To optimize seismic data for advanced pre-stack time migration (PreSTM) and Pre-stack depth migration (PreSDM), data conditioning is required to enhance raw data signal-to-noise. Relative amplitude processing, rigorous noise analysis (and its removal with appropriate tools), and stringent quality control using proprietary techniques are all critical elements to accomplish this goal.
Vast Experience in Data Conditioning
ION excels at conditioning land-acquired data during pre-processing. Our techniques correct for topography, account for differences in elevations among sources and receivers, and model near-surface velocity anomalies caused by the weathering layer, Arctic permafrost, ice lakes, desert hard pan, and sand dunes.
