Seismic Data Acquisition

PG-SERV services the resources sector by conducting 2D & 3D seismic surveys to image geology from near surface shallow coal seams (30m - 1km) to deep crustal basement (50km) and everything in between. 

2D Onshore Acquisition

• Provides a cross section of the subsurface in two planes, horizontally and vertically.
• Acquired with single or multiple sources and a single line of receivers. Each line is processed individually and independently.
• Lines are often set far apart so they only provide a snapshot of the subsurface.
• The 2D data is typically used for mapping multiple basins and deposition trends across a large region.

3D Onshore Acquisition

• Receivers are spaced closer together to produce a more accurate three dimensional picture of the subsurface.
• The 3D data is good for focusing on multiple targets, pinpointing more exact prospects and subsurface drilling hazards.
• The data is then subjected to complex mathematical algorithms that eventually produce an image of the subsurface.

Once seismic data has been processed, it is given to interpreters for analysis. To make an informed decision on whether a well will be productive, interpreters consider the geological features, the geophysical data and any other test or survey results available on the prospect area.

Main goal is to determine if geological situations exist in the subsurface where hydrocarbons may be found. This step puts all the components together to determine if the prospect area is a good economic risk.
