The applicant should indicate that the purpose of the project is for seismic surveying or geophysical exploration and refer to the Seismic Exploratory Operations Survey General Permit Example Project Description document (or other project description) and include any other project-specific information. Methods of petroleum exploration and production (E&P) typically involve expensive, technologically driven approaches. It can be used to derive important details about the geometry of structures and their physical properties. Drilling exploratory wells is also an expensive Seismic exploration primarily makes use of compressional waves (P waves), whose velocities in rocks range from 0.4–0.5 to 7–8 km/sec. Seismic MethodSeismic prospecting has become the most valuable technique to reduce exploration risk of being unsuccessful in locating a prospect. All aspects of seismic acquisition are then described. HANDBOOK OF GEOPHYSICAL EXPLORATION SEISMIC EXPLORATION Editors: 75% of worldwide seismic exploration activity comprised 3-D seismic surveys (Society of Exploration Geophysicists, 1996; 1997). This velocity Seismic survey is the geophysical method that provides the most detailed picture of subsurface geology. <> Shear waves (S waves) are rarely used because of the difficulty in exciting them; the velocities of S waves range from 0.1 to 5 km/sec. Seismic prospecting has become the most valuable technique to reduce exploration risk of being unsuccessful in locating a prospect. The seismic exploration phase is a very important to the exploration activities, because this is the most precise way to approximate where the oil might be, thus enabling to cut down on wrong location drilling. • Governments and the private sector have used this method of exploration in the U.S. and around the world for over 40 years. %�� About this page.

Seismic Interpretation The basic principle of seismic data acquisition is that, man-made seismic waves are just sound waves (also called acoustic waves) with frequencies typically ranging from 5 HZ to just over 100 HZ. About this page. �-�D�)%JbX�5R. Making sense of the seismic image, identifying and mapping geological structures that can act as oil traps is the final stage of the seismic process. All aspects of seismic acquisition are then described. • Seismic exploration is divided into refraction and reflection surveys, depending on whether the predominant portion of the seismic waves’ travel is horizontal or vertical. Seismic profile with interpretation of horizons and structures 4.
