  • 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!).

  • How does Earthquake occur with explanation - Social Science 3D animation video in HD

    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 s...

  • 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.

This month, the Bureau of Ocean Energy Management (BOEM) is preparing an environmental impact statement (EIS) on seismic testing's potential expansion into the Mid and South Atlantic, and its recommendations will reach the White House. BOEM needs to consider the latest and best science on seismic, which exposes its many risks. Share the truth about seismic blasting and increase awareness about this deadly practice!

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 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.

At SIPES 2013 Annual Meeting, Deborah Sacrey, Consulting Geophysicist, discusses a case study involved a newly acquired 3D seismic volume in a fringe area of the Eagle Ford Shale Trend resource outline. The Self Organizing Map (SOM) analysis proved to be complementary to the interpretation of the data. The application of using SOM analysis in Paradise using selected seismic attributes can dramatically reduce uncertainty and thus decrease exploration risk in unconventional reservoirs. Transcription Summary: This afternoon we're going to talk about a new software I've been working on for the past couple years that was started by Tom Smith. The software involves unsupervised neural analysis using seismic attributes and trying to find anomalies in seismic data. What I want to talk about today, is Self-Organizing Maps (SOM). A SOM is a type of artificial neural network that trains without supervision on unclassified data to produce a map. Now people are not as familiar with unsupervised maps as they are supervised maps. Stratimagic is a supervised neural analysis where you have known well data. There is a good well and a bad well, and you want it to map the changes in the seismic waveform between the good well and the map well at the bad well. It will give you a map channel that can be mapped. This is an example of supervised neural networks. What we're doing is unsupervised. This first example is from Kahonen's book on unsupervised neural analysis. He put together 39 attributes, much like we would look at attributes in seismic data, which represent the quality of life issues around most countries in the world. Using a nine by thirteen hexagonal neuron topology he completed the neuron analysis. This created interesting results based on how the countries with very similar attributed tended to line up. The key elements here are self-organizing maps, neural maps, and anomalies. The important thing about an anomaly is that we're looking for probability of fit and when you have something as anomalous it has a very low probability. You have a neuron out there that's looking for something different in the seismic attributes from every other part of the seismic data. When we run a SOM analysis on seismic data we end up with two new volumes. One is called a classification volume, the other is called a probability volume. That's where we see our anomalies and that's where we can highlight them and use them. Using the SOM neural analysis we can take three different attributes and apply them to 200 data points. You can view this in the 2D or the 3D viewer. While that is training, we will run through ten different epochs. The epochs are the training process. The neurons go through the data ten different times and they're going to analyze the different data points. Each epic starts to slow down as it goes through the training process. They start figuring out which of the data points they're going to attach themselves to. The attribute analysis brings out information in the data that you wouldn't necessarily see if you just looked at each attribute on its own. You're looking for an analysis that can probably help reduce the risk in type 2 and type 3 reservoirs. In the software, we have a 2D and 1D color bar and we can isolate the data in the 3D viewer by selecting certain neurons. The more data we work with, the more tests we do, the more we're learning there are anomalies in the low probability. When you put a combination of neurons together sometimes you can highlight channel sequences, and sometimes you can gain strati-graphic information that may not be hydrocarbon bearing but may impact what you're looking for in the area. The next thing we're working on is Principal Component Analysis (PCA). Principal Component Analysis helps you to find the attributes that make the most impact in your interpretation. Neural analysis can be done on 2D or 3D data while a Principal Component Analysis, if you have lots of attributes going in, will save you time and possibly give you better results. One example involves Repsol data in offshore Gianna. We used a specific set of analysis for the Repsol data employing curvature and similarity. These are specialized volumes that we run in the software. When you put in the 3D volume and isolate it, you make certain neurons transparent, and we knew exactly where they hit pressure. There was something that their geophysicists and their engineers could not see in the regular data that we were able to pull out using the SOM analysis. The more information you have for the wells and production, the better the solution could be to specific attribute selections. In conclusion unsupervised neural networks analysis or SOM maps can solve a lot of problems. They can analyze the attributes to reduce risk and identify specific solutions.

The ocean is a world of sound. Seismic airgun testing, a method of searching for offshore oil and gas, threatens to turn that world upside down. Seismic blasts can injure or kill marine life, threaten the health of regional fisheries, and risk the jobs of those who depend on the ocean for their livelihood. This month, the Bureau of Ocean Energy Management (BOEM) is preparing an environmental impact statement (EIS) on seismic testing's potential expansion into the Mid and South Atlantic, and its recommendations will reach the White House. BOEM needs to consider the latest and best science on seismic, which exposes its many risks. Share the truth about seismic blasting and increase awareness about this deadly practice!
