  • Seismic reflection, seismic crosshole and ground penetrating radar case study

    Geophysical Investigation of the Crosstown Expressway. Tampa, FL In April, 2004 Pier 97 which supported an elevated roadway in Tampa, FL was vertically displaced (collapsed) approximately 10 feet (ft). At the time of the collapse it was not known whether the collapse was associated with geological conditions at the site, specifically karst conditions, or whether is was associated with a ...

  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • Leakage from drill pipe casing subject to shear deformation

    The possibility of fluids leaking from a pressurised drill pipe casing subject to shear deformation caused by various events, including geological activity (such as seismic activity or deformations associated with subsidence related to excavation and construction) in the vicinity of the bore hole, is investigated. An experimental laboratory scoping investigation has been conducted to determine ...

  • Soil Fracturing

    Introduction Fracturing is an enhancement technology designed to increase the efficiency of other in situ technologies in difficult soil conditions. The fracturing extends and enlarges existing fissures and introduces new fractures, primarily in the horizontal direction. When fracturing has been completed, the formation is then subjected to vapor extraction, either by applying a vacuum to all ...
