Exercise Caâu 1: A) What group of organisms is the fundamental biomass contributor to the oceans? Group of organisms is algage which is originally formed through photosynthesis B) What are the two major factors that control the distribution of this group? They are phytoplankton and bottom dwelling algae Caâu 2: What two geological settings favor the preservation of organic matter in fine-grained sediments? Rapid rate deposition and stratified ,oxygen-poor water bodies with anoix bottoms Caâu 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 Exinite is derived from spores, pollen, algae and leaf cuticle waxes Amorphous particles is not strictly a maceral group Vitrinite is the major component of Type III kerogen Inertinite consists of recycled oxidized organic matter, like charcoal Vitrinite when dominant in kerogen, the major hydrocarbon produced is methane Amorphous particles is the major component of Type II kerogen Inertinite is barren in terms of hydrocarbon production potential Vitrinite is the most resistent particle to chemical and physical breakdown Vitrinite is the most common particle type in coal Caâu 4: On the graph, ( Figure ) 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 Caâu 5: Label the blanks on the petroleum generation graph with regard to types of petroleum, average depth and temperature ( Figure 2) Figure Caâu A) Describe the lithology of the Green River oil shale of the western United States B) What was the depositional environment? Solution Caâu : How does primary migration differ from secondary migration? Di cư nguyên sinh : giai đoạn đầu q trình di cư ,tính từ lúc dầu sinh từ source rock di cư vào kênh dẫn Di cư thứ sinh :bắt đầu từ lúc dầu vào kênh dẫn di cư đến bể chứa Caâu 8: What are the two major obstacles to overcome in developing models of primary migration? The two major obstacles are the small pore size of the source rocks and the low solubility of hydrocarbon in water Caâu 9: What three factors are mainly involved in secondary migration? They are : ª Bouyance ª Capillary pressure ª Hydrodynamic flow
