CGG has announced that the high-powered Time-Domain Electromagnetic (TDEM) surveys conducted by its Airborne business line will now offer Induced Polarization (apparent chargeability) as an additional product.

Chargeability is an important rock property for mineral exploration and has traditionally been measured with direct current, ground-based geophysical methods which are comparatively slow and labor-intensive. Chargeability effects have been observed in TDEM data for many years and CGG has a long history of studying them and extracting the information for research and interpretation purposes.
