Seismic survey points

Improve Seismic Survey Planning with Highly Accurate Elevation Models

When planning a seismic survey, petroleum engineers need to know which seismic source points can be accessed safely by vibroseis trucks. Using high detail elevation models generated from satellite imagery, PhotoSat can help.

We use elevation surveying to prepare the groundwork for seismic surveying. Before holes are drilled or vibroseis trucks are on the move, planners know where the likely best spots are. And thanks to PhotoSat’s 30cm accuracy elevation models, they also know where trucks can’t go.

Overturning vibroseis trucks on steep or sudden inclines is a real risk. Planners need more than contour lines: they need high resolution, accurate topographical data to allow them to plan how to best use their vibroseis equipment while keeping their trucks and crews safe. Mapping the ground slope to within 30cm elevation accuracy enables mapping of no-go zones that are too steep for vibrator truck operations, lowering the risk of overturning the vibes on steep inclines. Our clients tell us that this improvement in seismic survey planning helps them reduce project costs and saves time.

Advance scouting is expensive, risky and time-consuming. And it comes under fire for its environmental impact. PhotoSat’s proprietary geophysical processing system allows us to create usable digital elevation models and precision satellite images within just a few days of a satellite acquisition, with 30cm elevation accuracy and with no boots – or tires – on the ground. The resultant data can then be used for subsequent project engineering and design.

Another advantage of having accurate survey data in the early project stages is the ability to use the elevation models for quality control of the seismic shot and receiver point survey data. In addition, the data is engineering-quality and can be used for all future design and construction work. This reduces survey wait times and allows managers to have increased faith in the reliability of the data.

So how do we get these kinds of accuracies? We have developed our own unique process, and more information can be found on the Technology page. Also, we have published numerous Proof of Accuracy Reports, that compare our elevation data to tens of thousands of independent survey points.
