Basic Field Processing

Audience

New-hire field processing geophysicists.

Content

The course begins with the basics of signal processing followed by a synopsis of the software used.

The participants create a project and process a simple sequence first using a 2D, and then advancing to a 3D dataset.

The participants become familiar with the field sequence including:

• Loading, understanding data formats and reformatting data when required
• Geometry
• QC of SPS data using the interactive tools
• Trace header update using the geometry information from the SPS data
• Noise attenuation
• Refraction static computation
• Velocity analysis
• Generation of a stack

Interactive applications and techniques are introduced at specific phases during the course to assist with QC of the data.

At each step of the processing, the relevant Quality controls using interactive applications are explained. Identifying potential issues and problems is elaborated on through the use of examples.

The course concludes with a discussion on data analysis and how to create some specific jobs from scratch if required for out of the box problems.
