Subsidence problems due to underground fluid withdrawal have been long recorded all over the world, causing heavy effect on the environment. In Italy, numerous cases have been recognized, in the areas of Po Delta and the cities of Venice, Ravenna and Bologna. Many studies are under development to further investigate the influence of gas production on subsidence, coastal regression and upsetting of the hydraulic system. Attention is paid to the studies on the application of new tools and modeling techniques to measure and predict reservoir compaction. The purpose of this research is at first to report the very well known subsidence case histories of the towns of Ravenna and Bologna. Finally, the research discusses the measurement of mechanical properties of Northern Italy clastic formations. In particular the research reports both the laboratory measurements and the in-situ investigations of formation compaction by means of extensometers and radioactive markers. In addition, it has also been attempted an approach to estimate the precision and accuracy of the above techniques, and the perturbation effects induced by in-situ monitoring systems.

Abstract
Subsidence problems due to underground fluid withdrawal have been long recorded all over the world, causing heavy effect on the environment. In Italy, numerous cases have been recognized, in the areas of Po Delta and the cities of Venice, Ravenna and Bologna. Many studies are under development to further investigate the influence of gas production on subsidence, coastal regression and upsetting of the hydraulic system. Attention is paid to the studies on the application of new tools and modeling techniques to measure and predict reservoir compaction. The purpose of this research is at first to report the very well known subsidence case histories of the towns of Ravenna and Bologna. Finally, the research discusses the measurement of mechanical properties of Northern Italy clastic formations. In particular the research reports both the laboratory measurements and the in-situ investigations of formation compaction by means of extensometers and radioactive markers. In addition, it has also been attempted an approach to estimate the precision and accuracy of the above techniques, and the perturbation effects induced by in-situ monitoring systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
