Offshore Hydrocarbon Seepage Characterization through Spectroscopy, Multivariate Statistics and Optical Remote Sensing
نویسندگان
چکیده
Remote sensing has been a key tool for ocean slicks monitoring and new discoveries based on offshore seepage detection. In this context, this contribution has a two-fold objective. Firstly, in order to spectrally characterize hydrocarbons (HCs), we conducted VNIR-SWIR-TIR spectral measurements of petroleum samples yielded from large, off-shore oil fields sited at sedimentary basins of Brazil. Secondly, we employed these spectral signatures in an attempt to map and characterize a substantial HC seepage verified at the Campos basin (Rio de Janeiro coast – Brazil) using ASTER multispectral imagery.

Oil and gas reservoir has long-term suffering from hydrocarbon seepages including macroseepages and microseepages. The presence of seepages documents the first element of a hydrocarbon system and could therefore reduce exploration risks. Hydrocarbons that escape from underground reservoirs cause oxidation-reduction reactions either in situ or along vertical migration pathways and result in anom...

Prolific natural hydrocarbon seepage occurs offshore of Coal Oil Point in the Santa Barbara Channel, California. Within the water column above submarine vents, plumes of hydrocarbon gas bubbles act as acoustic scattering targets. Using 3.5 kHz sonar data, seep distribution offshore of Coal Oil Point was mapped for August 1996, July 1995, and July 1973. Comparison of the seep distributions over ...
