This Vision of Onshore Seismic May Look Strange at First

This airship, called the HA2t, can lift 2 tons into remote areas, and can be shipped in a standard cargo container.

Imagine a swarm of drones hovering over a remote tropical forest dropping what looks like large darts. The darts are actually seismic receivers delivered from the air as shown in an animated video from Total. They are part of a project to rethink how surveys are done in remote spots where the jagged landscape limits movement on the ground.

The goal is to find ways to sharply reduce both the cost and the environmental impact of gathering the volumes of data needed to illuminate oil and gas deposits in complex, hard-to-image formations.

Their testing ground, Papua New Guinea, is a perfect example of the problem. Florent Bertini, Earth Imaging R&D program director at Total, describes it as “one of the most challenging places on Earth for seismic acquisition.”

And there are enough other locations where the barriers to generating the booming sounds needed for seismic and recording how it reflects off the layers below are great enough to justify taking on some extreme technical challenges.
