Seismic Interpretation Workshop

Who Should Attend: Geologists, Petrophysicists, Geophysicists, Reservoir Engineers, and Exploration/Production Managers, and technical personnel

Course Summary: Seismic geophysics represents a fundamental tool for both the exploration and development of hydrocarbon resources. This course highlights via an exercise-intensive workshop format aspects of interpretation including uncertainty/risk, and in understanding structure, stratigraphy and fluid/rock discrimination.

Course is designed from an applied standpoint, with numerous exercises and case studies serving to provide critical insight into the use of seismic data in early exploration efforts through later development and reservoir characterization phases. Multiple exercises are used to provide important hands-on learning.

Course Objectives:

• Achieve a better understanding of uncertainty in seismic interpretation
• Achieve a better understanding of structural aspects of seismic interpretation
• Achieve a better understanding of stratigraphic aspects of seismic interpretation
• Achieve a better understanding of rock/fluid aspects of seismic interpretation

Course Content:

• Introduction to Seismic Geophysics—the “need” for seismic interpretation and reservoir analysis, with worldwide case examples illustrating their importance to hydrocarbon production and development.
• Seismic Interpretation Principles—discussion and application of various interpretation techniques and principles as applied to exploration and reservoir characterization, including concepts of structural interpretation (lines/cross-lines, arbitration [user-defined] lines, time slices, visualization techniques, user-tracking versus auto-tracking, etc.), and stratigraphic interpretation (sequence stratigraphy, appearance of key stratigraphic features, texture mapping, etc.). A detailed discussion of display concepts and interpretation procedures/options will be discussed.
• Seismic Attribute Analysis—the fundamental concepts of seismic attributes, including amplitude, phase, and frequency derived attributes, as well as AVA (amplitude versus angle); additional emphasis on specific attributes as related to structure (e.g., coherence, dip displays, derivative, etc.), stratigraphy (horizon slices and windows, amplitude and other attribute extractions, etc.), and reservoir (see below); and shear-wave anisotropy.
• Reservoir Identification and Evaluation—fundamental concepts of reservoir characterization, including attribute analysis and hydrocarbon indicators, fluid analysis, defining reservoir limits, porosity evaluation, net pay, etc.
• Seismic Petrophysics and Data Integration—concepts including extraction of petrophysical information from seismic data, and the integration of well log (including well bore geophysics) and geological analyses to develop coherent reservoir models.
