1. What Is Seismic Facies Analysis?
Input: Seismic Data (2D or 3D)
Product: Prediction of Rock Types
Sand within reservoir intervals
Shale in overlying seal intervals & source intervals
Seismic Stratigraphic Analysis
Define key stratigraphic intervals
Determine the rock types within each interval
Seismic Sequence Analysis
Seismic Facies Analysis
SLIDE 1
The second part of stratigraphic interpretation focuses in on the prediction of rock types (lithofacies) within key sequences
We start we either 2D or 3D seismic data
We identify and map the major sequence boundaries using reflection terminations
Then we perform what is referred to as seismic facies analysis
Our goal is to predict where we have potential reservoirs capped by potential seals
We may also want to identify regions that have good source rock potential
