Book Description
Numerical simulations indicate that hydrocarbon migration and entrapment in stacked fault-bounded reservoirs are mainly affected by the following factors: charge time, faults, pressure and geological structures. The charge time for commercial hydrocarbon accumulation is much longer in oil-water systems than in oil-gas-water systems. Faults are classified into charging faults and 'back doors' faults other than charging faults in stacked fault-bounded reservoirs. The lower the displacement pressure of a fault, the higher its updip oil transportation ability. The downdip oil transportation ability of a fault is usually low and cannot cause commercial downdip oil accumulation. Back doors affect both hydrocarbon percent charge and hydrocarbon migration pathways. Updip back doors improve updip oil charge. The lower the displacement pressure of an updip back door, the more efficient the updip oil charge before 3,000 years. Back doors whose displacement pressure is equal to or higher than 28.76 psi are effective in sealing faults in oil-water systems. On the contrary, only sealing faults result in commercial gas accumulations in stacked fault-compartmentalized reservoirs. Otherwise gas is found over oil. Downdip back doors generally have few effects on downdip hydrocarbon charge. Geopressure enhances the updip oil transportation of a fault and improves the positive effects of updip back doors during updip oil charge. Geopressure and updip back doors result in more efficient updip oil charge. A physical barrier is not necessarily a barrier to oil migration with the aid of geopressure and updip back doors. The chance for hydrocarbon charge into reservoirs along growth faults is not equal. Any one of the above controlling factors can change the patterns of hydrocarbon charge and distribution in such complex geological structures. Generally, lower reservoirs and updip reservoirs are favored. Reservoirs along low-permeability charging faults may be bypassed. Gas can only charge the updip reservoirs. Both updip and downdip back doors can facilitate oil penetrating a barrier fault to charge reservoirs offset by the barrier fault. Interreservoir migration among stacked fault-compartmentalized reservoirs is an important mechanism for hydrocarbon accumulation and trap identification. The interreservoir migration is a very slow process, even though the displacement pressures of bounding faults may be very low.

Book Description
This book presents the authors' research findings on the dynamics of oil migration, research methodologies, insights and applications in petroliferous basins. It studies the behaviors of oil migration in porous media through physical experiments and numerical simulations, explores the mechanism of oil migration and effects of migration process, and then establishes a migration modeling method by coupling the source, driving forces and carriers. The new method can be used to estimate the amount of migrated hydrocarbons and then predict the location of possible hydrocarbon accumulations in different parts of a basin. This approach is useful for resources assessment and prediction of the distribution of hydrocarbon accumulations. An example utilizing this methodology is presented to study the dynamics of migration and accumulation processes in the southern slope of Dongying Depression in Bohai Bay Basin in China. The book appeals to scientists and professionals working on petroleum prospecting as well as faculty and students in petroleum geology.

Book Description
The purpose of the conference from which this volume is the outcome was to gather international experts from industry and academia to examine the process of hydrocarbon migration and its varied near-surface expressions. The wide range of topics discussed is reflected in the papers published: near-surface manifestations of hydrocarbon migration; hydrocarbon-induced alteration of soils and sediments; migration mechanisms; hydrocarbon flux measurements; sampling and analytical techniques; survey design and interpretation; implications of hydrocarbon leakage; and exploration case studies.

Book Description
The latest volume in the Developments in Structural Geology and Tectonics series from Elsevier, Tectonic and Structural Framework of the Zagros Fold–Thrust Belt is a collection of the most up-to date research and developments in the unique tectonic and structural geology of the Zagros. The Zagros fold–thrust belt is famous among geologists and is one of the most-studied terrains in the world. Because of its unique structures, the Zagros orogeny is challenging for many researchers and experts; this book is the essential reference that collates the newest data and fully explores that aspect. In addition, because the Zagros range is a potential source for hydrocarbons, it is of interest to petroleum geologists and exploration companies worldwide. This book is an essential, cutting-edge reference for oil companies, structural geologists, and students at both the undergraduate and postgraduate levels. Includes valuable new data about one of the most famous collisional mountain ranges in the world, the Zagros fold–thrust belts, as a guide for other collisional ranges such as the Himalaya, the Alps, and the Andes, as they share common fundamental deformation mechanisms Provides research from geologists across the world, with the goal of understanding the unique dynamics and kinematics of the Zagros range

Book Description
Dolostone units of the Lower Ordovician Beekmantown Group host a number of occurrences of natural gas in southern Quebec. The nature of the hydrocarbons that fill the dolostone pores, and the ages of hydrocarbon migration and late-stage calcite cementation events, are important in assessing the reservoir quality of the dolostone units. This paper reports preliminary observations to address these questions, based on examination of Beekmantown samples and their fluid inclusions. The paper begins with background on the geological setting of the Beekmantown Group in the Montreal area, then discusses the petrography and paragensis of dolostone units from the Theresa and Beauharnois formations of the Group. Results of fluid inclusion studies are presented to elucidate the timing of hydrocarbon activities and estimate the temperature & pressure conditions undergone by the units.
