Abstract

A centraliser has a body with a bore to receive a tubular and has blades 75 with at least one groove 81 in the outer face of the blades 75, which channels fluids through the groove 81 axially along the blade 75. The groove 81 can have a different depth, width, volume or radius of curvature at one end as compared with the other, and can have a ramp at one end of the blade 81. Optionally, only one end of the groove 81 is open and the other (e.g. the upper) end is closed. The groove 81 can be parallel to an axis of the blade 75. More than one groove can be provided on the blade, including lateral grooves 82.
