In our lab., we have been conducting research based on geomechanics for various applications such as CO2 geological storage, methane hydrate from deep seafloor, unconventional resources (shale gas &amp; oil), easy and reliable in-situ stress measurement, and supercritical geothermal resource development. We develop the technology to highly utilize the subsurface environment (temperature, stress, closedness) to solve many challenges related to energy and to realize a sustainable society. We are trying to comprehensively understand various failure phenomena related to subsurface development by the broad approach of a laboratory experiment, numerical simulation, and field data analysis.<\/div>\r\n<\/div>\r\n<div class=\"contents\">\r\n<div class=\"wrapper\">\r\n<h4>Study of Hydraulic Fracturing in Unconsolidated Formation for Oil and Methane Hydrate Development<\/h4>\r\n<div>The technique of hydraulic fracturing has been originally developed, assuming cohesive rocks. On the other hand, recent trends of petroleum industry are directed toward unconventional resources such as heavy oil and methane hydrate in weakly-consolidated to unconsolidated sands. However, the hydraulic fracturing behavior in unconsolidated formation has not been fully understood. To achieve this goal, we are conducting a study to establish the theory of hydraulic fracturing in unconsolidated formation with both experimental and numerical approaches.<\/div>\r\n<div class=\"photo\">\r\n<div class=\"clearfix\">\r\n<ul class=\"songle\">\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/division\/21_img\/21_001.jpg\" \/>(a) Originally designed apparatus for unconsolidated rock hydraulic fracturing experiment.
