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

Estimated Time

53 minutes of video lectures

AAPG

Since its founding in 1917, the American Association of Petroleum Geologists has been a pillar of the worldwide scientific community. The original purpose of AAPG, to foster scientific research, to advance the science of geology, to promote technology, and to inspire high professional conduct, still guides the Association today.

AAPG provides publications, conferences, and educational opportunities to geoscientists and disseminates the most current geological information available to the general public.

As the world's premier professional association for explorationists, AAPG is about the science of petroleum geology.

It's also about the people.

AAPG's membership is made up of more than 40,000 members in 129 countries in the upstream energy industry who collaborate – and compete – to provide the means for humankind to thrive.

AAPG provides the network of communications that allow those professionals to succeed.

We invite you to see who we are, what we are about and to contact us for membership information or details about the many services we provide.
