Abstract
As unconventional reservoirs seize a more and more pronounced market share today, to understand the mechanical behavior of such systems throughout the production lifetime is becoming increasingly intriguing. The current acoustic logging tools emit energy to the full azimuth without control, thus limited spatial resolution and depth of investigation can be achieved due to the lack of penetration power. A next generation transduction technology that is able to steer the sound beam azimuthally, axially and radially are therefore in urgent need. In this talk, we present an acoustic beam steering and focusing method in casedwellbore geometry. The method is valuable for cement evaluation in multi-string cased-wells and a high resolution scanning of mechanical properties in surrounding rock formations.
