Abstract
A method and apparatus is disclosed for monitoring microseismic activity in a formation. The method and apparatus include placing a tool string having a shuttle including a sensor thereon in a stimulation well, and activating the shuttle to acoustically couple the sensor to an inner surface of a casing. The sensor is acoustically decoupled from the tool string. Fluid is then injected into the formation via the tool string. The sensor is reengaged with the tool string. The tool string may then be removed from the stimulation well or moved to another position along the wellbore.
