Historically, seismic exploration would leave cleared lines in the forest up to eight metres wide for lengths that could stretch many kilometres. 11.15.6.2 Land-Based Seismic Methods in Mineral Exploration. Of all the geophysical exploration methods, seismic surveying is unequivocally the most important, primarily because it is capable of detecting large-scale to small-scale subsurface features. 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. 75% of worldwide seismic exploration activity comprised 3-D seismic surveys (Society of Exploration Geophysicists, 1996; 1997). Drilling exploratory wells is also an expensive 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. It can be used to derive important details about the geometry of structures and their physical properties. The popu-larity of 3-D seismic methods for hydrocarbon exploration can be attributed to simple economics: its use has significantly reduced explo-ration costs by reducing the number of dry holes drilled (Greenlee et al., #020: Transforming Seismic Exploration to Approach Zero Land Disturbance 4 reflected by subsurface geological formations and recorded at the surface using portable recording equipment called geophones.

Enwenode Onajite, in Seismic Data Analysis Techniques in Hydrocarbon Exploration, 2014. Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves.The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic vibrator, commonly known by the trademark name Vibroseis. �����ڜ���Hg�}�%�o�(�����;��=����/=U�����_���kz��(�]��_��o�&�ʺ����I����#8��q�������2��Jxy��|y�o��z�\ bs*8�#�K�}�tIX�9���t�UV�Ȱ*��\ H�E���E�;�3����5 23�P�Y�-�)�"k���\5�p�9�Z�+Yp��k����=Y� "8&f��-��l����e�*�Q�����Ȱ�u������lS�A)ΙW • Seismic exploration is divided into refraction and reflection surveys, depending on whether the predominant portion of the seismic waves’ travel is horizontal or vertical. stream • Governments and the private sector have used this method of exploration in the U.S. and around the world for over 40 years.
