  • The Magic of Seismic Migration

    This short video explains -- to a non-seismologist -- the concept of seismic migration. Common Midpoint Stack, which was state of the art until the early 1970's, was able to produce seismic images with good signal-to-noise. However, the seismic events tend to be mis-positioned and cross one another, particularly when there is geologic dip. Migration is the process of correcting these dip and positioning errors as an automatic digital procedure. Only the seismic velocity must be known (which, unfortunately, is no small feat in many areas!).

  • Seismic migration - Video Learning - WizScience.com

    "Seismic migration" is the process by which seismic events are geometrically re-located in either space or time to the location the event occurred in the subsurface rather than the location that it was recorded at the surface, thereby creating a more accurate image of the subsurface. This process is necessary to overcome the limitations of geophysical methods imposed by areas of complex geology, such as: faults, salt bodies, folding, etc. Migration moves dipping reflectors to their true subsurface positions and collapses diffractions, resulting in a migrated image that typically has an increased spatial resolution and resolves areas of complex geology much better than non-migrated images. A form of migration is one of the standard data processing techniques for reflection-based geophysi...

A form of migration is one of the standard data processing techniques for reflection-based geophysical methods The need for migration has been understood since the beginnings of seismic exploration and the very first seismic reflection data from 1921 were migrated. Computational migration algorithms have been around for many years but they have only entered wide usage in the past 20 years because they are extremely resource-intensive. Migration can lead to a dramatic uplift in image quality so algorithms are the subject of intense research, both within the geophysical industry as well as academic circles. Seismic waves are elastic waves that propagate through the Earth with a finite velocity, governed by the acoustic properties of the rock in which they are travelling. At an interface between two rock types, with different acoustic impedances, the seismic energy is either refracted, reflected back towards the surface or attenuated by the medium. The reflected energy arrives at the surface and is recorded by geophones that are placed at a known distance away from the source of the waves. When a geophysicist views the recorded energy from the geophone, they know both the travel time and the distance between the source and the receiver, but not the distance down to the reflector. In the simplest geological setting, with a single horizontal reflector, a constant velocity and a source and receiver at the same location , the geophysicist can determine the location of the reflection event by using the relationship: Wiz Science™ is "the" learning channel for children and all ages.

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/Tovex, a specialized air gun or a seismic vibrator, commonly known by the trademark name Vibroseis. Reflection seismology is similar to sonar and echolocation. Refraction seismology is a geophysical principle (refraction) governed by Snell's Law. Used in the fields of engineering geology, geotechnical engineering and exploration geophysics, seismic refraction traverses (seismic lines) are performed using a seismograph(s) and/or geophone(s), in an array and an energy source. The seismic refraction method utilizes the refraction of seismic waves on geologic layers and rock/soil units in order to characterize the subsurface geologic conditions and geologic structure. The methods depend on the fact that seismic waves have differing velocities in different types of soil (or rock): in addition, the waves are refracted when they cross the boundary between different types (or conditions) of soil or rock. The methods enable the general soil types and the approximate depth to strata boundaries, or to bedrock, to be determined. SEISMICS: Seismics are the most important prospecting tool deployed all over the world. The methods work in a manner that may be compared to ultrasound examinations by a doctor, in the sense that ultrasound waves are sent into the body from a transducer probe and are reflected at different intensities by various organs or bones. The ultrasound machine creates an image of the inside of the body from the pattern of reflections detected. With seismic methods, acoustic waves that penetrate into the sea floor are transmitted by airguns on a research ship. The waves travel at different velocities depending on the type of rock they encounter. In the subsurface they are reflected at the boundaries between different rock types. From the specific differences in the sound waves’ travel times, a computer can draw conclusions about the nature of the rock forming the seabed. Just a few decades ago seismic methods could only provide simple cross sections of the sub-bottom. Today modern 3-D seismic methods are employed. These are largely made possible by increasingly powerful computers that are capable of spatially representing bottom structures and reservoirs

This is a social science video that answers - What is earthquake? - How does earthquake occur? - What are the different types of waves? An unexpected movement of the Earth's surface is called an earthquake. When two parts of the earth's surface move suddenly in relation to each other along a fault line, due to tectonic forces, an earthquake occurs. A tremendous amount of energy is released in the form of tremors and vibrations, such earthquakes are called 'Tectonic Earthquakes'. The point of origin of an earthquake is called the 'focus', while the point directly above it, on the surface of the earth is called the 'epicentre'. Owing to the strong vibrations around the point of origin, the degree of destruction is greater around the epicentre. The branch of knowledge that deals with the study of earthquakes is called Seismology, and the experts who study seismic waves are called Seismologists. There are three types of Seismic waves that spread in all directions from the focus. They are the P. S, and L waves. The compressional waves are the first to reach the earthquake recording station as they travel 1.7 times faster than the shear waves and are therefore called 'P' (Primary) waves, while the shear waves are called 'S' (Secondary) waves. The primary waves cause the particles of rock to vibrate forwards and backwards in the direction of the waves. Secondary waves, on the other hand cause the particles to oscillate at right angles to the direction of the waves. When P and S reach the surface of the earth, they get converted into 'L' long waves that travel along the surface, vibrating horizontally at right angles to the direction of the waves called 'Love waves' or Rayleigh waves as they also travel like sea waves. The most violent shocks and subsequent destruction is caused by the L waves. While the S waves cannot pass through liquids, the P waves can pass through any medium. This helped seismologists to learn more about the interiors of the earth. The instrument used to detect and record seismic waves is called a Seismograph. The recorded material appears like a graph and is called a Seismogram. Based on the depth of their foci, earthquakes are classified into tree types. They are: (a) Deep-focus earthquakes that occur at depths exceeding 300 Kms, the reasons for which have not yet been identified. (b) Intermediate focus earthquakes with depths of foci ranging between 55 and 300 Kms. (c) Shallow-focus earthquakes with depths lesser than 55 Kms. The area on the surface of the earth increases along with the increase in depth of the focus, while the intensity increases with the decrease in depth of the focus. To measure the magnitude of the earthquakes, a Richter Scale is used. The point-scale is arranged in such a way that each of the units on the scale is equivalent to 30 times the energy released by the previous unit. While a magnitude of 2 is seldom felt, a magnitude of 7 indicates the lower limit of an earthquake that has a devastating effect over a large area.

Seismic migration is the process by which seismic events are geometrically re-located in either space or time to the location the event occurred in the subsurface rather than the location that it was recorded at the surface, thereby creating a more accurate image of the subsurface. This process is necessary to overcome the limitations of geophysical methods imposed by areas of complex geology, such as: faults, salt bodies, folding, etc. Migration moves dipping reflectors to their true subsurface positions and collapses diffractions, resulting in a migrated image that typically has an increased spatial resolution and resolves areas of complex geology much better than non-migrated images. A form of migration is one of the standard data processing techniques for reflection-based geophysical methods This video is targeted to blind users.
