Introduction to Seismic Acquisition and Processing (GPH07)


    Acquisition and processing of seismic data is one of the earliest steps in the oil and gas exploration cycle. Today the industry uses dense 2D seismic grids for early stage reconnaissance of large areas. In later stages operators acquire 3D seismic surveys over specific license areas to define drilling targets and for reservoir characterisation. Later in the field-life repeat seismic surveys serve to monitor changes in the reservoir due to production effects.
    As seismic acquisition is one of the most expensive and operationally complex tasks in exploration, it is of utmost importance to tailor the acquisition parameters to the geologic targets, this way optimising the use of financial resources and to mitigate operational risk.
    Accurate seismic processing is essential to transform raw seismic data recorded in the field to useful information, which is indispensable for reservoir delimitation and characterisation. Therefore the success of any exploration project critically depends on the quality of the seismic data processing applied. During recent years, a large number of processing and imaging algorithms were developed and it is not easy to keep track of the latest developments and to select the right processing steps for the dataset at hand.
    In this course you will learn how to define basic acquisition parameters and you will get a solid foundation of seismic processing principles. We will use wave propagation principles and available geologic information to define survey parameters, which ensure adequate illumination of the exploration targets and optimum signal to noise ratio and imaging of the targets during seismic processing. After the course seismic interpreters will be able to distinguish between real geologic information and processing artefacts. Special focus will be on tendering acquisition and processing projects and processing QC.

    Course Level: Basic to Intermediate
    Instructor: Christian Stotter

    Designed for you, if you are...

    • An operations geophysicist or manager involved in seismic acquisition and processing projects. The acquired knowledge will be useful in the tender process and operational phase of seismic acquisition projects and subsequent processing.
    • A geologist, geophysicist or petroleum engineer, who uses seismic data in daily work and who wants to know about the potential and limitations of seismic data depending on the used acquisition parameters and processing workflows.

    How we build your confidence

    • Attendees will get hands on experience in land and marine survey design using real and synthetic examples
    • The effects of changing key survey parameters will be shown on real data and case studies
    • Basic processing concepts will be derived intuitively from signal processing and wave propagation principles
    • Attendees will get hands on experience in seismic data processing on real data examples
    • Benefits and pitfalls of modern imaging algorithms will be shown on case studies from different geologic environments
    • In a seismic tender exercise participants will define acquisition and processing parameters based on principles they have learned during the course

    The benefits from attending

    At the end of the course you will have a good understanding of the possibilities but also pitfalls and limitations of seismic data acquisition and processing projects. With that foundation you will feel confident to:
