        挪威地震勘探公司TGS与Schlumberger公司合作，获准对埃及红海北部地区50%以上部分进行三维勘测工作。

 

        TGS公司表示，其和Schlumberger公司对探索红海油气资源前景的初步结果感到非常满意。

 

        这项由行业资助的调查最终处理数据集预计于2022年第四季度公布。

 

        值得提醒的是，该公司2021年10月宣布的长偏移距采集项目涵盖了大约6800平方公里的区域。

 

        它采用叠前深度偏移（ Pre-Stack Depth Migration，简称PSDM）工作流程进行处理，以便在埃及石油部（the Egypt Ministry of Petroleum）和南谷埃及石油控股公司（GANOPE）所预期的一轮许可证发放之前形成盐下层成像。

 

        该地震勘探公司当时说道：“众所周知，红海拥有巨大的油气能源潜力，由于具有稳定的投资环境、完善的勘探基础设施以及定期、透明和管理良好的许可发放轮次，在埃及进行勘探的机遇因而得以加强。”

 

        与此同时，TGS公司和Schlumberger公司的地球物理服务产品线“WesternGeco”近期在美国墨西哥湾格林峡谷（Green Canyon）开始了超长偏移洋底结点（ocean-bottom node，简称OBN）采集工作的第二阶段。 

 

        对168个OCS区块的调查工作开始于2021年8月，预计在2022年第一季度完成。这次数据处理将于2022年年中产生结果。

TGS more than halfway through Egyptian Red Sea 3D survey

 

Norwegian seismic player TGS, in partnership with Schlumberger, has acquired over 50% of the 3D survey over the northern portion of the Egyptian Red Sea.

 

TGS said that the company and Schlumberger are very pleased with the preliminary results of the survey exploring Red Sea hydrocarbon prospectivity.

 

The final processed dataset from this industry-funded survey is expected in the fourth quarter of 2022.

 

To remind, the long offset acquisition, announced in October 2021, covers an area of approximately 6,800 square kilometres.

 

It is processed using a Pre-Stack Depth Migration (PSDM) workflow to enable subsalt imaging ahead of the anticipated license round from the Egypt Ministry of Petroleum and South Valley Egyptian Petroleum holding company (GANOPE).

 

“The Red Sea is considered to hold significant hydrocarbon potential, and opportunities in Egypt are enhanced by a stable investment environment, established exploration infrastructure and regular, transparent, and well-managed licensing rounds”, the seismic company said at the time.

 

Meanwhile, TGS and WesternGeco, the geophysical services product line of Schlumberger, recently started the Engagement Phase 2 of their ultra-long offset ocean-bottom node (OBN) acquisition in Green Canyon, U.S. Gulf of Mexico. 

 

The 168 OCS block survey began in August 2021 and is expected to be completed during the first quarter of 2022. The results from this data processing are expected in mid-2022.
