挪威石油地质测量服务公司(PGS)与秘鲁国家石油公司(Perupetro)签署了一项协议,将在秘鲁新建一个数据库 MegaSurvey。
这一针对秘鲁广阔海岸线数据的大规模合并和匹配数据库,将为勘探区域前景进行评估提供数据支持的机会。
秘鲁国家石油的数据库MegaSurvey 包含21000平方公里的三维地震数据,这些数据将与大约23000平方公里的二维数据合并和匹配。
挪威石油地质服务公司表示,三维和二维数据库的结果将从地震水平约束速度模型转换成深度,该模型延伸到五个不同的盆地。
这些盆地包括北部多产的塔拉拉盆地和最南端的边界盆地。
挪威石油地质服务公司在一份声明中说:“MegaSurveys是非常大的、合并的叠后数据库,由多个调查组成,这些调查被重新合并到一个共同的网格中,然后进行匹配,以产生一个相位平衡的、均匀缩放的连续区域体积。
“这种广泛的覆盖面可以用来确定新的潜在地区或在已探明的领域继续探索,揭示现有利益的类似油田。野外地质认识现在可以放在整个盆地范围内。”
该调查的区域性质允许对构造和盆地发展进行更充分的勘探。这将有助于更好地了解现有和潜在的石油体系。
挪威石油地质服务公司在秘鲁新建的数据库MegaSurvey涵盖了现有的发现和开放区块部分数据,可以用来选择分析整个地区的勘探前景。
它还可以用来评估该地区以前遇到的成功和失败。
挪威石油地质服务公司表示,该公司与秘鲁石油合作新建的数据库MegaSurvey第一款合并产品预计将于明年第一季度上市。

PGS partners with Perupetro on Peru MegaSurvey
Norwegian survey services firm Petroleum Geo-Services (PGS) has signed an agreement with Perupetro to create a new MegaSurvey in Peru.
This large-scale merged and matched dataset targeting the extensive coastline of Peru will provide an opportunity for evaluation based on the regional prospects.
The PGS Peru MegaSurvey consists of 21,000km2 of 3D seismic data, which will be merged and matched together with around 23,000km2 of 2D data.
PGS said that the results of 3D and 2D dataset will be converted into depth from a seismic-horizon-constrained velocity model, which extends through five different basins.
These basins include the prolific Talara basin in the north to the frontier basins in the extreme south.
PGS said in a statement: “MegaSurveys are very large, merged, post-stack datasets consisting of multiple surveys that have been rebinned to a common grid and then matched to produce a phase-balanced and uniformly scaled contiguous regional volume.
“This extensive coverage can be used to identify new prospects or to continue exploration in proven areas, revealing analogues of existing interests. Field-scale geological understanding can now be placed in a basin-wide context.”
The regional nature of the survey permits fuller exploration of tectonic and basin developments. This will give a better understanding of existing and potential petroleum systems.
Covering both existing discoveries and licensing opportunities in open blocks, the PGS Peru MegaSurvey can be used to select prospects across the entire region.
It can also be used to evaluate the successes and failures previously encountered across the region.
According to the company, a first merged product from the PGS Peru MegaSurvey is expected to be available from the first quarter of next year.
