КРАТКИЙ КУРС ОТМЕНЁН В СВЯЗИ С НЕДОБОРОМ ГРУППЫ

Краткое описание курса

Морская донная сейсморазведка (OBS) находит всё более широкое применение. Размещение приёмников на дне моря позволяет регистрировать и продольные, и поперечные волны, при этом разделение источников и приёмников позволяет получать полноазимутные изображения. Особенности морской донной сейсморазведки создают некоторые проблемы, которые необходимо решать при проектировании и выполнении съёмки, при обработке и интерпретации данных, построении изображений. Успешное применение этой технологии будет продемонстрировано на ряде примеров.

Краткий курс будет прочитан на английском языке без перевода.

TITLE: Understanding Ocean Bottom Seismic

Course Description

The use of Ocean Bottom Seismic (OBS) is increasingly more utilized. The placement of receivers on the sea floor, allows for measurement of both pressure and shear waves, while the decoupling of source effort from receiver effort allows for full azimuth imaging. The characteristics of OBS creates challenges, which need to be addressed in survey design, acquisition, processing, imaging and interpretation. Through examples, successful use of this technology will be demonstrated. The course will describe the characteristics of the wavefields, which can be acquired, and how they can be used practically in an E&P setting. Next survey design will describe how to capture the different wavefields, while a look at the different acquisition techniques will attempt to demistify acquiring OBS data. OBS data, due to the different wavefields acquired, requires more care in processing, so the course will look at key areas in processing and how they differ from conventional marine processing. Finally through a series of case studies, the successful application of OBS will be demonstrated.

Course outline

  • Describe the characteristics of ocean bottom seismic

  • Insights into survey planning

  • Differences in acquisition technologies

  • Review the key technologies to process and image ocean bottom seismic

  • Through examples, show successful use of the technology

Course Objective

The objective of this one-day course is to provide the attending geoscientists an insight into the key issues which are typical to OBS. These insights will enable the geoscientists to succesfully adopt this technology in their daily work.

Participants' Profile

The course is designed for geoscientists, with subsurface problems, which require the adoption of innovative geophysical solutions
