South Makassar Basin - Indonesia - 2018

South Makassar 3D GeoStreamer® (In Processing)

Reveals potential plays in the South Makassar Basin to enable prospect delineation and development
Website Map for Survey South Makassar
This MultiClient survey will bring new insight to help assess target reservoirs and play types present in nearby fields.
In particular, the distribution of the early syn-rift (a potential source rock), and the basement definition are expected to be much improved.
GeoStreamer data will improve resolution of seismic events and imaging of structure, and better depth penetration will highlight deeper plays in the basin. The combination of hydrophone and velocity sensor recordings allows precise receiver deghosting via a method of wavefield separation.
