Independent Component Analysis for Filtering Airwaves in Seabed Logging Application
Marine controlled source electromagnetic (CSEM) sensing method used for the detection of hydrocarbons based reservoirs in seabed logging application does not perform well due to the presence of the airwaves (or sea-surface). These airwaves interfere with the signal that comes from the subsurface seafloor and also tend to dominate in the receiver response at larger offsets. The task is to identi...
متن کاملInterferometry in dissipative media: Addressing the shallow sea problem for Seabed Logging appli- cations
We derive interferometric field representations that are valid for diffusive field methods. The method retrieves the reflection response of the earth, as if the domain above the receiver depth level is homogeneous. It is represented as the flux-normalized up going field deconvolved by the down going field. The deconvolution step can be seen as a weighted crosscorrelation step, which is the usua...
متن کاملTransverse product effect on CSEM with double Hydrocarbon reservoir in seabed logging
In this paper, simulations are performed to reaffirm the relationship between the resistivity and the thickness of the Hydrocarbon reservoir by considering double layers of Hydrocarbon in seabed logging application. In order to establish this correlation, various simulation models are carried out using Computer Simulation Technology (CST) tool and the results obtained from each simulation is pl...
متن کاملOffshore geohazards and seabed mobility
This research stream is focussed on offshore hazards, with particular attention to the mobility of the seabed – whether through large scale geological events, or local scale sediment transport processes. This report is divided into two broad areas. We have extensive activity to report on the subject of seabed mobility, through studies around the O-Tube program (see also the separate report on t...
متن کاملTurbidity Currents and Seabed Morphology
Our main goal is to assess the hydrodynamics of turbidity currents and mudflows and their ability to produce morphological features such as ripples, dunes, antidunes and gullies along their paths. Of particular interest is to elucidate the role played by turbidity currents on the inception of submarine channels and canyons. To this end, understanding the mechanics of sediment erosion, including...
