Seismic Interpretation and Beyond …
Develop a Geologic Framework
Apply the Geologic Framework to Prospecting (Exploration)
Given our time constraints, we will only be able to look at a subset of the concepts, procedures
and tools that geologist and geophysicists use in the exploration phase of the oil & gas industry

Workflow: Overview
1. Geologic Framework
2. Data Analysis
3. Prospect Elements
4. Prospect Assessment
We can subdivide the exploration work process
from seismic interpretation forward into 4 major elements
Modules 8 - 12 provide some details on each
of these basic elements

Geologic Framework
Structural InterpretationStructural Interpretation• Faults & Folds
• Subsidence & Uplift
• Structural Trends
• Structural Features
Stratigraphic InterpretationStratigraphic Interpretation• Unconformities
• Stratal Packages
• Environments / Facies / Lithologies
• Ages
Using all available data (wells, seismic, outcrop, regional studies, gravity, magnetics, etc.) build
a framework of present-day structure and stratigraphy

Applying the Framework for Prospecting
1.Data Analysis• Present-day conditions - How things are now
• Basin reconstruction - How things evolved
2.Prospect Elements• Individual elements: Source, Migration,
Reservoir, Trap, Seal
• Favorable juxtaposition of all elements
3.Prospect Assessment• Likely HC volumes in the success case
• Risking - How likely is the success case?

Alpha Beta
For Modules 12 through 14, we use two hypothetical leads: Alpha and Beta. Should we propose that we drill either or
both?
