Quick Facts on Seismic Technology in Oil and Gas
- Seismic surveys are conducted using sound waves that are bounced off underground rock structures, which are then recorded by geophones on the surface.
- Advancements in seismic technology have led to the development of 3D seismic imaging, which provides a more detailed and accurate picture of the subsurface than traditional 2D seismic imaging.
- 4D seismic technology, or time-lapse seismic monitoring, is a newer advancement that allows for the monitoring of changes in a reservoir over time.
- Seismic technology advancements have also led to the development of multi-component seismic, which records both compressional waves and shear waves to provide a more complete picture of the subsurface.
- Ocean-bottom seismic (OBS) technology is another advancement that allows for the collection of high-quality seismic data in offshore environments.
- Seismic technology can now be used in combination with other technologies, such as electromagnetic imaging, to improve the accuracy of oil and gas exploration.
A report by Mordor Intelligence highlights how the seismic survey market, a significant part of this seismic technology landscape, is expected to grow at a CAGR of approximately 4.5%, during the forecast period of 2021-2026. This growth is envisioned to be driven by the continuous quest for new oil and gas fields, technologically-driven production increase, and the dire need for recovery efficiency improvement.
“In the quest for more comprehensive and accurate exploratory data, seismic technology serves as a crucial tool for petroleum engineers and geological surveyors. It offers a lens into the underground that no traditional prospecting method can match,” says Dr. Sarah Hardy, a veteran petroleum engineer.
From 3D seismic imaging that offers a detailed snapshot of the underground landscape to the advanced seismic monitoring techniques capable of tracking the continuous changes in reservoirs, the latest advancements in seismic technology are essentially revolutionizing the oil and gas industry.
