# GP210 - Bob Clapp's Slides

Here you find the presentation slides of classes taught by Bob Clapp during the Fall of 2008.
Most of them are on subjects covered in the textbook but with lots of different diagrams to
help understanding. Two additional presentations introduce subjects covered in 3D-Seismic Imaging
taught by Prof.Biondo Biondi, during the Spring quarter.

**1 ** | You'll be introduced to different **acquisition geometries** exemplified by some data and stacking charts. Moreover, you'll learn the three dimensions of a 2D dataset and have a detailed description of the program synmarine. | chapter1.pdf | | | | |

**2 ** | **Forward and adjoint** operators and the concept of pushing and pulling are explained, using as example the task of writing a program that downward shifts traces. | chapter2.pdf | | | | |

**3 ** | **Waves in Strata** | chapter3.pdf | | | | |

**4 ** | **Normal moveout and stacking** operators are explained. | chapter4.pdf | | | | |

**5 ** | The basic geometry of migrating a dipping reflector is presented. | chapter5.pdf | | | | |

**6 ** | **Waves and Fourier Sum** | chapter6.pdf | | | | |

**7 ** | **Downward continuation of wavefields** is explained and migration of seismic data by downward continuation is introduced with the support of the exploding reflector concept. | chapter7.pdf | | | | |

**9 ** | Quick introduction to **finite-difference migration**. | chapter9.pdf | | | | |

Here you'll find different subjects ranging from the differences between 2D and 3D seismic to time X depth imaging and Kirchhoff X wave-equation migration. | 2dvs3d.pdf | | | | | |

If you are interested on the results of migrating with an **inaccurate velocity model**, take a look at the examples using Marmousi data. | pspi.pdf | | | | | |

Reverse Time Migration | rtm.pdf | | | | | |

Introduction to multiples attenuation | multiple.pdf | | | | | |

Here are two papers explaining the computation of **angle-domain common image gathers** (ADCIGs) and prestack migration using **DSR equation plus split-step correction** (DSR plus split-step). | | | | | | |
