Opening of oil and gas

Oil and gas are held in porous rocks like water in a sponge, often in pockets spread over a large area.

We use advanced technologies to look beneath land and seas for increasingly hard-to-find energy resources that can help meet the world’s growing demand.

Finding oil and gas reservoirs is a long and complex process. It can take years of research, survey work and exploration drilling before a single drop of oil or cubic meter of natural gas is produced.

We use a range of survey methods to find the best places to drill exploratory wells. These tools help us to look quickly, safely and cost-effectively for the geological formations that are most likely to contain energy resources.

Making the invisible visible

As the era of easy-to-find oil and gas comes to an end, we are developing new technologies that can detect reservoirs that were previously invisible. These reservoirs can be at depths of more than 3,000 metres, or hidden under thick layers of salt deep below the seabed, or trapped in geological faults where the rock is folded into complex structures.

High-quality images of reservoirs are essential for teams making decisions about where to explore for, or produce, oil and gas. The main challenge for the industry is how to obtain the best images in the shortest time, more cost-effectively.

To find oil and gas resources we use a range of geophysical imaging technologies. Seismic reflection imaging remains the most widely-used geophysical technique in hydrocarbon exploration.

First, we capture echoes using advanced sensors as the waves pass through, or bounce off, the rock and sediment deep underground. We place many sensors over a wide area to record waves from different angles to provide the best picture from beneath the surface in the site we are surveying.

Second, we process the vast amounts of seismic data we have gathered with high-performance computers using advanced algorithms to produce an accurate geological map of the site we are investigating.

And third, we use our GEOSIGNSTM visualisation software to turn the data into images that can be analysed and interpreted by our scientists quickly and efficiently. This ability to visualise and interpret billions of signals lies behind our biggest successes in oil and gas exploration.
