Common Offset Cubes applied to Velocity Analysis

Audience

Geophysicists who need to pick velocities and mutes from gathers.

Content

Firstly, participants learn to prepare Common Offset Cubes (COFF) cubes, and then load COFF cubes and geometry.

Pick velocity and mutes with the COFF cubes, using maps to select location and QC results, QC stacked data on the fly, smooth velocity in the interpretation toolbox, save velocity and mutes in XPS or ASCII files, and lastly testing and creating COFF cubes on-the-fly are all topics that are covered in this course.

Learning Objectives

  • Understand COFF (Common Offset) cube and generate
  • Load COFF cubes and set up geometry
  • Perform COFF-based velocity analysis using Double Square Root
  • Pick mutes on the gathers
  • QC and save the results using an interpretation toolbox

Duration

1/2-day

Number of Participants

6 - 10

Prerequisites

Participants should have attended: “Use of an Interpretative Workstation and 3D QC”

Software Used

Tornadoi (geovation)

Course Format

Presentations, classroom, exercises
