Course Content
This e-symposium presentation places the interpretation of deep-water turbidites discernible in 3-D seismic inversion data within a geological context. It will include multiple case studies, four of which are located in the Gulf of Guinea (one Pliocene plus Cretaceous examples). One such case study (undisclosed location) features a reservoir characterization technique that facilitates calibration of elastic attributes to sand. The remainder of the workshop will focus on interpretation of seismic anomalies to predict prevailing fluid type(s). This tutorial will also offer suggestions for visualization of quantitative results.
Specific aspects to be covered include the following:
- Integrated analysis of geophysical data
- Challenges in interpreting deep-water turbidites
- Pitfalls
- Seismic Data Conditioning: Why conditioning of seismic amplitude data matters - taking a quick look at your gathers, stacks and attributes
- Types of 3-D seismic inversion techniques
- Calibrating elastic attributes to reservoir sand
- Techniques for placing attributes from simultaneous inversion into a viable geological context
- Example 1: Gulf of Guinea (Pliocene)
- Example 2: Gulf of Guinea (Cretaceous): Joint interpretation of impedances
- Example 3: Gulf of Guinea (Cretaceous): QI using Fundamental Statistics
- Example 4: Gulf of Guinea (Cretaceous):
- a. Elastic data versus compaction effect;
- b. Quantitative interpretation using rock physics;
- c. Facies classification
Structure of the E-Symposium
Each e-symposium consists of one-hour live e-symposium, along with material for one full day of independent study. The live portion will be followed by a full day of independent study (not a live event). The one-hour live e-symposium can be accessed from any computer anywhere in the world using a high-speed internet connection. After the event is over, you will receive via email information about accessing the asynchronous segment (not live) which consists of your independent study materials, to be accessed and studied at any time. You will be able to email responses to the readings, along with your study question answers for CEU credit (if you sign up for the extended package).
