CGG introduces induced polarization from airborne electromagnetic data
PARIS, France -- 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.
CGG is now commercializing an airborne TDEM chargeability product as part of its suite of TDEM deliverables for mineral exploration solutions. Explorers will be able to take advantage of the high speed and full coverage of airborne surveys to measure both inductive resistivity and chargeability to rapidly discriminate ore bodies. This new product deliverable also extends to legacy data.
Chargeability can be a significant targeting tool in mineral exploration as a useful discriminator for metallic deposit characteristics.
Benoît Ribadeau Dumas, executive V.P., Acquisition, CGG, said: “Commercialization of this product is based on Airborne’s technical leadership and long experience in the field of EM and is a significant benefit to explorationists in their quest to discover, discriminate, and appraise metallic ore deposits. It complements our recent launch of our new MULTIPULSE EM service and we foresee a significant uptake in this added value service offered by our Airborne Business Line.”
