TGS has extended the Birmingham 3D seismic survey in the Appalachian Basin, the energy data provider said in an Oct. 23 press release.

The survey, which is positioned up-dip from the Utica condensate and gas trend, will target 276 sq miles of formations, including the Ordovician Trenton, Black River, Utica/Point Pleasant, Cambrian reservoirs and Silurian Clinton sands, TGS said.

The 3D survey uses seismic imaging to map deep structures to aid E&Ps in identifying hydrocarbon traps, analyzing facies changes and optimizing well placement.

“Combined with our well-log database and analytical products, it [Birmingham-Gemini 3D survey] provides clients with critical insights to drive exploration and production success, highlighting our dedication to delivering premium geoscience data for informed decision-making,” said Kristian Johansen, CEO of TGS.

Recording for the Birmingham-Gemini 3D survey will commence in early 2025, with the fully processed dataset available to clients by year-end.

S&P Global assigned TGS a ‘BB-‘ rating on Oct. 23. This follows Moody’s Ratings upgrade for TGS to Ba3 from Ba2 on Sept. 26.
