WesternGeco experts and innovative technology help explorers reduce survey costs, save time and improve data quality. These benefits build upon the fundamentally better measurements provided by our Q-Technology point-receiver seismic hardware and software.
On land, our UniQ integrated point-receiver land seismic system, with its superior noise suppression capabilities, allows for efficient acquisition with a more flexible sensor-density arrangement, which can result in a 100 % boost to crew productivity. In an exploration environment, superior data can be acquired with far fewer sensors than conventional methods; test results have shown that just 4–8 sensors per 50 m can deliver equivalent ambient noise suppression to standard geophone arrays of 12–48 sensors.
A recent study for an exploration project proposal in North Africa showed UniQ technology was capable of delivering fit-for-purpose exploration data in less than half the time it takes a traditional slip sweep operation.
Offshore, enabled by the DSC dynamic spread control technique and the Q-Marine single-sensor marine seismic system, CLA - Continuous Line Acquisition significantly increases seismic vessel efficiency. Traditional seismic surveys acquire data along straight lines and then suspend acquisition as the vessel turns around and runs into the next line. By shortening the lines and acquiring data during the turns, it is possible to optimize vessel use, increasing efficiency by up to 100 %, when compared to conventional methods.

In areas with limited well data, controlled-source electromagnetic (CSEM) inversion technology integrated with structural models can help to identify and rank prospects. A recent CSEM inversion constrained by seismic interpretations offshore West Greenland clearly delineated resistive bodies on 8 of the 14 prospects surveyed, demonstrating considerable confidence in the ‘high-grading’ of the prospect portfolio for drilling locations.
