The leakage of petroleum can lead to serious economical loss. How to find out leakage spot is the key technology that we will discuss in the paper. In this paper, we apply wavelet transform to solving the problem. Because the audio signal from the leakage spot is very weak, when the sound spreads to the ends, the signal tested by sensor has been sinked down by other noise signals. It is difficu...

Studies were carried out on the localization and mapping of gas stations in the urban area of São Carlos city, for an environmental diagnosis related to soil, surface water and underground water contamination resulting from likely leaking in fuel underground storage tanks. Considering that a provision of legal restriction makes it possible that most of public areas are not located in gas statio...

The geological sequestration of carbon dioxide (CO2) is a well-known source of permanent changes to the fluid chemistry and to the physical properties of the host rocks. The coupling between hydrologic, chemical and deformation processes related with CO2 injection is indeed a major cause of distributed damage, and hence of potential leakage of the injected fluid. Since the success of this techn...

Climate change research with the economic methodology of cost–benefit analysis is challenging because of valuation and ethical issues associated with the long delays between CO2 emissions and much of their potential damages, typically of several centuries. The large uncertainties with which climate change impacts are known today and the possibly temporary nature of some envisaged CO2 abatement ...

The Industrial Revolution has led to a substantial i ncrease in the generation and release of greenhouse gases (GHG) into environment. These GHGs like CO2 if present in abundance in the atmosphere cause damage to the natural ecosystems through global warming. One of the possible approaches to mitigate the global warming phenomena is by safely and long-term underground disposal of CO2 in suitabl...
