Course description

This course will provide information related to recent trends and advances in land seismic data acquisition technology, equipment and the methodologies that are being utilized to improve seismic imaging quality and productivity of 3D acquisition with an emphasize on the high-end surveys as performed in open areas. The course will not cover the fundamentals of 3D and multicomponent seismic survey design, although there will be a section that will give a review of recent survey design approaches and principles.


Course objectives

The purpose of this course is to:

  • provide an overview of trends in 3D land seismic and achievements;
  • understand trade-offs in modern field technologies;
  • understand the ways to improve seismic imaging and data conditioning for better reservoir characterization.


Course outline

  1. Introduction
    The revolutions and trends in 3D land seismic and evolution in survey design, field equipment, and acquisition techniques. The criteria of field data quality. The role of global positioning systems.
  2. Arrays versus point receivers and point sources
    Intra-array statics (synthetic and field-data examples), non-vertical ray emergence, and other factors degrading high-frequency content of acquired data and distorting amplitudes and AVO effects. Is there a compromise between high-frequency preservation and S/N ratio improvement? Digital array forming.
  3. Wide-azimuth and high-density surveys
    Breakthrough in seismic imaging with HD and WAZ data. More receivers or more sources? New types of attributes extracted from HD and WAZ data to better characterize complex and fractured reservoirs.
  4. Excitation and recording of wideband seismic signals
    Why do we need broadband signals? Types of velocimeters and accelerometers. Low-dwell and other nonlinear sweeps. Field data examples.
  5. 3C sensors and multi-component seismic
    Advantages of 3C single sensors from operational and geophysical points of view. Multicomponent seismic with MEMS accelerometers: expectations and practical achievements. Ray-tracing and finite-difference modeling studies.
  6. Multiple-fleet and high-productivity vibroseis techniques
    New paradigm in seismic exploration: better sampling of noise and signal. The issues of data and equipment QC in high-productivity vibroseis.
  7. Diversity stack in noisy areas
  8. Cableless recording systems
    Innovative technologies enabling a new generation of recording systems without cables and radio: the importance of GPS in the evolution of land seismic acquisition techniques. Where cableless systems are applicable? Full cableless and infill modes. Testing of autonomous (nodal) and real-time recording systems in Russia.
  9. Conclusions
    Not all acquisition techniques are equal (status in Russia vs. Middle East and North America)
    What will be high-end land 3D surveys in the future: point 3C acquisition? A mix of cable and cableless, very dense and very noisy data?


Participants' profile

The course is appropriate not only for geophysicists involved in land survey design, acquisition, and modeling, but also for those involved in data processing and interpretation who wish to better understand the potential improvements that can be made.



The course assumes familiarity with basic seismic acquisition techniques and equipment. No mathematical background is required, since physical concepts are graphically illustrated. A comprehensive list of references is given in the book.

Integrated Seismic Acquisition and Processing

Instructor: Mr Jack Bouska (Independent Consultant)

This course covers modern techniques in 3D seismic acquisition, from the perspective of seismic as an integrated system comprising: acquisition design, field operations, data processing, imaging, and interpretation. This one day course will review the basics of 3D survey design, with emphasis on how practical aspects of interpretation, data processing, imaging and/or field operations can either constrain.

Seismic Acquisition Project Essentials: from Concept to Completion and Beyond

Instructor: Mr Jan de Bruin (Project Manager - Seismic Acquisition)

Existing courses and books with the title `seismic acquisition' typically deal with designing seismic surveys. Although I treat design in a somewhat less conventional way, it is an important part of this course too, but other equally important subjects receive equal attention. These are: Clients, Finance, Procurement, Scouting, Communities, Execution, Equipment, HSE and Project Management. Any serious flaws in either of these can make a seismic survey less successful or fail altogether. Although these elements have nothing to do with Geophysics, they are essential ingredients of Seismic Acquisition. The course will look at all this from the perspective of seismic companies as well as oil companies

The Benefit of Broadband Technology for Reservoir Characterization and Imaging – the End-User Value

Instructor: Dr Cyrille Reiser (Petroleum Geo-Services)

The main aim of this course is to provide a very accessible overview of the many concepts behind broadband seismic (primarily offshore) and its implication for the reservoir focused asset based geoscientist. This will be done through the a very comprehensive set of case study material from all regions of the world and for various stages of the exploration, appraisal and development asset life cycle. The course aims to objectively discuss the various broadband seismic technologies and commercial offerings available today and their respective merits with regards to quantitative reservoir characterization and reservoir imaging using real world application examples. The course will further attempt to identify possible pitfalls and issues with regards to the treatment of broadband data that might lead to flawed or erroneous QI.

Broadband Technology

Instructor: Dr Robert Soubaras (CGG)

This one-day course is intended to explain how, by combining advances in equipment, acquisition design and processing, the bandwidth of marine seismic images has been increased recently from 3 to 6 octaves. The course starts with a theoretical part that provides a unified framework allowing to cover the theory of the various marine broadband methods that are currently used (over-under, dual sensor, variable-depth), with the aid of synthetic examples as well as real data results based on the variable-depth streamer method. After the specific receiver deghostings are addressed, other processing steps that have to be adapted to broadband data are described.

Time-Lapse Seismic: A Multidisciplinary Tool for Effective Reservoir Management

Instructor: Mr Cedric Fayemendy (Statoil)

Geophysical Reservoir Monitoring (GRM) of reservoirs relies on frequent time-lapse observations with high-survey repeatability. This technology is a key enabler for maximizing the oil recovery of oil and gas fields. The GRM technology aims at understanding and updating the knowledge of producing reservoirs. This is achieved through mapping the movement of fluid and pressure fronts and fluid contacts during production and injection. The combination of production monitoring with repeated seismic acquisition and geological and reservoir information provides reliable estimates of static and dynamic reservoir parameters. The lecture will first review the geophysical reservoir monitoring history at Statoil. We will share our experience with 4D processes, resources allocation and the overall monitoring strategy. The lecture will also cover challenges in understanding the 4D responses and value creation. Finally, we will look at how we push the GRM technology towards higher use of quantitative results.

Land Integrated Survey Design

Instructor: Mr Paul Ras (SD2I Geophysical Consulting)

Several significant land seismic acquisition technology advances have emerged in the last decade: high-channel count single sensor (point receiver), simultaneous source high-productivity vibroseis, broadband and wireless nodal systems. To get the most out of these new technologies, the survey design process has been evolving as well and now includes single sensor, single source, simultaneous source, broadband, symmetric sampling, cross-spreads, spatial continuity and more powerful 5D interpolation methods. This course presents an integrated approach to modern land 3D seismic survey design as it has a key role in the seismic value chain going from acquisition to processing, imaging and inversion & characterization.
