  • Rotating casing assembly and method
    Patent number: 6446725
    Abstract: The rotating casing assembly and method, as described herein, allows for rotation of the casing at any depth to decrease the chance of microchannelling along the annulus. The assembly includes a casing section mounted through a bearing device to a casing string. The casing section is driven to rotate as permitted by the bearing by the energy of the fluid being pumped through the casing and across vanes in the casing section.
