Seismic migration

Imagine you are playing a game of hide and seek, but instead of looking for a person, you are searching for oil or gas hidden deep under the ground. You cannot see below the surface, so you have to use sound waves to create a picture of what’s under the ground. This is called seismic imaging.

Seismic imaging works by sending sound waves into the ground and listening to how they bounce back. It’s like clapping your hands in a room and hearing the echo. The sound waves bounce off different layers of rock and other features under the ground and come back to the surface. Special sensors called geophones detect these sound waves and record them as data.

Now, imagine you are trying to create a map of what’s under the ground, but the sound waves are bouncing the wrong way, making it difficult to get a clear picture. This is where seismic migration comes in.

Seismic migration is like cleaning up a messy picture. You take the data recorded by the geophones and use computers to improve the images. It’s like an artist who sketches a rough outline and then fills in the details to create a clearer picture.

Seismic migration uses complex algorithms to clean up the data and make it easier to understand. It helps geologists and engineers locate oil or gas deposits hidden deep under the ground more accurately. By improving the quality of the images, seismic migration can save time and money during the process of exploring for fossil fuels.
