Abstract
A method for releasably, acoustically-coupling an acoustical-energy sensor in a wellbore wherein the sensor is lowered in the wellbore and a soluble cement is flowed into the wellbore to completely encompass the sensor. The soluble cement is allowed to harden to physically bond and thereby acoustically couple the sensor to said wellbore. When it is desired to remove the sensors, a solvent is flowed down the wellbore and into contact with the hardened soluble cement to dissolve the soluble cement. The dissolved cement is then circulated out of the well and the sensors removed so that the well is again available for other operations.
