Seismic data processing / Обработка сейсмических данных. Том 3

Хотя методы миграции, рассмотренные в Главе 4, основаны на предположении о слоистой среде, простые изменения, вносимые в основные алгоритмы, обеспечивают их точность в ситуациях, когда скорость незначительно изменяется в горизонтальном направлении. Например, среднеквадратичные скорости могут изменяться в горизонтальном направлении в миграции Кирхгоффа. В конечноразностном методе, пока вариации скорости в латеральном направлении остаются незначительными, элемент тонкой линзы может быть опущен (см. Приложение С.2), и скоростная функция, используемая в элементе дифракции, может изменяться в латеральном направлении. В f-k-методе (миграция Stolt) приведение в соответствие с вариациями скорости в латеральном направлении осуществляется путем изменения коэффициента растяжения от 0 до 1. Даже при изменении скорости результатом этих трех методов является временной разрез и, следовательно, термин «миграция во времени».

Seismic Exploration of Hydrocarbons in Heterogeneous Reservoirs / Сейсморазведка углеводородов в неоднородных коллекторах

Over the past decade, the world’s petroleum and natural gas consumption exceededfour times the expected oil/gas reserves so that the supply from oil companies could not meet the demands of human activities. The difference between proven reserves and increasing demands is still growing and the remaining recoverable reserves could run out in 40 years according to the latest oil/gas production rate <...>

Seismic imaging of carbonate reservoirs and systems. Volume 81 / Сейсмическое изображение карбонатных резервуаров и систем

Recent advances in seismic acquisition, processing, and visualization techniques provide the opportunity to image carbonate reservoir architecture with unprecedented resolution. In particular, the increase in threedimensional (3-D) seismic data acquisition and the improvements in processing techniques have contributed to these advances and have resulted in higher-resolution imaging of sedimentary bodies. In addition, the analysis of seismic attributes is a developing methodology to quantify the volumes and rock properties of these bodies (Masaferro et al., 2004). These advances in volume visualization that allow imaging of the morphology of ancient carbonate systems rivals images from satellite data in the modern environments (Figure 1).

Seismic Inversion Methods: A Practical Approach / Методы сейсмической инверсии: практический подход

Seismic inversion methods in geophysics is a technique used to transform seismic reflection data into quantitative subsurface rock properties. It is methods to integrate seismic reflection data along with well log data to extract a variety of petrophysical parameters. Geophysicists regularly perform seismic surveys to collect subsurface geological information in the exploration project.

Seismic stratigraphy and depositional facies models / Сейсмостратиграфия и модели отложения фаций

Application of seismic stratigraphic techniques is nowadays standard practice for interpreting seismic datasets. The advantage of seismic stratigraphy for geological studies lies in the fact that the method combines different scales of observation: large scale remote sensing seismic measurements and the high-resolution well control logging / outcrop approach (Veeken 2007). Many workers have embraced seismic stratigraphic principles to add value to their seismic observations (e.g. Payton et al. 1977, Brown and Fisher 1976 and 1980, Rochow 1981, Halbouty 1982, Berg and Woolverton 1985, Bally 1987, Wilgus et al. 1988, Ziegler 1990, Armentrout and Perkins 1991, Cramez et al. 1993, Den Hartog Jager et al. 1993, Henri 1994, Brown 1999, Cosentino 2001, Biju-Duval 2002, Davies et al. 2004, Pomerol et al. 2005, Catuneanu 2006, Miall 2010). The proposed seismic interpretation procedure represents a systematic workflow that has proven to be a very powerful prediction tool for the evaluation of the subsurface structuration <...>

Seismic vulnerability index assessment framework of RC structures / Система оценки индекса сейсмической уязвимости RC-сооружений

Seismic risk management in many countries around the world is a subject of crucial interest to today’s societies as the destructive effects of recent powerful earthquakes cannot be overlooked or ignored. Some of these seismic disasters that have hit Sabah (Malaysia) in 2015, Gorkha (Nepal) in 2015, Northwest Ecuador in 2016, Amatrice (Italy) in 2016, and Chaiapas (Mexico) in 2018 have affected millions of people and caused severe economic losses (Parra et al. 2016; Adhikari et al. 2015; Ramirez-Herrera et al. 2018; Faenza et al. 2016).
Accordingly, seismic design codes and frameworks are typically applied or improved after each earthquake disaster, but older buildings have not been updated to take advantage of these new methods, and they have shown poor behavior when subjected to the same seismic standards as newer constructions. <...>

Seismic wave propagation modeling and inversion / Моделирование распространения сейсмических волн и инверсия

The propagation of energy via waves is a familiar phenomenon in our everyday life. The particular waves to be studied here are seismic waves which are intentionally created to image the interior of the earth [1], [8] and [21]. Our three dimensional earth consists of more than the geological structures we are accustomed to thinking about, much of the earth is fluid or fluid-like. Here the principal fluids of interest are hydrocarbons. The other essential fluid to consider is water. The fluid-like materials include the many gases trapped in earth, gases like carbon dioxide, helium, and natural gas. Actually, we may not be aware of the less visible subsurface structure, but all of the surface geology you can observe, and more, exists in some form under the surface <...>
