  • What is Oil and Gas Exploration Seismic Survey?

    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 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 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.

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

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.
