Depth imaging is changing the face of seismic technology. First and foremost, depth imaging greatly extends our ability to image geologic structure. This is true not only for highly complex structures such as thrust imbricates and subsalt structures, but also for subtle structural plays like fault shadows. In fact, since the late 1980’s, almost all structural play exploration has been stalled at the frontier where time imaging is no longer effective. In the 1990’s depth imaging has taken us through this frontier and is renewing many of these structural plays.

The purpose of this course is to introduce you to Petrel Geophysics functionality and the workflows. You will go thorough different functionalities in Petrel and learn how to efficiently use these for interpreting 2D/3D seismic data. The powerful tools and algorithms can be used to calculate size/area of your leads and prospects which, in turn, can be used for reserves estimation.
You will be provided with a ready-to-use Petrel 2013 project containing 2D/3D seismic and well data.
The exercises provide hands on training that enables you to explore the functionalities through dedicated exercises. <...>

Analyses of geological structures from field exposure of rocks have been one of the important and intriguing disciplines in (applied) Earth Sciences. Since the 1990s, especially after the boom of three‐dimensional seismic technologies, reflection seismic data in two and three dimensions have become the modern ‘field’ for geologists. A large number of exploration geoscientists analyze reflection seismic data to interpret sedimentary sequences and deformation structures to provide prospective leads for exploration in their respective industries. Today, seismic data are used extensively in industries such as hydrocarbon and mineral exploration, carbon dioxide sequestration, sea floor hazard surveys for cables and pipelines and so on. This book primarily deals with reflection seismic data in the hydrocarbon industry.

В монографии дается точная постановка задач на волновое продолжение сейсмических полей, зарегистрированных иа дневной поверхности; выясняются пределы возможностей восстановления поля в среде иа основе позиционных сейсмограмм; выводятся формулы для волновых продолжений полей в произвольные акустические и упругие среды и даются алгоритмы определения структурных элементов таких сред. Изучение волновых продолжений производится со спектральной точки зрения, причем основное внимание уделяется выяснению их избирательности и свойства локальности. Исходя из свойства локальности предлагаются .различные эффективные алгоритмы построения продолженных полей и определения структурных элементом среды, позволяющие развивать последовательную систему интерпретации результатов сейсмических наблюдений. В заключение кратко освещается опыт применения волновых продолжений полей к задачам практики <...>

В работе приведены результаты сейсмотектонических исследований, выполненных в целях оценки сейсмической опасности Ставропольского края. Выявлены основные черты неотектонических структур, изучена история их развития в неоген-четвертич-ный, четвертичный и голоценовый периоды, проанализирован современный морфоструктурный план и выделены активные разломы. На основе детального анализа данных повторного нивелирования установлена повышенная современная активность Ставропольского свода со скоростями современных вертикальных движений земной поверхности до 3-6 мм/год, зафиксировано опускание в районе г. Кропоткина до 5 мм/год, выделены зоны контрастных вертикальных движений с перепадами скоростей до 20 мм/год.

In the geological sciences, the term "tectonics" refers to the processes, structures and landforms associated with deformation of the Earth's crust. In a broader sense, it refers to the evolution of these structures and landforms over time. On a global scale, we are concerned with the origin of continents and ocean basins, he which are the largest landforms produced by tectonics on Earth At the regional scale, we are-interested in structures that produce mountain chains. <...>

This book contains three major physical phenomena for active source seismology: underwater explosions, underground nuclear explosions and large-scale on-surface chemical explosions.
In particular we attempted to demonstrate how to use the technologies and applications in active source seismology and seismo-acoustics rather than the theoretical approach for the resolution as forensic explosion seismology in the light of an application for Defense Sciences.

Seismic hazard and risk analyses underpin the loadings prescribed by engineering design codes, the decisions by asset owners to retrofit structures, the pricing of insurance policies, and many other activities This is a comprehensive overview of the principles and procedures behind seismic hazard and risk analysis. It enables readers to understand best practises and future research directions.
