Estimating the term…
A wellbore can be cemented by injecting into the wellbore a cement slurry comprising an accelerator composite having a shell encapsulating a core comprising an accelerator; a cementitious material; and an aqueous carrier; passing the cement slurry through a tool that includes an ultrasonic emitter, emitting ultrasonic waves from the ultrasonic emitter as the cement slurry passes the ultrasonic emitter to break the shell releasing the accelerator from the accelerator composite and activating the cement slurry. This process can be implemented using a tool with includes a tube through which cement slurry can be injected into the wellbore and an ultrasonic emitter positioned to direct ultrasonic waves onto the cement slurry as is moves through the tube.
A tool for use in wellbore formation comprising a tube through which a cement slurry can be injected into a wellbore, one or more ultrasonic emitters which can be positioned to direct ultrasonic waves onto the cement slurry as the cement slurry moves through the tube and can be positioned to emit and sense ultrasonic waves in an outward direction for inspection of the wellbore, wherein the inspection comprises locating a casing collar.
A method of cementing a wellbore, the method comprising:
