Filling the gap: nodes and streamer data are integrated for geophysical monitoring over a deepwater FPSO installation

摘要

In recent years, the utilization of time-lapse techniques has become an essential tool for the geophysical monitoring of producing oil and gas fields. As a result, an increasing number of seismic projects are planned and executed over obstructed areas (Figure 1). In these operational environments, health, safety and environment (HSE) rules are very restrictive. As a result, large regions remain uncovered during repeated acquisitions, and the final quality of the acquired data can severely be affected.
