Abstract

<p>Enhanced oil recovery（EOR）and improved oil recovery（IOR）technologies have been applied to various oil and gas fields for many years. However, the environment for EOR/IOR has been severe in low oil price and increase of development cost and more effective and economical EOR technology is expected. We focused the application of micro bubble as cutting-edge EOR technology.</p><p>Micro bubble technology has been applied to various industries as medical, agriculture and environment fields. And micro bubble has some characteristics in relative to the effect of EOR such as improvement of sweep efficiency and oil density and viscosity.</p><p>We have studied about the efficiency of micro bubble technology and its mechanism from laboratory test and flow simulation. We evaluated the improvement of the sweep efficiency, solubility to oil and oil recovery by micro bubble injection from core flooding test which was one of the laboratory tests and it was indicated that the capillary pressure affected the injection area from flow simulation.</p><p>We expect micro bubble technology will become useful as new EOR technology from our study.</p>
