Seismic prospecting consists of three separate stages: data acquisition, data processing, and data interpretation The success of a seismic prospecting operation depends on satisfactory completion of all three stag The seismic energy recorded by each seismic receiver during the data acquisition stage is known as a "seismic data trace"...

Coal mining

Coal mining - Coal mining - Prospecting and exploration: The fundamental objective of coal prospecting is to discover coal resources through a search In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam Once a seam has been discovered, considerable further work is ....

Interpreting seismic amplitudes (Chapter 5)

In principle this process can also be used to interpret amplitudes on 2-D seismic data, but as we saw in chapter 1 the power of 3-D seismic lies in the ability to make maps based on very densely sampled data, allowing us to see systematic amplitude changes that are only just above the noise level...

Geologic modelling

Geologic modelling, geological modelling or geomodelling is the applied science of creating computerized representations of portions of the Earth's crust based on geophysical and geological observations made on and below the Earth surface A geomodel is the numerical equivalent of a three-dimensional geological map complemented by a description of physical quantities in the domain of ,...

Seismic signal processing

Abstract: Seismic prospecting for oil and gas has undergone a digital revolution during the past decade Most stages of the exploration process have been affected: the acquisition of data, the reduction of this data in preparation for signal processing, the design of digital filters to detect primary echoes (reflections) from buried interfaces, and the development of technology to extract from ....
