Given a reasonably noise-free response, seismic wavelength limits the detail which can be seen in two dimensions: vertical, or the thickness of Stratigraphic units; and horizontal, or the areal size of features. Most reflection events seen on a seismic section are composites of reflections from individual interfaces. Seismic stratigraphy in the 1970s introduced a revised definition for the concept of sequence: that is, ‘a relatively conformable succession of genetically related strata bounded by unconformities or their correlative conformities’ (Fig. Introduction to Seismic Stratigraphy: A Basin Scale Regional Exploration Workshop - ISS. ���2��,d��)��\�t"���3����� ��B���+��AR2���_qV4&�^q�������W�Ņ��3Kx/

In this rigorous workshop, participants pragmatically apply the seismic stratigraphic method to optimizing their exploration efforts by working in teams on projects selected from diverse settings around the world. The principles of seismic stratigraphy are briefly explained in section 4.2, including the recognition of seismic facies. 1.Seismic Seismology: Study of earthquakes and the structure of earth on the basis of characteristics of seismic waves. Seismic stratigraphy analyzes the geological concepts of stratigraphy by identifying the seismic reflection termination patterns that may record stratal terminations such as onlaps, downlaps, erosional truncations, and toplaps. January 01, 1977. Furthermore, it can provide a predictive model extrapolated beyond the borehole as to aspects of the quality of potential reservoirs and seals, their sedimentary environments of deposition, and in some cases, even their paragenesis. Seismic stratigraphy techniques help us for stratigraphic interpretation of seismic reflectors.
