Viridien, an advanced technology, digital and Earth data company, in collaboration with TGS, a global leader in energy data and intelligence, has announced the completion of the acquisition of the Laconia Phase III ultra-long offset ocean bottom node (OBN) survey in the Gulf of America. This latest phase spans 151 OCS blocks and expands ultra-long offset low-frequency OBN coverage of the Paleogene trend to provide improved seismic data and subsurface imaging over this geologically complex area. The survey was acquired by a TGS deepwater OBN crew using TGS’ ZXPLR™ nodes and Sercel’s Tuned Pulse Source (TPS™). The Laconia Phase III data set will be imaged using Viridien’s industry-leading elastic full-waveform inversion (E-FWI) to improve subsalt structural clarity and support further exploration in central Keathley Canyon. Phase III of the Laconia program represents an important step forward for exploration in Keathley Canyon.”David Hajovsky, EVP Multi-Client at TGS, commented: “Laconia Phase III is designed to significantly enhance imaging, optimizing near-term exploration of the critical Paleogene play.
