COURSE OVERVIEW:

Geophysical interpretation integrated with well data is the essential process of reconciling indirect seismic measurements with direct physical observations from the borehole. This course provides a comprehensive workflow for tying seismic reflections to geological depth markers, ensuring that structural and stratigraphic interpretations are grounded in physical reality. Participants will explore the mathematical foundations of the synthetic seismogram, learning how to combine sonic and density logs to create a bridge between the time domain of geophysics and the depth domain of geology.

The coverage of this course extends beyond simple horizon picking to include the detailed calibration of seismic amplitudes and phases. Attendees will learn how to extract wavelets from seismic data and use them to improve the match between synthetic traces and real seismic gathers. The curriculum emphasizes the identification of seismic facies through well-log calibration, allowing for more confident predictions of lithology and fluid content in areas away from well control. By integrating high-resolution vertical data with laterally extensive seismic volumes, geoscientists can significantly reduce the risk of structural misinterpretation and depth conversion errors.

In the final stages, the course addresses the use of integrated data for reservoir characterization and quantitative interpretation. Participants will learn how to use well-based rock physics models to interpret seismic AVO (Amplitude Versus Offset) responses and inversion results. This synthesis of data allows for the creation of more accurate reservoir models that honor both the local precision of the well and the regional context of the seismic survey. Through hands-on exercises and case studies, the course provides the technical skills necessary to build a consistent and predictive subsurface framework.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Define the fundamental principles of seismic-to-well integration.
• Construct accurate synthetic seismograms using sonic and density logs.
• Apply check-shot and VSP data to calibrate time-depth relationships.
• Extract and analyze seismic wavelets for improved data matching.
• Identify and correct for stretch and squeeze in synthetic ties.
• Utilize well logs to identify and interpret seismic reflectors.
• Perform multi-well seismic ties to ensure regional consistency.
• Differentiate between primary reflections and multiples using well data.
• Calibrate seismic phase and polarity based on borehole observations.
• Integrate image logs and dipmeters with seismic structural models.
• Use well-based rock physics to interpret seismic inversion results.
• Predict lithology and porosity away from wells using calibrated seismic.
• Analyze the impact of log quality on the accuracy of geophysical ties.
• Develop integrated workflows for prospect maturation and well planning.

TARGET AUDIENCE:

Geophysicists, Geologists, and Petrophysicists who need to calibrate seismic interpretations with borehole data for exploration and development.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
