CGG、Searcher 启动卡那封盆地地震项目

2017 年 1 月 19 日

澳大利亚珀斯——Searcher Seismic 与项目合作伙伴 CGG 合作,已开始对西澳大利亚卡那封盆地约 1,668 km 2的 3D 地震数据进行 PSDM 后处理。

该项目包括对 Searcher 和 CGG 收购的现有 Foxhound 3D 地震勘测西部部分进行宽带 PSDM 后处理,并覆盖 2016 年澳大利亚面积发布。

该勘测分为两部分:西部立方体位于东北部,靠近 Chandon、Martell 和 Io/Jansz 油田;东部部分位于东北偏北,靠近 Pluto 和 Wheatstone 油田。

Searcher Seismic 地球科学经理约书亚·索普 (Joshua Thorp) 表示:“Foxhound 3D 勘测最初于 2009 年进行,面临着来自崎岖海底、高度河道化的第三纪剖面和深三叠纪珊瑚礁的许多具有挑战性的地球物理问题。” “改善相位控制,特别是在低端,并使用综合地球科学方法创建高分辨率速度模型将增强侏罗纪和三叠纪区域的成像。”

“从附近的 Drop Bear Ultracube 数据中我们可以看出,这将使勘探团队能够超越 AVO 分析,并在这个高产盆地实施尖端的 QI 技术,”索普补充道。

最终 PSDM 数据将于 2017 年第三季度提供。

CGG, Searcher commence Carnarvon basin seismic project

January 19, 2017

PERTH, Australia -- Searcher Seismic, in conjunction with project partner CGG, has commenced the PSDM reprocessing of ~1,668 km2 of 3D seismic data in the Carnarvon basin, Western Australia.

The project comprises broadband PSDM reprocessing of the Western portion of the existing Foxhound 3D Seismic Survey, acquired by Searcher and CGG, and includes coverage to the 2016 Australian Acreage Release.

The survey is split into two portions—the Western cube, which lies northeast and on trend to Chandon, Martell and Io/Jansz fields, and the Eastern portion, which lies north-northeast and on trend to Pluto and Wheatstone fields.

“Originally acquired in 2009, the Foxhound 3D survey faced many challenging geophysical issues from a rugose seabed, a highly channelized Tertiary section and deep Triassic reefs,” Joshua Thorp, geoscience manager, Searcher Seismic, said. “Improving the phase control, particularly at the low end, and using an integrated geoscience approach to create a high resolution velocity model will enhance the imaging in the Jurassic and Triassic plays.”

“As we’ve seen from our nearby Drop Bear Ultracube data, this will allow exploration teams to move beyond AVO analysis and implement cutting edge QI techniques in this highly prolific basin,” Thorp added.

Final PSDM data will be available in third-quarter 2017.
