TGS, a global leader in energy data and intelligence, in collaboration with joint venture partner Viridien, an advanced technology, digital and earth data company, today announced the availability of early out results from the Laconia Phase III ultra-long offset ocean bottom node (OBN) survey in the Gulf of America.

The initial 5Hz Acoustic TLFWI (AFWI) Ocean Bottom Node (OBN) products from the Laconia Phase III survey are now available, covering the full 151 Outer Continental Shelf (OCS) block area. These early results demonstrate significant imaging uplift and provide valuable insight to help reduce exploration risk across key Paleogene targets ahead of US lease sale BBG 1 (lease sale 262) this Dec. 10, 2025.

Building on these results, the project will deliver Fast Track 5Hz Elastic TLFWI (EFWI) products in Q1 2026 followed by final 12Hz EFWI volumes in January 2027. The enhanced resolution and imaging improvements from the EFWI processing will further support exploration of the Paleogene.

"The successful and safe towing of the dual TPS low frequency source for Laconia Phase III reflects the exceptional capabilities of TGS' OBN operations team," said David Hajovsky, EVP, Multi-Client, TGS. "Their precision, adaptability, and commitment to excellence have enabled us to deliver industry-leading data quality in one of the more technically demanding plays in the Gulf of America. This achievement is a cornerstone of the imaging uplift we are seeing and a clear demonstration of TGS’ operational strength.”

Dechun Lin, EVP, Earth Data, Viridien, said: “The early results from Laconia Phase III demonstrate the impact of our advanced imaging technologies in unlocking the potential of the Paleogene play in deep water Gulf of America.”
