Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
This work began while Satinder Chopra worked for Coherence Technology Company (CTC), which later became part of Core Laboratories. Chopra is particularly indebted to Vasudhaven Sudhakar (Sudha), who first introduced him to coherence-cube technology. Sudhakar’s belief in Chopra’s abilities sustained him in this work, wherein the intriguing and fascinating aspects of an emerging technology are revealed. Chopra also is indebted to his former CTC/Core Laboratories colleagues Bob Stevens, Laura Evins, and Vladimir Alexeev, who were always willing to help. Thane McKay and Rob Howey have been particularly encouraging and supportive of this writing effort and are gratefully acknowledged. Several examples included in the text have been borrowed from the work of Chopra’s other former colleagues, which he and Kurt J. Marfurt gratefully acknowledge. <...>
Now that this book has been in use, through various editions, for more than 22 years, I must reflect on the many contributions that have ensured its success. Most particularly I must thank Bill Abriel, Rebecca Latimer, David Roberts, Greg Partyka, Malcolm Lansley, Les Denham, and Dave Agarwal for writing sections for me. Many people, too numerous to name, have kindly released data examples and discussed their interpretations with me. AAPG and SEG have cooperated in the book’s publication since the Fifth Edition. Anne Thomas has edited all editions. The high quality of the product depends significantly on her editorial expertise.
Сейсморазведка играет выдающуюся роль в поисках углеводородов, и состоит из трех основных стадий: регистрации данных, их обработки и интерпретации. Эта книга предназначена для оказания помощи интерпретатору, который знает основы методик, используемых в обработке сейсмических данных. В частности, акцент делается на практических аспектах анализа данных.
In the last fifty years, there have been major advances in the acquisition, processing and interpretation of seismic reflection data. These advances have been driven largely by the spectacular developments in the electronic and computer industries. The first was the common midpoint (CMP) method for acquiring data (Mayne, 1962). CMP methods improve the signal-to-noise (S/N) ratios of primary reflections through stacking redundant data.
Since the first edition of 3D Seismic Survey Design appeared in 2002, seismic data acquisition has seen many changes, most of which have been captured in this second edition. This book by Gijs Vermeer describes in detail the properties of 3D acquisition geometries and shows how these properties naturally lead to the 3D symmetric sampling approach to 3D survey design. Many examples from the literature are used to illustrate good and less good choices of acquisition parameters. The link between survey parameters and noise suppression as well as imaging is an intrinsic part of the contents. This book should be of great interest to the designer of 3D seismic surveys, but also to every geophysicist who uses 3D seismic data to retrieve accurate information on the properties of the subsurface. <...>
A velocity model can have enduring and growing interpretive value, beyond its initial creation as a means to optimize the seismic image. The 3D velocity model is often built carefully with a combination of geophysical and geological input, because of the accuracy demands placed on it by the requirements of depth imaging. As such, this model becomes an increasingly effective interpretive tool. This course addresses the ways in which the interpreter should participate in the development of the velocity model, and underscores its interpretive value with numerous case study examples. <...>
This book, Seismic Attribute Mapping of Structure and Stratigraphy, by Satinder Chopra and Kurt J. Marfurt, is designed specihcally as a companion to Marfurt’s 2006 DISC presentation of the same title and is composed primarily of figures from a forthcoming SEG book by the same authors, Seismic Attributes for Prospect Identification and Reservoir Characterization.
Three-dimensional (3D) seismic data have had a substantial impact on the successful exploration and production of hydrocarbons. Although most commonly acquired by the oil and gas exploration industry, these data are starting to be used as a research tool in other Earth sciences disciplines. However despite some innovative new directions of academic investigation, most of the examples of how 3D seismic data have increased our understanding of the structure and stratigraphy of sedimentary basins come from the industry that acquired these data.
Изучение базовых положений сейсморазведки и основных современных методик ин-терпретации, применяющихся с целью качественного и количественного описания строения месторождений нефти и газа.
Рассматриваются статистические задачи и методы их решения в системах пассивной сейсмической локации (ПСЛ), эффективность которых в значительной мере определяется применяемыми методами обработки сигналов. Исследуются основные локационные задачи, такие как обнаружение сейсмически активных объектов, оценивание характеристик движения, определение типа объекта (классификация). Предложенные методы получили свое развитие при работе авторов над реальными проектами по созданию новых систем ПСЛ. Большая роль в развитии статистической теории ПСЛ принадлежит экспериментам, значительная часть которых выполнена на сейсмическом полигоне Новосибирского государственного технического университета.
