Abstract

An activation device (10) for use in a downhole well for activation of a downhole tool in the well. The downhole tool has a seat (103) adapted to engage the activation device. The activation device can travel through a borehole of the downhole well to reach the seat. The activation device has an outer layer (22) and a core (24). The material of the outer layer resists erosion by drilling fluid when the activation device is in the borehole. The material of the core is eroded by drilling fluid when the activation device is engaged in the seat. The activation device (10) is then able to pass through the seat (103) There is also described a method of operating a downhole tool having a seat (103) for engaging an activation device. The method includes the step of eroding at least a portion of the activation device with drilling fluid until it can pass through the seat.
