TGS is preparing a multi-client onshore 3D seismic survey on the western flank of the Appalachian Basin in the US, aligning with the most prospective trend of the Utica-Point Pleasant formation and Clinton sands.
TGS is preparing a multi-client onshore 3D seismic survey on the western flank of the Appalachian Basin in the US, aligning with the most prospective trend of the Utica-Point Pleasant formation and Clinton sands.
The 206 km2 Birmingham 3D survey will target multiple exploration zones, including the Ordovician Trenton and Black River, Cambrian reservoirs, Ordovician Utica/Point Pleasant and Silurian Clinton sands. ‘This area is characterised by world-class source rocks in the Devonian Marcellus and Ordovician Utica formations,’ said TGS.
Birmingham sits just up-dip of the Point Pleasant-Utica condensate and light oil trend imaged by TGS’ Utica Merge 3D and will target the underexplored oil window of the Point Pleasant. Deep-rooted structures will be mapped, which are crucial for understanding hydrocarbon trapping, facies changes, basin heat flow and accurately landing horizontals, the company added.
TGS will leverage its data on 73,857 wells and 144,597 logs in the Ohio portion of the Appalachian Basin. Kristian Johansen, CEO of TGS, said: ‘The Birmingham 3D survey represents a significant investment towards understanding the full potential of the Appalachian Basin. Alongside our other supporting products in the region, such as our extensive well log library and interpretive products, we are confident this survey will provide valuable insights for our clients.’
The acquisition of Birmingham 3D is scheduled to commence in early Q4 2024. Preliminary products are expected to be available by Q1 2025, and final data by Q3 2025.
Meanwhile, TGS has released the Dynamic Matching FWI (DM FWI) volume for West Kermit 3D in the Delaware Basin. The final new data volumes include time reprocessing and a fully integrated depth model, featuring diving wave and reflection DM FWI.
The West Kermit 3D seismic survey spans 1054 km2 across Loving and Winkler Counties, Texas, and aids in evaluating and developing prolific multi-target Delaware Basin acreage. The FWI product enhances the structural image of the main reservoir zones, the Wolfcamp and Bone Spring intervals. TGS will provide imaging below the problematic dissolution fill zone and interpretation of the revised Rustler and Salado horizons. The enhanced image now shows visible depositional transitions from the Capitan Reef to the basin clastic deposits of the Delaware Mountain Group.
