Successful decommissioning of subsea oil and gas infrastructure requires a safe effective approach to assess manage waste products. These products, often present as scale on internals pipelines, include naturally occurring radioactive materials (NORM) trace metals. Understanding the potential effects these contaminants marine fauna is crucial managing global decommissioning. This review compose...

This paper discusses a GIS based decision support system that supports the petroleum upstream investment decision-making. Functions of prospect screening and evaluation in both technical aspects (Volume, structure, trap, reservoir and charge, etc.) and economic aspects (Net present value, Investment / profit Ratio, etc.) are designed and integrated into a GIS platform to supports and facilitate...

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. S...

Loss of containment in the oil and gas and chemical process industries can have undesirable safety and environmental consequences. If leaks are not discovered at an early stage, they can accumulate into dangerous gas clouds that can ignite and create explosions or inflict harm as toxic agents. A recent report by British Petroleum estimates a single cavity pressure vent at an unmanned offshore p...

In ratifJingthe United Nations Convention on the Law of the Sea in 1994, Australia took responsibility tor a marine jurisdiction that is more than 1.5 times the area of the landmass. While ownership of offshore resources provided under UNCLOS hestows certain rights (including exploitation), it also carries a range of obligations, including the protection and preservation of the marine environme...

In this paper we propose an integrated approach to diagnostic prospecting applied to the cathedral of Matera, in Southern Italy. In particular, we have performed both an ultrasonic tomography and a high frequency GPR prospecting on some pillars of the Church to investigate about possible structural yielding and a GPR prospecting at lower frequencies on the floor, where also a linear inversion a...
