This course provides a practical introduction to the use of geophysical, and especially seismic, data for reservoir characterisation. It focuses on understanding the logic, underpinning assumptions, and limitations of seismically derived information, and on how to select and apply seismic attributes to address specific reservoir characterisation tasks.

Participants will learn how to link well and seismic information, analyse and validate seismic attributes, and understand the principles of AVO and fluid replacement analysis at a practical level. The course also introduces seismic inversion, the use of inversion results in reservoir characterisation, and workflows for integrating seismic attributes with geological, petrophysical, and engineering data in reservoir models. Emphasis is placed on data integration, quality control, and realistic expectations of what seismic can and cannot resolve at the reservoir scale.

COURSE OBJECTIVES:

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

• Explain the logic, underpinning assumptions, and main limitations of seismically derived information for reservoir characterisation.
• Describe the main classes of seismic attributes and their typical applications in structural and reservoir interpretation.
• Select appropriate seismic attributes for specific tasks such as structural mapping, lithology discrimination, and fluid indication.
• Link well data and seismic data through time to depth relationships, wavelet estimation, and synthetic seismograms at a conceptual level.
• Perform basic attribute analysis and validation, including correlation with well data and cross-plotting for quality control.
• Describe the principles of AVO (amplitude variation with offset) and fluid replacement analysis, and their use as qualitative fluid indicators.
• Explain the basic concepts of seismic inversion and how inversion results (for example, impedance volumes) are used in reservoir characterisation.
• Understand workflows for integrating seismic attributes and inversion results into reservoir modelling.
• Recognise the benefits and challenges of data integration across seismic, geological, petrophysical, and engineering domains.
• Identify key sources of uncertainty in geophysical reservoir characterisation and describe simple approaches to manage them.

TARGET AUDIENCE:

• Geoscientists
• Geophysicists involved in exploration, appraisal, or development
• Development and reservoir geologists working with seismic-derived properties
• Reservoir engineers who use geophysical inputs in reservoir models and field studies
• Petrophysicists supporting rock property and seismic calibration
• Subsurface professionals involved in integrated asset and field development teams

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures and discussion sessions, as well as case studies, will be managed to maximise the amount and quality of information, knowledge, and experience transfer. 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 learning. 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.
