Skills & Interests: 

My research is interdisciplinary, spanning the fields of seismic analysis, theory and modeling. Recently I have primarily focused on the study of:

• Theoretical model to describe velocity versus gas hydrate and free gas concentrations and velocity versus pore pressure;

• Theoretical amplitude versus offset (AVO) curves to describe the effect of hydrate and free gas presence, overpressure condition and fluid presence in general;

• Seismic modeling to describe the seismic effect of hydrate and free gas presence and overpressure condition;

• Simulation of torsional, extensional and coupled waves in a borehole in order to better interpret well data;

• Advanced processing, such as datuming wave equation (WED) applied to crustal, high resolution land seismic, and Ocean Bottom Seismometer data;

• Algorithms and related codes to perform AVO and CIG (software named ISTRICI) analyses and to estimate the gas hydrate and free gas concentrations and the pore pressure regime (software named DRAGO);

• Integration analysis between different geophysical dataset.

The above studies are applied for different targets: characterization the gas hydrate reservoir, effect of climate change, and pressure/temperature change in general, on gas hydrate stability, characterization of aquifers, and analysis of crustal seismic data. The above mentioned analyses are also applied in environmental projects related to seismic risk. The developed procedures to analyze the seismic data have been the object of several invited talks and lessons. Moreover, the codes are disseminated in different contest in order to promote the collaboration with several countries (China, India, Norway, and Spain).

Major projects: 

Recently funded research projects relevant to gas hydrate studies (P.I. U. Tinivella):
