This chapter describes the difficulties associated with formation evaluation in thinly bedded sandstone reservoirs and outlines the existing technology that has been applied to these difficulties. Chapter 2 introduces our integrated approach to evaluating hydrocarbon pore-thickness in thinly bedded clastic reservoirs.

Many terms are introduced in these two chapters through examples and informal definitions: for example, earth models, bed types, logging tool forward models, convolution, inversion, statistical earth models, and Monte Carlo inversion. These topics are discussed more thoroughly in Chapters 6 through 10, and the integrated approach is described in detail in Chapters 11 through 13. <...>

Petrophysics is the study of rock properties and their interactions with fluids (gases, liquid hydrocarbons, and aqueous solutions). The geologic material forming a reservoir for the accumulation of hydrocarbons in the subsurface must contain a three-dimensional network of interconnected pores in order to store the fluids and allow for their movement within the reservoir.

Обогащенные PGE–(REE–Ti) элементами включения микрометрового размера, минеральные ассоциации, вариации состава и потенциальный источник минералов платиновой группы в россыпной зоне Сисим, Восточные Саяны, Россия.

We report the results of a mineralogical investigation of placer samples from the upper reaches of the Sisim watershed, near Krasnoyarsk, in Eastern Sayans, Russia. The placer grains are predominantly Os–Ir–(Ru) alloys (80%) that host various inclusions (i.e., platinum-group elements (PGE)-rich monosulfide, PGE-rich pentlandite, Ni–Fe–(As)-rich laurite, etc.) and subordinate amounts of Pt–Fe alloys.

This book is a response to the rapid development of experiment and theory in high-pressure condensed-matter physics. The diamond-anvil cell (DAC) has revolutionized the field. Experiments are now routinely performed above 100 GPa, and the first phase transitions above 100 GPa have recently been reported. There is also progress along the temperature axis, with high sample temperatures produced either by immersing a heat-resistant diamond-anvil assembly in a heat bath or by focusing laser light onto the sample and recording the temperature pyrometrically. This latter technique can be used up to the highest known melting points near 5000 K. <...>
