A seismic survey is a non-invasive method of collecting information about the location and characteristics of geological structures beneath Earth's surface. It is widely used to investigate geological properties of the earth and to explore petroleum, natural gas, and mineral deposits. Three phases of seismic survey are data acquisition, processing, and interpretation. Seismic surveys use acoustic waves to create images of the earth through analysis of vibrations from seismic waves. Many methods are used for the initiation of seismic waves, such as dynamite blast, air guns, and seismic vibrator, among others. This technique has replaced the practice of exploding dynamite underground.
Thus, there is an increasing demand for this technology in the oil and gas industry, driving the growth of the seismic survey market. Seismic survey is a method used during the exploration phase of oil and gas development. The method gives a first idea of what is present underneath the earth's surface. This important information is used to create maps to identify areas where gas may accumulate. Currently, almost all oil and gas exploratory wells are preceded by 3-D seismic surveys. Thus, demand for seismic survey is also increasing with a rapid pace around the world. For example, in November 2020, Oil India Limited launched seismic campaign to locate oil and gas in the Mahanadi basin in Odisha.
The company plans to acquire, process, and interpret 1,502 line kilometer (LKM) of 2D seismic data and 1,670 sq. km of 3D seismic data in the five blocks.3-D seismic surveys have lowered finding costs and allowed exploration for reserves not locatable by other means, revolutionizing the industry. This in turn is also expected to accelerate the growth of the seismic survey market in the Asia Pacific region. Seismic survey is a technique of seismic exploration in which the earth's surface is probed by the use of reflected seismic waves for the purpose of determining the structure of the Earth's crust.
Moreover, the seismic survey market can be directly linked to the ever growing demand for seismic technology in shale gas exploration and brownfield projects. Seismic surveys can be carried out onshore and offshore. Offshore surveys are done to find fault lines, underwater volcanoes, earthquakes, ice shelves, underwater caving systems, etc. Inland surveys are usually carried out for determining the location of buried oil and gas deposits, preselling seepage, pre-plate rock formation, fault slip, and fault slip geometry. The cost of such surveys depend upon the size and type of land needed to be surveyed.
Demand for seismic survey has increased in the oil and gas industry due to the aforementioned factors, thereby driving the growth of the seismic survey market.
