Advanced Seismic Analysis of Stratigraphic Sequences

Seismic stratigraphy is a powerful tool for exploration and exploitation, especially when the rock-fluid information within the seismic wavelet (reflection character analysis) is integrated with the lithofacies-stratigraphic information, which is determined from reflection group geometry (sequence analysis). The methods used in this course do not rely upon either cosmetic processing or interpretation as an art; instead, practical methods of seismic stratigraphy are employed as a science, based upon firm, tested principles that are applied to a spectrum of tectonic structural styles and depositional environments.

This rigorous, five-day course is a problem-oriented, hands-on workshop including significant group discussion and presentation. Participants learn how to make seismic modeling-interpretation judgments as a basis for seismic-facies and reflection character analysis. Case studies for exploration and development incorporate 2D and 3D seismic data with well data selected from around the world. Each participant should bring a hand-held calculator to class.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

• Evaluate rock-fluid information from wavelet analysis (frequency, velocity, Q. seismic attributes, and AVO)
• Understand the strengths and weaknesses of geovalidation using and misusing synthetics, seismic inversion, and VSP
• Determine fault mechanical stratigraphy through proper interpretation of fault imaging
• Understand the differences, weaknesses, and strengths of both the Vail with the
• Galloway sequence paradigms and when to optimally employ them
• Develop sea level curves from micropaleontology
• Construct detailed seismic facies maps and understand their relationship to Walter's law
• Classify deltas based upon their seismic characteristics
• Differentiate basin floor fan facies and parasequence sets
• Interpret clastic and carbonate depositional system responses to allocyclic and autocyclic processes and the effects upon reservoir architecture and seal potential
• Optimally interpret parasequence set fairways for exploration
• Geophysically characterize reservoirs for optimizing development
