This book on High Resolution 2D and 3D seismic reflection touches on the fundamentals of high resolution seismic reflection in the area of data acquisition, processing and interpretation. It is a book written out of field experience, with practical examples that will guide young seismologist who want to build career on seismology. The preliminary theoretical background developed from so many research works will be of tremendous help for researchers who have little knowledge on seismology. The uniqueness of this book is that, it gives insight to what it takes to process and interpret high resolution seismic reflection data acquired in the basement complex terrain, different from the usual exploration data acquired in the sedimentary terrain. It also highlight on the principle and application of AVO analysis with practical field examples.
