Latest marine geophysical technologies for comprehensive study of natural hydrocarbon reservoirs and monitoring of production

摘要

This paper presents three innovative technologies of PGS Company for marine geophysical studies: GeoStreamerGS~(TM) is for marine seismic operations, EM for resistivity surveys in combination with seismic survey on the same vessel, and OptoSeis~(TM) permanent reservoir monitoring during oil or gas production. Seismics is the major marine geophysical technique. Unfortunately, in the conventional modification its effectiveness does not exactly comply with the requirements of our time. Improvements in both the marine seismic itself, its resolution capacity and informativity, and involvement of other geophysical techniques are on the agenda today. PGS heavily invests in development of emerging technologies. The results are not late in coming. In this paper we present three innovative technologies, which our company started to offer at the geophysical services market in the last two or three years. The direct analogues that are comparable to them in terms of effectiveness and informativity are not yet present in the market.
