Abstract

Objectives

  • Identify the three main methods of migration: Kirchhoff, FK, and downward continuation.

  • Estimate migration results with a compass.

  • Understand the principles behind Kirchhoff migration, and recognize the range of algorithms from very simple to complex.

  • Identify the features of FK migration and know how and why the parameters are defined.

  • Recognize the principles of downward continuation migration, distinguish between a time and depth migration, and identify different algorithms.

  • Know the difference between one pass and two-pass 3-D migration algorithms.

  • Recognize that all migration algorithms should be tested.
