisticated scientific technique. These examples are not isolated cases, and it has been argued that oil may better be found by random drilling than by the application of scientific principles.
