TGS Announces Birmingham-Gemini 3D Seismic Survey in Appalachian Basin

TGS Announces Birmingham-Gemini 3D Seismic Survey in Appalachian Basin

OSLO, Norway (23 October 2024) - TGS, a global leader in energy data and

intelligence, today announced an extension to the Birmingham 3D seismic survey

covering 276 square miles. The survey is strategically located on the western

flank of the Appalachian Basin, aligning with the most prospective trend of the

Utica-Point Pleasant formation and Clinton sands.

Kristian Johansen, CEO of TGS, commented: "The Birmingham-Gemini 3D survey

reflects TGS' commitment to uncovering the Appalachian Basin's potential.

Combined with our well-log database and analytical products, it provides clients

with critical insights to drive exploration and production success, highlighting

our dedication to delivering premium geoscience data for informed decision-

making."

The Birmingham-Gemini 3D seismic survey will target key formations in the

Appalachian Basin, including the Ordovician Trenton, Black River, Utica/Point

Pleasant, Cambrian reservoirs, and Silurian Clinton sands. Positioned up-dip

from the Utica condensate and gas trend, the survey aims to explore the under-

explored Point Pleasant oil window.

Using advanced seismic imaging, the project will map deep structures to identify

hydrocarbon traps, analyze facies changes and optimize well placement. These

insights will aid operators in refining exploration and production strategies.

TGS will enhance the seismic data by integrating it with its extensive

Appalachian geologic and well database, including over 480,000 well logs.

Proprietary formation tops and well performance metrics, available through the

TGS Well Data Analytics platform (https://www.tgs.com/well-data-products/well-

data-analytics), provide clients with comprehensive analysis for deeper insights

into the region's potential.

Recording for the Birmingham-Gemini 3D survey will commence in early 2025, with

the fully processed dataset available to clients by year-end.

This project is supported by industry funding.
