Energy data company TGS has acquired Swissbased Apparition Geoservices to strengthen its seismic survey capabilities and improve subsurface imaging for energy exploration projects. The acquisition gives TGS exclusive access to Apparition’s simultaneous source acquisition and separation technology. TGS plans to combine the technology with its Gemini Enhanced Frequency Source (EFS) system to boost operational ef?ciency, increase source capacity and deliver clearer subsurface images for clients. According to the company, tests conducted over the past two years showed ef?ciency gains of up to 30%, alongside improved signal quality, stronger low-frequency performance and better visibility of deeper and more complex geological targets. The technology will be integrated into TGS’s ocean-bottom node (OBN), towed streamer and ultrahigh-resolution 3D survey operations using its Ramform vessel ?eet.
