Advanced Seismic Stratigraphy: A Sequence-Wavelet Analysis Exploration-Exploitation Workshop - ADS

Petroskills Registerbutton

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 workshop 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 2-D and 3-D seismic data with well data selected from around the world. Each participant should bring a hand-held calculator to class.

Geophysicists, geologists, and explorationists who have completed the PetroSkills course, Introduction to Seismic Stratigraphy: An Exploration Workshop: A Basin Scale Regional Workshop, or have comparable training and desire a challenging workshop, which will improve exploration and development skills.

You will Learn:

Participants will learn how to:

  • Evaluate rock-fluid information from wavelet analysis (frequency, velocity, Q. seismic attributes, and AVO)
  • Understand the strengths and weaknesses of Geovalidation using and miss-using 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
