While he was a senior scientist at Exxon he come up with three core concepts that define sequence stratigraphy. To reduce the interpretation time.
Sequence stratigraphy of a seismic line across the lower Cretaceous offshore of South Africa.
Seismic sequence stratigraphy interpretation. In other words seismic stratigraphy involves the interpretation of seismic reflection data by extracting geologic and stratigraphic information Lin 1977. Seismic sequence stratigraphy therefore can be further subdivided to subunits to analyze a seismic sequence. This page is the first step of a seismic stratigraphy interpretation.
Its objective is to define the genetic reflection packages that envelope seismic sequences and systems tracts. These bounding discontinuities are identified on the basis of reflection termination patterns and their continuity. Boundaries are defined on a seismic line by identifying the termination of seismic reflectors at the.
Sequence Straigraphy is the study of rock units within a chronostratigrphic framework bounded by erosional surfaces nondeposition or conformities. The concept of sequence stratigraphy was first developed by Peter Vail in the 1960s. While he was a senior scientist at Exxon he come up with three core concepts that define sequence stratigraphy.
A fundamental principle of sequence stratigraphy is that seismic reflections are produced by contrasts in sonic velocity at chronostratigraphically significant stratal surfaces and unconformities. Therefore they are considered to approximate time-lines in the sedimentary record. 2 Exercise 1- Tying a Well Synthetic to a Seismic Line.

Seismic stratigraphic analysis is based on identification and correlation of the sequence-bounding surfaces on seismic reflection profiles. This process is a time-consuming and tedious task that involves identification of individual boundaries on 2D seismic profiles and their correlation with each other to produce 3D sequence models. To reduce the interpretation time.
Stratigraphy Stratigraphy is a branch of geology which studies rock layers strata and layering stratification. Seismic Stratigraphy The study of seismic data for the purpose of extracting stratigraphic information is called seismic stratigraphy. It is widely used on land and at sea because of its applicability to subsurface.
DGB offers complete seismic sequence stratigraphic interpretation studies that include. Wheeler transformed seismic data 2D and 3D Full systems tracts interpretations. Attributes analysis for visualization of Paleo-geomorphological features.
Stratigraphic Interpretation using Seismic Attribute Analysis Seismic Facies Classification. Geophysics is applied to societal needs such as mineral resources mitigation of natural hazards and environmental protection. 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.
Seismic stratigraphy combines two very different scales of observation. The seismic and well control. The systematic approach applied in seismic stratigraphy explains why many workers are using the.
Sequence Stratigraphy is a method developed to support geoscientists in the geologic interpretation of subsurface data with the objective of predicting play elements presence and quality before drilling. The method can be applied to 2D and 3D seismic in all depositional environments. 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.
The first two methods operate on stacked and migrated data while the. 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. The method can be applied to cores well logs seismic lines 2-D and 3-D and outcrops and in all depositional environments.
