Single-Sensor Recording - A Case Study from the Partitioned Neutral Zone

摘要

This paper shows how changing the paradigms used for 3D seismic acquisition and processing can extend the usefulness of 3D surface seismic methods. To demonstrate this, a case study from the Partitioned Neutral Zone between the Kingdom of Saudi Arabia and Kuwait, which is jointly operated by the Kuwait Oil Company (KOC) and Saudi Arabian Texaco (SAT), known collectively as the Joint Operating Company (JOC), will be used. As demands for the information provided by seismic data have increased from delivering a structural picture to generating reservoir information in the inter-well space, conventional 3D seismic survey fold has increased to very high levels in an attempt to attenuate residual coherent noise while trying to deliver the high-fidelity seismic datasets required for such analysis, all of which comes with additional cost and uncertainty. In the Middle East, where strong coherent surface-generated noise is prevalent, a plateau has been reached regarding how much information conventional seismic data recorded with surface arrays can provide. This paper show that single-sensor recording allows the recording of higher-fidelity seismic data with both a broader bandwidth and lower noise floor, extending the usefulness of the surface seismic data.
