3D SEISMIC ATTRIBUTES

 

Location: London, UK.

 

Course Dates: March 25-29, 2019

 

Instructor: Prof. Jose Regueiro S., Ph.D., Colorado School of Mines / Geophysicist / Professor / Consultant / Instructor.

 

Who should attend:

This course is intended for geophysicists, geologists, and reservoir engineers, with some basic knowledge of the seismic reflection method.

 

 

 

Course Objective:

To describe the so-called Seismic Attributes, as well as their applications in the processes of 3D Seismic Data interpretation, emphasizing the utility of this type of information during the phases of exploration and/or reservoir characterization.

 

Duration: 24 hrs. (theory and examples) + 16 Hrs. workshop

 

Introduction

History and Classification of Seismic Attributes

Review of Basic Concepts of Seismic Wave Propagation

Brief Aspects of Seismic Data Acquisition and Processing

Color Display and 3D Visualization

Time Attributes

Amplitude Attributes

Complex Trace Attributes – Hilbert

Spectral Decomposition

Other Spectral Attributes

Geometrical - Structural Attributes

Seismic Fracture Analysis

"Seismic Energy" (detuning)

Textural Attributes

Multi-Attribute Facies Classification

Multi-Attribute Properties Estimation

 

 

Course benefits;

At the end of this course, the participants should we able to apply 3D Seismic Attribute Analysis, and extract from them important information, which should help in identifying structural, stratigraphic, and rock/fluid parameters associated with their reservoirs. They should be capable of making decisions concerning the use of the results, coming from these types of information, in the evaluation and prognosis of the reservoirs models under their responsibility.
