Abstract

Quality in all the E&P activities of ONGC is re-emphasized and continuous improvement in terms of quality of all the activities has become the order of the day. In this direction to have real time quality checks of seismic data at the acquisition stage itself, Field processing units (FPU) were introduced, by the Geophysical Services of ONGC. This has improved the quality of seismic data acquired and reduced the time delay in getting the feedback on the quality of data acquired. The incompatibility of cartridge drives used in the FPU and SN388 data acquisition system was delaying the real time QC in the field itself. At Geophysical Services, Jorhat this issue was addressed and an optimum solution in terms of time & cost was arrived at. The different options explored and an acceptable solution arrived at are discussed in this paper.
