Main Problem of SR/GPR acquisition:Main Problem of SR/GPR acquisition:

Real-time processing is difficult and cost intensive

Acquisition parameters such as recording time, sampling interval, source strength and receiver

spacing cannot be optimized in the field

Solution: Wireless data

transmission + remote GRID computing facilities

Remote Grid Computing

Preprocessing and Visualization using SU:

Basic preprocessing steps can be applied without installing the complex SU processing package.

Data-driven CRS imaging technology---state-of-the-art in oil exploration---enables highly automated data processing.

Imaging and RSC using CRS technology:

GRID deployment using high performance computing facilities provides the necessary computing power.

Parallel processing of different workflows: Cumbersome sequential optimization of processing

workflow and processing parameters speeds up drastically.
