Norwegian seismic services provider Petroleum Geo-Services (PGS) has reached an agreement with Perupetro to create a new MegaSurvey in Peru.

PGS said last week that the first data from the MegaSurvey would be available in the first quarter of 2020.

The company added that this large-scale merged and matched dataset would provide an excellent opportunity to evaluate prospectivity on a regional basis.

The PGS Peru MegaSurvey comprises 21,000 square kilometers of 3D seismic. This data will be matched and merged, together with approximately 23,000 kilometers of 2D data.

The resultant dataset will be converted into depth from a seismic-horizon-constrained velocity model that extends through five different basins, from the prolific Talara basin in the north to the frontier basins in the extreme south.

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.

The PGS Peru MegaSurvey covers both existing discoveries and licensing opportunities in open blocks. It can be used to pick prospects or to evaluate the successes and failures across the entire region.
