Make the most of your nodal data at the outset
Bringing to the table uncommon nodal expertise, Fairfield Geotechnologies has developed a range of proprietary processing techniques to address the unique challenges of this highly specialized technology. Getting the most of the dense, high-quality seismic data acquired means building a solid foundation at the earliest stages of node processing.
We deliver—with a series of 4D-compliant procedures, workflows and proprietary technologies that include:
- Data validation – raw OBN field data is carefully inventoried, and quality-checked
- Orientation, tilt, and vector-fidelity analysis
- Direct-wave traveltime analysis – the heart of the front-end sequence where we correct for clock drift, shot and receiver position uncertainty, and dynamic water-layer acoustic characteristics
- Simultaneous source de-blending – efficient node acquisition often utilizes two independent, simultaneous sources; these “blended” shots recorded by each node must be separated or de-blended
