Overview

This course is designed to study seismic methods and their applications in the field of petroleum exploration and deals with the three main parts: Acquisition of discrete and three-dimensional seismic information, processing of seismic information and partial interpretation of seismic information (structural, stratigraphic and quantitative).

Intended learning outcomes

By studying the course, the student will be able to:

1. Develops and understands the basic principles, concepts and technical terminology related to signal theory, seismic waves (reflexive and refractive) and analysis of their compounds

2. Understands, describes, evaluates, explains and interprets: Field survey operations (discrete and linear) including the design of the survey program, the devices and equipment used, the recording processes and the acquisition of seismic information (reflexive and refractive)

3. Be able to distinguish the quality of information acquired and processed, and to guess and detect the causes of deficiencies and can be improved by re-analysis and processing.

4. Be able to verify and distinguish the patterns and quality of the final results and understand the usefulness of the interpretation.

Content of the course

The first week

A revitalized review to understand the principles and concepts of reflective and refractive seismic waves, their characteristics, methods of propagation and the laws that govern them. Introduction and general idea on the basics and requirements of terrestrial and marine seismic surveys and the challenges related to survey work in different environments

Second week

Survey of equipment and equipment used in the land and marine seismic survey (power sources, sensors, recording devices), and recovery of the important functions and characteristics of the devices and equipment

Third week

Remote and remote survey operations, land and sea dimensions, study of objectives and preparation of survey programs, recovery of the criteria for determining the factors and dimensions of the stations of the captures and energy sources and their distribution and inspection of the preliminary field records.

The fourth week

Processing of field seismic information, study of components and objectives of processing stages, extensive description of initial processes supported by fullness. Preview samples of field records, verify their quality, analyze and classify their features and content.

The fifth week

A thorough study of the important steps in each stage of treatment supported by several examples and followed by analytical exercises to refine the knowledge gained.

The sixth week

The first half exam

The seventh week

Study some advanced processing processes and supporting mathematical concepts, supported by fullness before and after the operation

The eighth week

Seismic interpretation, understanding the principles and objectives of the branches of seismic interpretation (structural/structural, stratigraphic and quantitative). Preparation of artificial seismology, linking and pumping of artificial lats with the seismic segment. Manual and automated interpretation, hardware and software used, examine and interpret different patterns of automated output.

Ninth and tenth week

Structural interpretation: An extensive study of the rules and the joining of structural interpretation, practical application to seismic segments and segments, including the identification of the types and features of geological structures

Eleventh and twelfth weeks

The second half evaluation

The thirteenth and fourteenth week

Stratigraphic interpretation, an extensive study of goals, systems and mechanisms with practical applications through sycophms and seismic segments.

Fifteenth week

Quantitative, partial interpretation deals with the study of analytical concepts and applications used by seismic features, well records/rock physics, a study of practical cases.

The sixteenth week
