Abstract
A well packer can include a seal element adapted to extend continuously about a tubular, the seal element including a swellable material, and multiple longitudinally extending cement flow channels formed on an exterior of the seal element. A method of constructing a well packer for use in cementing a tubular in a wellbore can include forming a seal element having multiple longitudinally extending cement flow channels on an exterior thereof, the seal element including a swellable material, and positioning the seal element on the tubular, the seal element extending continuously about the tubular. A method of cementing a tubular in a wellbore can include flowing cement through an annulus between the tubular string and the wellbore, the flowing including flowing the cement through multiple longitudinally extending cement flow channels on a seal element which continuously encircles the tubular, and swelling a swellable material of the seal element.
