Quick Guide: How to Find Subsea Oil and Gas Seismic Companies?
Collection of seismic data by seismic companies at sea takes place by a ship periodically firing shots with an air cannon. The sound waves propagate through the water and the bedrock under the seabed. Reflection signals from horizons in the subsoil are picked up by hydrophones that are towed after the boat. The signals provide a basis for seismic maps used in geological interpretation of the exploration area.
What is seismic?
Seismic is a common term for exploration carried out to reveal geological formations below the seabed, which helps petroleum geologists gain a detailed understanding of underground structures, which can therefore help both find and uncover the size of oil and gas fields. Seismic is essential to look for oil and gas, but also important to develop new oil and gas fields and to make the most of existing fields
What do seismic companies do?
The seismic companies collect large collections of seismic data that provide information about changes in velocity and density that represent changes in the physical properties of the bedrock. Seismic data thus do not provide unambiguous information about rock type, and must therefore be interpreted geologically. The data is produced in time (seconds) according to how long it takes from the sound wave is transmitted until it returns to the surface. Time can be converted to depth (depth conversion) by knowing how fast sound propagates through the different layers.
Where are the geophysical companies located?
Many of the geophysical and seismic companies are located in the major oil and gas cities and oil capitols such as Stavanger, Norway, Aberdeen, Scotland, Houston, Texas, USA and Perth, Australia. To find “seismic companies near me” you can use the search field at the right side on this web site and enter your country or city and you will get a comprehensive list of subsea oil and gas companies near your location.
