Modern seismic reflection surveys are designed and acquired in such a way that the same point on the subsurface is sampled multiple times, with each sample having a different source and receiver location. The seismic data is then carefully processed to preserve seismic amplitudes and accurately determine the spatial coordinates of each sample.
Seismic data acquisition is the first of the three distinct stages of seismic exploration, the other two being seismic data processing and seismic interpretation. [1] Seismic acquisition requires the use of a seismic source at specified locations for a seismic survey, and the energy that travels within the subsurface as seismic waves generated ...
The following books cover important topics in reflection seismology. Most require some knowledge of mathematics, geology, and/or physics at the university level or above. Brown, Alistair R. (2004). Interpretation of three-dimensional seismic data (sixth ed.). Society of Exploration Geophysicists and American Association of Petroleum Geologists.
Seismic, well logs and other input data are each represented as a probability density function (PDF), which provides a geostatistical description based on histograms and variograms. Together these define the chances of a particular value at a particular location, and the expected geological scale and composition throughout the modeled area.
Anderson's fault theory also presents a model for seismic interpretation. [7] This model predicts the dip of faults according to their regime classification. [2] Conjugate walls in any fault will share a dip angle with that angle being measured from the top of the hanging wall or the bottom of the foot wall. [2]
In reflection seismology, a seismic attribute is a quantity extracted or derived from seismic data that can be analysed in order to enhance information that might be more subtle in a traditional seismic image, leading to a better geological or geophysical interpretation of the data. [1] Examples of seismic attributes can include measured time ...
Nigel Allister Anstey (born 1927) [1] is a British geophysicist who has made major contributions to seismic exploration, which are the foundations for many of the techniques used in today's oil and gas exploration. Anstey's contributions impact every major area of seismic exploration -– from seismic acquisition to seismic processing to ...
Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design , earthquake engineering or structural assessment and retrofit (see structural engineering ) in regions where earthquakes are prevalent.
