该公司 6 月 20 日表示，总部位于挪威的 TGS 已完成对美国湾密西西比峡谷和尤因滩地区等近 50 个外大陆架 (OCS) 区块的调查。

修订阶段 4 超长偏移海底节点 (OBN) 调查旨在通过高保真地震数据为准备即将到来的海上租赁轮次的公司提供见解。

TGS表示，此次勘探标志着其Gemini增强频率地震震源首次在墨西哥湾的超长偏移距采集环境中部署。TGS在一份新闻稿中表示，该技术“能够发出独特的低频全向信号，结合先进的处理技术，显著改善复杂盐体下方的照明效果”。

Norway-based TGS has completed a survey covering nearly 50 Outer Continental Shelf (OCS) blocks, including in the Mississippi Canyon and Ewing Bank areas, in the Gulf of America, the company said June 20.

The Amendment Phase 4 ultra-long offset ocean bottom node (OBN) survey is intended to provide insight via high-fidelity seismic data for companies preparing for upcoming offshore leasing rounds.

TGS said the survey marked the first deployment of its Gemini enhanced-frequency seismic source in an ultra-long offset acquisition setting in the Gulf. The technology “delivers a unique low-frequency, omnidirectional signal that, combined with advanced processing techniques, significantly improves illumination beneath complex salt bodies,” TGS said in a news release.
