Seismic Facies Analysis

Seismic Facies Analysis: A 1-week workshop for mid-level to experienced interpreters

This week long program is designed to function primarily as a workshop. Initial discussions center around a review stratigraphic concepts,  which are then applied to outcrops in the Grand Canyon of Arizona in order to create a number of comparison  sequences and environments recognized in the field with comparative resolution in seismic data.

Delegates will devote specific attention to problems with scale. This is followed by a detailed discussion and definition of seismic facies (reflection configuration, amplitude, frequency, and continuity). All materials is outlined through illustrations from CDP record sections from diverse environments. Participants then apply these ideas to unraveling the geological history of a thermal sag basin with a broad spectrum of environments. Source, seal, and reservoir potential of each unit differentiated are predicted and then compared to well data.

Three main issues are discussed in detail:

• Submarine fans. Seismic facies variations are mapped to predict sand prone intervals. Comparative ideas on modern submarine fans are introduced and utilized.
• Shallow water siliciclastics and the recognition of a variety of systems tracts in the seismic data and the relevant lithofacies predictions. Different models are compared and evaluated. Modern environments are discussed and compared.
• The evolution of a carbonate margin. A variety of carbonate facies and environments are shown and prospected.

In addition to data sets used for interpretation, numerous other seismic lines are used to show comparative environments in other settings. The bottom line for each problem undertaken is to predict drilling locations.
