Abstract:
A method of placing at least one acoustic device in a wellbore, comprising:(a) providing a tubing string for production or injection of fluid in said wellbore with at least one anchoring device, said tubing having a fluid flowing therein, said at lease one anchoring device attached to an external section of said tubing through an acoustic isolator, said anchoring device having a plurality of slips extendable to a casing disposed in the wellbore to exert a force on the casing, each of said slips having at least one set of teeth mounted to firmly set into the casing when said plurality of slips exerts force on said casing; (b) attaching the at least one acoustic device to the at least one anchoring device so that the acoustic device is located in an annulus between the tubing and the casing when the tubing string is placed in the wellbore; (c) placing said tubing string with the at least one acoustic device attached to said at least one anchoring device in the wellbore; and (d) extending the anchoring device to the casing to exert force on the casing, thereby firmly setting said teeth into the casing and coupling the acoustic device to the casing.
