Exercise chapter 5-HC generation & migration 1/ A) What group of organisms is the fundamental biomass contributor to the oceans? B) What are the two major factors that control the distribution of this group? 2/ What two geological settings favor the preservation of organic matter in finegrained sediments? 3/ Match each of these types of kerogen particles with the phrases below by placing the correct letter in the space provided A Vitrinite B Exinite C Inertinite D Amorphous particles is derived from spores, pollen, algae and leaf cuticle waxes. is not strictly a maceral group is the major component of Type III kerogen. consists of recycled oxidized organic matter, like charcoal. when dominant in kerogen, the major hydrocarbon produced is methane. is the major component of Type II kerogen. is barren in terms of hydrocarbon production potential is the most resistent particle to chemical and physical breakdown. is the most common particle type in coal 4/ On the graph, (Figure 1) name and number the four different types of kerogen Name and label the three stages where kerogen is immature, where it generates oil and gas, and where it is overmature Figure 5/ Label the blanks on the petroleum generation graph with regard to types of petroleum, average depth and temperature (Figure 2 ) Figure 6/ A) Describe the lithology of the Green River oil shale of the western United States B) What was the depositional environment? 7/ How does primary migration differ from secondary migration? 8/ What are the two major obstacles to overcome in developing models of primary migration? 9/ What three factors are mainly involved in secondary migration?
