Abstract

Summary

Exploration 3D seismic surveys are generally acquired to image potential reservoirs at minimum cost and may be poorly suited to imaging of the near surface. Modern processing techniques can overcome some of these limitations and enable the generation, from exploration surveys, of 3D seismic cubes for identification of shallow hazards. These can provide temporal resolution close to conventional site survey seismic data, whilst covering a larger area with greater spatial resolution. Generating these cubes in parallel with deep seismic processing ensures that they are consistent and available at the same time as the exploration 3D seismic data. An integrated team of specialists can work together during exploration to identify appropriate surface well locations concurrently with definition of subsurface drilling targets, which contrasts with the more conventional sequential approach where site surveys are acquired and analyzed after target identification. The new approach has the potential to provide greater operational efficiency and reduced time to first oil
