Abstract
A ported collar has a tubular body that forms part of or is installed in a tubular that is run into a wellbore, and defines a port for permitting radial fluid communication into or out of the ported collar. A sleeve is movable relative to the port to vary an open area of the port. The activation device includes a fixed key and a traveling key movable relative to the fixed key. The activation device is inserted into the tubular body of the ported collar. A fixed key profile is releasably mated with a tubular body key profile to fix the position of the activation device in the ported collar. A traveling key profile is releasably mated with a sliding sleeve key profile, and the traveling key is moved relative to the fixed key to move the sliding sleeve, and thereby vary the open area of the port.
