Seismic Sequence Stratigraphy Interpretation. Sequence Stratigraphy is a method developed to support geoscientists in the geologic interpretation of subsurface data with the objective of predict play elements presence and quality before drilling. A fundamental principle of sequence stratigraphy is that seismic reflections are produced by contrasts in sonic velocity at chronostratigraphically significant stratal surfaces and unconformities. The method can be applied to 2D and 3D seismic in all depositional environments. The concept of sequence stratigraphy was first developed by Peter Vail in the 1960s.
A fundamental principle of sequence stratigraphy is that seismic reflections are produced by contrasts in sonic velocity at chronostratigraphically significant stratal surfaces and unconformities. To reduce the interpretation time. General seismic data interpretation involves direct fault and horizon mapping sequence stratigraphy and seismic modeling to produce structural stratigraphic and reservoir maps for the delineation exploration and production of hydrocarbon in oil fields. Boundaries are defined on a seismic line by identifying the termination of seismic reflectors at the. Therefore they are considered to approximate time-lines in the sedimentary record. UE Seismic Interpretation and Sequence Stratigraphy.
Seismic investigations provide a vital tool for the delineation of subtle hydrocarbon traps and they are the basis for understanding the regional basin framework and the stratigraphic subdivision.
Sequence stratigraphy of a seismic line across the lower Cretaceous offshore of South Africa. The first two methods operate on stacked and migrated data while the. A seismic cross-section through Little Knife Field tied to a synthetic seismic trace made from a velocity log Williston B asin. General seismic data interpretation involves direct fault and horizon mapping sequence stratigraphy and seismic modeling to produce structural stratigraphic and reservoir maps for the delineation exploration and production of hydrocarbon in oil fields. Seismic sequence stratigraphy therefore can be further subdivided to subunits to analyze a seismic sequence. It is widely used on land and at sea because of its applicability to subsurface.
