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.
