Abstract
The main objective of exploration seismology is obtaining structural subsurface information that may indicate possible hydrocarbon reservoir after proper interpretation. Reflection seismic survey is a dominated method for determining the subsurface structure during hydrocarbon exploration. Sedimentary layers have faults, anticlines, folds, and unconformities which are in fact the very features that trap petroleum are the targets of the seismic exploration program in the first place. Most important physical parameter method for determining an accurate image of the subsurface, is velocity of the geological medium. Thus the velocity depends on the subsurface, its physical state ( whether solid, liquid, or gas). Howevere, it is not that easy to obtain a good velocity model. This is often an iterative process. This paper will be concentrated on one of three major techniques of seismic processing is namelly Normal moveout ( NMO ), which is one of the cores of the stack technique. The procedure for eliminating the effcet of offset to the traveling time of reflected wave. The using data is 2d model case.
