Schönkirchen 3D Seismic Survey
This was a major onshore 3D seismic survey in the Vienna Basin for OMV Austria. The aim of the seismic survey was to acquire deep geological data under a mature producing oilfield. There were significant environmental and time constraints on the project which were successfully overcome.

Challenge
This was a detailed 3D study covering a variety of environmentally sensitive areas. There were many roads and villages, an operating oil field and large expanses of farmland, including commercial vineyards.
To avoid causing damage to crops, the survey was planned for the winter months and had to be completed before farmers commenced work again in the spring.
Technically the geologic target was deep, and the aim was to acquire a high-quality full azimuth dataset at a reasonable cost.
Solution
The programme used innovative techniques to acquire the seismic data. These included the use of a cable-free nodal recording system to minimise the physical impact of the survey, and four fleets of seismic vibrators operating in “slip sweep” mode to maximise production.
